--- _id: '18192' abstract: - lang: eng text: Current quantum simulation experiments are starting to explore nonequilibrium many-body dynamics in previously inaccessible regimes in terms of system sizes and timescales. Therefore, the question emerges as to which observables are best suited to study the dynamics in such quantum many-body systems. Using machine learning techniques, we investigate the dynamics and, in particular, the thermalization behavior of an interacting quantum system that undergoes a nonequilibrium phase transition from an ergodic to a many-body localized phase. We employ supervised and unsupervised training methods to distinguish nonequilibrium from equilibrium data, using the network performance as a probe for the thermalization behavior of the system. We test our methods with experimental snapshots of ultracold atoms taken with a quantum gas microscope. Our results provide a path to analyze highly entangled large-scale quantum states for system sizes where numerical calculations of conventional observables become challenging. article_number: '150504' article_processing_charge: No article_type: original arxiv: 1 author: - first_name: A. full_name: Bohrdt, A. last_name: Bohrdt - first_name: S. full_name: Kim, S. last_name: Kim - first_name: A. full_name: Lukin, A. last_name: Lukin - first_name: M. full_name: Rispoli, M. last_name: Rispoli - first_name: R. full_name: Schittko, R. last_name: Schittko - first_name: M. full_name: Knap, M. last_name: Knap - first_name: M. full_name: Greiner, M. last_name: Greiner - first_name: Julian full_name: Leonard, Julian id: b75b3f45-7995-11ef-9bfd-9a9cd02c3577 last_name: Leonard citation: ama: Bohrdt A, Kim S, Lukin A, et al.

We show that entanglement between the two degrees of freedom weakens localization due to the upper bound imposed on the inverse participation ratio by purity of a quantum state. We perform numerical calculations for a two-particle system bound by a harmonic force in a 1D disordered lattice and a rigid rotor in a 2D disordered lattice. We illustrate that the coupling has a dramatic effect on localization properties, even with a small number of internal states participating in quantum dynamics. acknowledgement: "We acknowledge helpful discussions with W.

To accomplish this, we combine an evolutionary algorithm with coarse-grained molecular dynamics simulations and explore the solution space of ligand patterns on a nanoparticle that promote efficient and reliable cell uptake. Surprisingly, we find that in the regime of low ligand number the best-performing structures are characterized by ligands arranged into long one-dimensional chains that pattern the surface of the particle. We show that these chains of ligands provide particles with high rotational freedom and they lower the free energy barrier for membrane crossing. Our approach reveals a set of nonintuitive design rules that can be used to inform artificial nanoparticle construction and the search for inhibitors of viral entry. acknowledgement: We acknowledge support from EPSRC (J.

By developing a coarse-grained computer model we find that clustering promotes the channel closure, which is highly dependent on the channel concentration and membrane stress. This behaviour yields a tightly regulated gating system, whereby at high tensions channels gate individually, and at lower tensions the channels spontaneously aggregate and inactivate. We implement this positive feedback into the model for cell volume regulation, and find that the channel clustering protects the cell against excessive loss of cytoplasmic content. acknowledgement: We thank Samantha Miller, Bert Poolman, and the members of Šarić and Pilizota laboratories for useful discussion.

We validate the dynamical relevance of such solutions by demonstrating that turbulent flows in both experiment and numerics transiently display time-periodic dynamics when they shadow unstable periodic orbits (UPOs). We show that UPOs we computed are also statistically significant, with turbulent flows spending a sizable fraction of the total time near these solutions. As a result, the average rates of energy input and dissipation for the turbulent flow and frequently visited UPOs differ only by a few percent. acknowledgement: M. F. S. and R. O.

However, the GK method relies on an ambiguous definition of the microscopic heat flux, which depends on how one chooses to distribute energies over atoms. This ambiguity makes it problematic to employ the GK method for systems with nonpairwise interactions. In this work, we show that the hydrodynamic description of thermally driven density fluctuations can be used to obtain the thermal conductivity of a bulk fluid unambiguously, thereby bypassing the need to define the heat flux. We verify that, for a model fluid with only pairwise interactions, our method yields estimates of thermal conductivity consistent with the GK approach. We apply our approach to compute the thermal conductivity of a nonpairwise additive water model at supercritical conditions, and of a liquid hydrogen system described by a machine-learning interatomic potential, at 33 GPa and 2000 K. article_number: '130602' article_processing_charge: No article_type: original arxiv: 1 author: - first_name: Bingqing full_name: Cheng, Bingqing id: cbe3cda4-d82c-11eb-8dc7-8ff94289fcc9 last_name: Cheng orcid: 0000-0002-3584-9632 - first_name: Daan full_name: Frenkel, Daan last_name: Frenkel citation: ama: Cheng B, Frenkel D.

