The time-dependent degree of alignment is recorded using femtosecond-probe-pulse-induced Coulomb explosion into a pair of Ak+ fragment ions. The results, obtained for Na2, K2, and Rb2 in both the ground state 11Σ+g and the lowest-lying triplet state 13Σ+u, exhibit distinct, periodic revivals with a gradually decreasing amplitude. The dynamics differ from that expected for dimers had they behaved as free rotors. Numerically, we solve the time-dependent rotational Schrödinger equation, including an effective mean-field potential to describe the interaction between the dimer and the droplet. The experimental and simulated alignment dynamics agree well and their comparison enables us to determine the effective rotational constants of the alkali dimers with the exception of Rb2(13Σ+u) that only exhibits a prompt alignment peak but no subsequent revivals. For Na2(13Σ+u), K2(11Σ+g), K2(13Σ+u) and Rb2(11Σ+g), the alignment dynamics are well-described by a 2D rotor model. We ascribe this to a significant confinement of the internuclear axis of these dimers, induced by the orientation-dependent droplet-dimer interaction, to the tangential plane of their residence point on the droplet."}],"article_number":"033114","volume":111,"quality_controlled":"1","author":[{"first_name":"Henrik H.","full_name":"Kristensen, Henrik H.","last_name":"Kristensen"},{"last_name":"Kranabetter","full_name":"Kranabetter, Lorenz","first_name":"Lorenz"},{"first_name":"Areg","id":"4AF46FD6-F248-11E8-B48F-1D18A9856A87","last_name":"Ghazaryan","full_name":"Ghazaryan, Areg","orcid":"0000-0001-9666-3543"},{"full_name":"Schouder, Constant A.","last_name":"Schouder","first_name":"Constant A."},{"last_name":"Hansen","full_name":"Hansen, Emil","first_name":"Emil"},{"last_name":"Jensen","full_name":"Jensen, Frank","first_name":"Frank"},{"last_name":"Zillich","full_name":"Zillich, Robert E.","first_name":"Robert E."},{"orcid":"0000-0002-6990-7802","id":"37CB05FA-F248-11E8-B48F-1D18A9856A87","first_name":"Mikhail","full_name":"Lemeshko, Mikhail","last_name":"Lemeshko"},{"last_name":"Stapelfeldt","full_name":"Stapelfeldt, Henrik","first_name":"Henrik"}],"publication":"Physical Review A","scopus_import":"1","intvolume":"       111","isi":1,"main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.2502.14521"}],"acknowledgement":"H.S. acknowledges support from the Villum Foundation through a Villum Investigator Grant No. 25886.

We outline measurable manifestations of the Pauli term in the phenomena pertaining to (i) relativistic corrections to bound states (ii) the Klein paradox, and (iii) spin effects in scattering. In particular, we demonstrate that (a) the binding energy of an electron in the vicinity of a positively charged defect is noticeably decreased due to the polarizability of lead ions and the appearance of a Darwin-like term, (b) strong spin-orbit coupling due to the Pauli term affects the exciton states, and (c) scattering of an electron off an energy barrier with broken mirror symmetry produces spin polarization in the outgoing current. Our study adds to the understanding of quantum phenomena in lead-halide perovskites and paves the way for tabletop simulations of analog Dirac-Pauli equations."}],"license":"https://creativecommons.org/licenses/by-nc-nd/4.0/","article_number":"37"},{"author":[{"orcid":"0000-0002-6963-0129","first_name":"Volker","id":"D7C012AE-D7ED-11E9-95E8-1EC5E5697425","last_name":"Karle","full_name":"Karle, Volker"}],"file_date_updated":"2025-03-20T08:02:35Z","file":[{"date_created":"2025-03-12T12:56:46Z","file_id":"19394","creator":"vkarle","file_name":"thesis_final.pdf","file_size":10625143,"checksum":"d3ab25782c7ea38ce9910e57d25f6733","content_type":"application/pdf","date_updated":"2025-03-12T12:56:46Z","success":1,"relation":"main_file","access_level":"open_access"},{"checksum":"3ccfb0aeba4d860d71e18347913034e4","content_type":"application/zip","date_updated":"2025-03-20T08:02:35Z","file_id":"19400","date_created":"2025-03-13T13:15:10Z","creator":"vkarle","file_name":"thesis.zip","file_size":23119202,"relation":"source_file","access_level":"closed"}],"oa":1,"publication_identifier":{"eissn":["2663-337X"]},"degree_awarded":"PhD","publication_status":"published","department":[{"_id":"GradSch"},{"_id":"MiLe"}],"date_created":"2025-03-12T13:04:59Z","corr_author":"1","language":[{"iso":"eng"}],"abstract":[{"lang":"eng","text":"Rotations constitute one of the fundamental symmetries in physics, characterized by their intricate group structure and infinite dimensional representations. In contrast to classical rotations, quantum mechanics unveils the SO(3) symmetry group structure, manifesting in phenomena without classical counterparts, from angular momentum quantization to non-trivial addition of angular momenta.\r\nWhile most studies of topological physics have focused on two-band systems, the SO(3) symmetry group of quantum rotors offers an inherently more complex platform with unprecedented possibilities for exploring topological phenomena. Despite their ubiquity in nature– from molecules to nanorotors– their potential for hosting topological phases has remained largely unexamined.\r\nIn this thesis, we mainly focus on periodically driven linear molecules as a prototype for studying topological phenomena in quantum rotors. Recent technological advances in coherent control of molecules, particularly through precisely shaped laser pulses, have made it possible to investigate linear rotors in the context of topology. While planar rotors have received some attention in recent years, threedimensional rotors–particularly linear molecules–harbor substantially richer topological phenomena due to their non-abelian nature and their additional angular degrees of freedom. We demonstrate that these systems can host novel edge states and topological features fundamentally impossible in planar systems.\r\nWe begin by establishing a theoretical bridge between periodically kicked rotors and \"crystalline\" lattices in angular momentum space. Using non-interacting linear molecules as our primary example, we show how quantum interference and revival patterns lead to the possibility to simulate band models with arbitrary number of bands N. While our framework applies to various quantum rotors, including nanorotors and kicked Bose-Einstein condensates, linear\r\nmolecules provide an ideal experimental platform due to their abovementioned precise controllability.\r\nThe core of this work examines adiabatic dynamics of 3D quantum rotors, establishing a geometric framework based on the Euler class to characterize its non-abelian topology. The non-Hermitian nature of the system enables novel braiding behaviors and topological transitions impossible in static systems, leading to an anomalous Dirac string phase with edge states in each gap, even though the Berry phases are all zero. These features can be directly observed through\r\nmolecular alignment and rotational level populations.\r\nThese findings establish quantum rotors as an alternative platform for studying multi-band topological physics, while suggesting practical implementations for quantum computation where topological protection could offer natural resilience against decoherence. The rich structure of three-dimensional rotation groups, combined with the tunability of topological features through driving parameters, makes this platform particularly valuable for exploring fundamental\r\nphysics and developing quantum technologies."}],"supervisor":[{"orcid":"0000-0002-6990-7802","id":"37CB05FA-F248-11E8-B48F-1D18A9856A87","first_name":"Mikhail","last_name":"Lemeshko","full_name":"Lemeshko, Mikhail"}],"has_accepted_license":"1","date_published":"2025-03-13T00:00:00Z","oa_version":"Published Version","year":"2025","date_updated":"2026-04-07T11:48:53Z","user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","page":"192","status":"public","tmp":{"name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)","image":"/images/cc_by_nc_nd.png","short":"CC BY-NC-ND (4.0)","legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode"},"publisher":"Institute of Science and Technology Austria","day":"13","type":"dissertation","ddc":["530"],"OA_place":"publisher","doi":"10.15479/AT-ISTA-19393","alternative_title":["ISTA Thesis"],"OA_type":"gold","_id":"19393","title":"Non-equilibrium topological phases with periodically driven molecules and quantum rotors","month":"03","article_processing_charge":"No","citation":{"apa":"Karle, V.