Using a symmetry decomposition of the conductance, we find that antisymmetric components of pairs of local and nonlocal conductances qualitatively match at energies below the superconducting gap, and we compare this finding with symmetry relations based on a noninteracting scattering matrix approach. Further, the local charge character of Andreev bound states is extracted from the symmetry-decomposed conductance data and is found to be similar at both ends of the device and tunable with gate voltage. Finally, we measure the conductance matrix as a function of magnetic field and identify correlated splittings in low-energy features, demonstrating how conductance-matrix measurements can complement traditional single-probe measurements in the search for Majorana zero modes. article_number: '036802' article_processing_charge: No article_type: original arxiv: 1 author: - first_name: G. C. full_name: Ménard, G. C. last_name: Ménard - first_name: G. L. R. full_name: Anselmetti, G. L. R. last_name: Anselmetti - first_name: E. A. full_name: Martinez, E. A. last_name: Martinez - first_name: D. full_name: Puglia, D. last_name: Puglia - first_name: F. K. full_name: Malinowski, F. K. last_name: Malinowski - first_name: J. S. full_name: Lee, J. S. last_name: Lee - first_name: S. full_name: Choi, S. last_name: Choi - first_name: M. full_name: Pendharkar, M. last_name: Pendharkar - first_name: C. J. full_name: Palmstrøm, C. J. last_name: Palmstrøm - first_name: K. full_name: Flensberg, K. last_name: Flensberg - first_name: C. M. full_name: Marcus, C. M. last_name: Marcus - first_name: L. full_name: Casparis, L. last_name: Casparis - first_name: Andrew P full_name: Higginbotham, Andrew P id: 4AD6785A-F248-11E8-B48F-1D18A9856A87 last_name: Higginbotham orcid: 0000-0003-2607-2363 citation: ama: Ménard GC, Anselmetti GLR, Martinez EA, et al.

Here, we study theoretically a three-terminal setup, with two normal leads coupled to a grounded superconducting terminal. Using a single-electron scattering matrix, we derive the subgap conductance matrix for the normal leads and discuss its symmetries. In particular, we show that the local and the nonlocal elements of the conductance matrix have pairwise identical antisymmetric components. Moreover, we find that the nonlocal elements are directly related to the local BCS charges of the bound states close to the normal probes and we show how the BCS charge of overlapping Majorana bound states can be extracted from experiments. article_number: '036801' article_processing_charge: No article_type: original arxiv: 1 author: - first_name: Jeroen full_name: Danon, Jeroen last_name: Danon - first_name: Anna Birk full_name: Hellenes, Anna Birk last_name: Hellenes - first_name: Esben Bork full_name: Hansen, Esben Bork last_name: Hansen - first_name: Lucas full_name: Casparis, Lucas last_name: Casparis - first_name: Andrew P full_name: Higginbotham, Andrew P id: 4AD6785A-F248-11E8-B48F-1D18A9856A87 last_name: Higginbotham orcid: 0000-0003-2607-2363 - first_name: Karsten full_name: Flensberg, Karsten last_name: Flensberg citation: ama: 'Danon J, Hellenes AB, Hansen EB, Casparis L, Higginbotham AP, Flensberg K.

Our analysis suggests the existence of an underlying nonintegrableHamiltonian which supports an emergent SU(2)-spin dynamics within a small subspace of the many-bodyHilbert space. We show that such perfect dynamics necessitates the existence of atypical, nonergodicenergy eigenstates—quantum many-body scars. Furthermore, using these insights, we construct a toymodel that hosts exact quantum many-body scars, providing an intuitive explanation of their origin. Ourresults offer specific routes to enhancing coherent many-body revivals and provide a step towardestablishing the stability of quantum many-body scars in the thermodynamic limit. article_number: '220603' article_processing_charge: No article_type: original arxiv: 1 author: - first_name: Soonwon full_name: Choi, Soonwon last_name: Choi - first_name: Christopher J. full_name: Turner, Christopher J. last_name: Turner - first_name: Hannes full_name: Pichler, Hannes last_name: Pichler - first_name: Wen Wei full_name: Ho, Wen Wei last_name: Ho - first_name: Alexios full_name: Michailidis, Alexios id: 36EBAD38-F248-11E8-B48F-1D18A9856A87 last_name: Michailidis orcid: 0000-0002-8443-1064 - first_name: Zlatko full_name: Papić, Zlatko last_name: Papić - first_name: Maksym full_name: Serbyn, Maksym id: 47809E7E-F248-11E8-B48F-1D18A9856A87 last_name: Serbyn orcid: 0000-0002-2399-5827 - first_name: Mikhail D. full_name: Lukin, Mikhail D. last_name: Lukin - first_name: Dmitry A. full_name: Abanin, Dmitry A. last_name: Abanin citation: ama: Choi S, Turner CJ, Pichler H, et al.