Unlike spatial displacements, rotational transformations in three-dimensional space  are non-commutative: the result of applying a sequence of rotations depends on the order of these operations. This feature makes the emergent physics that involves rotations rather intricate, but instrumental for studies of highly-interconnected many-body systems. In the presence of an environment, rotational properties of an object change, due to the interaction with particles of the environment. Owing to the complexity of this interaction, it can be engineered to exhibit certain properties of interest.

Our focus is on systems where isotropic or anisotropic impurity-boson interactions support a shallow bound state. To study the fate of the angulon in the vicinity of bound-state formation, we formulate a beyond-linear-coupling angulon Hamiltonian. First, we use it to study attractive, spherically symmetric impurity-boson interactions for which the linear rotor can be mapped onto a static impurity. The well-known polaron formalism provides an adequate description in this limit. Second, we consider anisotropic potentials, and show that the presence of a shallow bound state with pronounced anisotropic character leads to a many-body instability that washes out the angulon dynamics.","lang":"eng"}],"publication_status":"published","language":[{"iso":"eng"}],"corr_author":"1","date_created":"2024-01-21T23:00:57Z","external_id":{"isi":["001172754500002"],"arxiv":["2308.03852"]},"department":[{"_id":"MiLe"}],"status":"public","issue":"1","day":"01","type":"journal_article","publisher":"American Physical Society","date_updated":"2025-09-04T11:49:14Z","year":"2024","oa_version":"Preprint","project":[{"name":"Angulon: physics and applications of a new quasiparticle","call_identifier":"H2020","grant_number":"801770","_id":"2688CF98-B435-11E9-9278-68D0E5697425"},{"grant_number":"754411","_id":"260C2330-B435-11E9-9278-68D0E5697425","call_identifier":"H2020","name":"ISTplus - Postdoctoral Fellowships"}],"date_published":"2024-01-01T00:00:00Z","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","month":"01","title":"Linear rotor in an ideal Bose gas near the threshold for binding","_id":"14845","citation":{"ieee":"T.

They are, however, often optimized to address a specific type of problem. Here, we present the design and implementation of a 6Li-based quantum gas platform that provides wide-ranging capabilities and is able to address a variety of quantum many-body problems. Our two-chamber architecture relies on a robust combination of gray molasses and optical transport from a laser-cooling chamber to a glass cell with excellent optical access. There, we first create unitary Fermi superfluids in a three-dimensional axially symmetric harmonic trap and characterize them using in situ thermometry, reaching temperatures below 20 nK. This allows us to enter the deep superfluid regime with samples of extreme diluteness, where the interparticle spacing is sufficiently large for direct single-atom imaging. Second, we generate optical lattice potentials with triangular and honeycomb geometry in which we study diffraction of molecular Bose-Einstein condensates, and show how going beyond the Kapitza-Dirac regime allows us to unambiguously distinguish between the two geometries. With the ability to probe quantum many-body physics in both discrete and continuous space, and its suitability for bulk and single-atom imaging, our setup represents an important step towards achieving a wide-scope quantum simulator."}],"article_number":"013158","publication_status":"published","external_id":{"arxiv":["2304.08433"]},"department":[{"_id":"MiLe"}],"date_created":"2024-03-04T07:42:52Z","language":[{"iso":"eng"}],"DOAJ_listed":"1","file":[{"checksum":"ba2ae3e3a011f8897d3803c9366a67e2","content_type":"application/pdf","date_updated":"2024-03-04T07:53:08Z","creator":"dernst","file_name":"2024_PhysicalReviewResearch_Jin.pdf","file_id":"15054","date_created":"2024-03-04T07:53:08Z","file_size":4025988,"access_level":"open_access","relation":"main_file","success":1}],"acknowledgement":"We thank Clara Bachorz, Darby Bates, Markus Bohlen, Valentin Crépel, Yann Kiefer, Joanna Lis, Mihail Rabinovic, and Julian Struck for experimental assistance in the early stages of this project, and Sebastian Will for a critical reading of the manuscript.

Increasing repulsion leads to the appearance of nonadiabatic couplings between the fast bath and slow impurity degrees of freedom, which reduce the parity symmetry of the latter according to the pseudo Jahn-Teller effect. The presence of this mechanism is associated to a conical intersection involving the impurity position and the inverse of the interaction strength, which acts as a synthetic dimension. We elucidate the presence of these effects via a detailed ground-state analysis involving the comparison of ab initio fully correlated simulations with effective models.

This approximation assumes that the timescale of the laser-molecule interaction is significantly shorter than the internal rotational period of the molecule, resulting in the rotational motion being instantaneously “frozen” during the interaction. This simplified description of the laser-molecule interaction is incorporated in various theoretical models predicting rotational dynamics of molecules driven by short laser pulses. In this theoretical work, we develop an effective theory for ultrashort laser pulses by examining the full time-evolution operator and solving the time-dependent Schrödinger equation at the operator level. Our findings reveal a critical angular momentum, lcrit, at which the impulsive limit breaks down. In other words, the validity of the sudden approximation depends not only on the pulse duration but also on its intensity, since the latter determines how many angular momentum states are populated. We explore both ultrashort multicycle (Gaussian) pulses and the somewhat less studied half-cycle pulses, which produce distinct effective potentials. We discuss the limitations of the impulsive limit and propose a method that rescales the effective matrix elements, enabling an improved and more accurate description of laser-molecule interactions.","lang":"eng"}],"article_number":"023101","quality_controlled":"1","volume":109,"language":[{"iso":"eng"}],"corr_author":"1","external_id":{"arxiv":["2307.07256"],"isi":["001158043800006"]},"department":[{"_id":"MiLe"}],"date_created":"2024-02-18T23:01:01Z","publication_status":"published"},{"file":[{"success":1,"relation":"main_file","access_level":"open_access","file_id":"14878","date_created":"2024-01-23T12:18:07Z","creator":"dernst","file_name":"2024_PhysikZeit_Karle.pdf","file_size":1155244,"content_type":"application/pdf","checksum":"3051dadcf9bc57da97e36b647c596ab1","date_updated":"2024-01-23T12:18:07Z"}],"publication_identifier":{"issn":["0031-9252"],"eissn":["1521-3943"]},"oa":1,"publication":"Physik in unserer Zeit","author":[{"last_name":"Karle","full_name":"Karle, Volker","id":"D7C012AE-D7ED-11E9-95E8-1EC5E5697425","first_name":"Volker","orcid":"0000-0002-6963-0129"},{"last_name":"Lemeshko","full_name":"Lemeshko, Mikhail","id":"37CB05FA-F248-11E8-B48F-1D18A9856A87","first_name":"Mikhail","orcid":"0000-0002-6990-7802"}],"file_date_updated":"2024-01-23T12:18:07Z","keyword":["General Earth and Planetary Sciences","General Environmental Science"],"intvolume":"        55","volume":55,"quality_controlled":"1","abstract":[{"text":"Die Quantenrotation ist ein spannendes Phänomen, das in vielen verschiedenen Systemen auftritt, von Molekülen und Atomen bis hin zu subatomaren Teilchen wie Neutronen und Protonen.

By adiabatically varying the periodic kicks to the rotor we find nodal-line braiding, which causes sign flips of topological charges of band nodes and can prevent them from annihilating, indicated by non-zero values of the %non-Abelian patch Euler class. In particular, we report\r\non the emergence of an anomalous Dirac string phase arising in the strongly driven regime, a truly out-of-equilibrium phase of the quantum rotor. This phase emanates from braiding processes involving all (quasienergy) gaps and manifests itself with edge states at zero angular momentum. Our results reveal direct applications in state-of-the-art experiments of quantum rotors, such as linear molecules driven by periodic far-off-resonant laser pulses or artificial\r\nquantum rotors in optical lattices, whose extensive versatility offers precise modification and observation of novel non-Abelian topological properties.

The light-matter interaction Hamiltonian we derive is expressed through couplings between spherical gradients of the electric field and the (transition) electric multipole moments of a particle of any nontrivial rotation point group. Our model can therefore accommodate an arbitrary complexity of the molecular and electric field structure, and it can be straightforwardly extended to atoms or nanostructures. Applying this framework to rovibrational spectroscopy of molecules, we uncover the general mechanism of angular momentum exchange between the spin and orbital angular momenta of light, molecular rotation, and its center-of-mass motion. We show that the nonzero vorticity of Laguerre-Gaussian beams can strongly enhance certain rovibrational transitions that are considered forbidden in the case of nonhelical light. We discuss the experimental requirements for the observation of these forbidden transitions in state-of-the-art spatially resolved spectroscopy measurements."}],"article_number":"033277"},{"article_number":"045115","abstract":[{"lang":"eng","text":"We present a low-scaling diagrammatic Monte Carlo approach to molecular correlation energies.

Recently, this has changed as isotopic fractionation that deviates from classical mass dependence was reported both in vitro and in vivo. In these cases, the isotopic effect correlates with the nuclear magnetic spin. Here, we show nuclear spin effects using stable oxygen isotopes (16O, 17O, and 18O) in two separate setups: an artificial dioxygen production system and biological aquaporin channels in cells. We observe that oxygen dynamics in chiral environments (in particular its transport) depend on nuclear spin, suggesting future applications for controlled isotope separation to be used, for instance, in NMR. To demonstrate the mechanism behind our findings, we formulate theoretical models based on a nuclear-spin-enhanced switch between electronic spin states. Accounting for the role of nuclear spin in biology can provide insights into the role of quantum effects in living systems and help inspire the development of future biotechnology solutions.","lang":"eng"}],"article_number":"e2300828120","quality_controlled":"1","volume":120},{"ec_funded":1,"isi":1,"intvolume":"       131","scopus_import":"1","publication":"Physical Review Letters","author":[{"full_name":"Kranabetter, Lorenz","last_name":"Kranabetter","first_name":"Lorenz"},{"first_name":"Henrik H.","full_name":"Kristensen, Henrik H.","last_name":"Kristensen"},{"full_name":"Ghazaryan, Areg","last_name":"Ghazaryan","id":"4AF46FD6-F248-11E8-B48F-1D18A9856A87","first_name":"Areg","orcid":"0000-0001-9666-3543"},{"last_name":"Schouder","full_name":"Schouder, Constant A.","first_name":"Constant A."},{"last_name":"Chatterley","full_name":"Chatterley, Adam S.","first_name":"Adam S."},{"full_name":"Janssen, Paul","last_name":"Janssen","first_name":"Paul"},{"first_name":"Frank","full_name":"Jensen, Frank","last_name":"Jensen"},{"last_name":"Zillich","full_name":"Zillich, Robert E.","first_name":"Robert E."},{"last_name":"Lemeshko","full_name":"Lemeshko, Mikhail","id":"37CB05FA-F248-11E8-B48F-1D18A9856A87","first_name":"Mikhail","orcid":"0000-0002-6990-7802"},{"last_name":"Stapelfeldt","full_name":"Stapelfeldt, Henrik","first_name":"Henrik"}],"oa":1,"publication_identifier":{"issn":["0031-9007"],"eissn":["1079-7114"]},"acknowledgement":"H.

The time-dependent degree of alignment measured, exhibits a periodic, gradually decreasing structure that deviates qualitatively from that expected for gas-phase dimers. Comparison to alignment dynamics calculated from the time-dependent rotational Schrödinger equation shows that the deviation is due to the alignment dependent interaction between the dimer and the droplet surface.