Here we show that if migration traps develop in the accretion disks of active galactic nuclei (AGNs) and promote the mergers of their captive black holes, the majority of black holes within disks will undergo hierarchical mergers—with one of the black holes being the remnant of a previous merger. 40% of AGN-assisted mergers detected by LIGO/Virgo will include a black hole with mass ≳50⁢\U0001D440⊙, the mass limit from stellar core collapse. Hierarchical mergers at traps in AGNs will exhibit black hole spins (anti)aligned with the binary’s orbital axis, a distinct property from other hierarchical channels. Our results suggest, although not definitively (with odds ratio of ∼1), that LIGO’s heaviest merger so far, GW170729, could have originated from this channel." article_number: '181101' article_processing_charge: No article_type: original arxiv: 1 author: - first_name: Y. full_name: Yang, Y. last_name: Yang - first_name: I. full_name: Bartos, I. last_name: Bartos - first_name: V. full_name: Gayathri, V. last_name: Gayathri - first_name: K. E. S. full_name: Ford, K. E. S. last_name: Ford - first_name: Zoltán full_name: Haiman, Zoltán id: 7c006e8c-cc0d-11ee-8322-cb904ef76f36 last_name: Haiman - first_name: S. full_name: Klimenko, S. last_name: Klimenko - first_name: B. full_name: Kocsis, B. last_name: Kocsis - first_name: S. full_name: Márka, S. last_name: Márka - first_name: Z. full_name: Márka, Z. last_name: Márka - first_name: B. full_name: McKernan, B. last_name: McKernan - first_name: R. full_name: O’Shaughnessy, R. last_name: O’Shaughnessy citation: ama: Yang Y, Bartos I, Gayathri V, et al.

Our approach relies on a family of RG flows parametrized by the asymmetry between thermal and localized phases. We identify the physical MBL transition in the limit of maximal asymmetry, reflecting the instability of MBL against rare thermal inclusions. We find a critical point that is localized with power-law distributed thermal inclusions. The typical size of critical inclusions remains finite at the transition, while the average size is logarithmically diverging. We propose a two-parameter scaling theory for the many-body localization transition that falls into the Kosterlitz-Thouless universality class, with the MBL phase corresponding to a stable line of fixed points with multifractal behavior. article_number: '040601' article_processing_charge: No article_type: original arxiv: 1 author: - first_name: Anya full_name: Goremykina, Anya last_name: Goremykina - first_name: Romain full_name: Vasseur, Romain last_name: Vasseur - first_name: Maksym full_name: Serbyn, Maksym id: 47809E7E-F248-11E8-B48F-1D18A9856A87 last_name: Serbyn orcid: 0000-0002-2399-5827 citation: ama: Goremykina A, Vasseur R, Serbyn M.

Comparing PdTe2 with its sister compound PtSe2, we demonstrate how enhanced interlayer hopping in the Te-based material drives a band inversion within the antibonding \U0001D45D-orbital manifold well above the Fermi level. We show how this mediates spin-polarized topological surface states which form rich multivalley Fermi surfaces with complex spin textures. Scanning tunneling spectroscopy reveals type-II superconductivity at the surface, and moreover shows no evidence for an unconventional component of its superconducting order parameter, despite the presence of topological surface states." article_number: '156401' article_processing_charge: No article_type: original arxiv: 1 author: - first_name: O. J. full_name: Clark, O. J. last_name: Clark - first_name: M. J. full_name: Neat, M. J. last_name: Neat - first_name: K. full_name: Okawa, K. last_name: Okawa - first_name: L. full_name: Bawden, L. last_name: Bawden - first_name: I. full_name: Marković, I. last_name: Marković - first_name: F. full_name: Mazzola, F. last_name: Mazzola - first_name: J. full_name: Feng, J. last_name: Feng - first_name: Veronika full_name: Sunko, Veronika id: 23cb1cf6-2c7a-11ef-91a4-f72fc19f20b3 last_name: Sunko orcid: 0000-0003-2724-3523 - first_name: J. M. full_name: Riley, J. M. last_name: Riley - first_name: W. full_name: Meevasana, W. last_name: Meevasana - first_name: J. full_name: Fujii, J. last_name: Fujii - first_name: I. full_name: Vobornik, I. last_name: Vobornik - first_name: T. K. full_name: Kim, T. K. last_name: Kim - first_name: M. full_name: Hoesch, M. last_name: Hoesch - first_name: T. full_name: Sasagawa, T. last_name: Sasagawa - first_name: P. full_name: Wahl, P. last_name: Wahl - first_name: M. S. full_name: Bahramy, M. S. last_name: Bahramy - first_name: P. D. C. full_name: King, P. D. C. last_name: King citation: ama: Clark OJ, Neat MJ, Okawa K, et al.

Here, we report FQH thermal activation gap measurements in dual graphite-gated monolayer graphene devices fabricated in an edgeless Corbino geometry. In devices with substrate-induced sublattice splitting, we find a tunable crossover between single- and multicomponent FQH states in the zero energy Landau level. Activation gaps in the single-component regime show excellent agreement with numerical calculations using a single broadening parameter \r\nΓ≈7.2K. In the first excited Landau level, in contrast, FQH gaps are strongly influenced by Landau level mixing, and we observe an unexpected valley-ordered state at integer filling ν=−4." acknowledgement: We thank Cory Dean, S.

We show that the diffusivity of hydrogen in the lattice of bcc iron deviates strongly from an Arrhenius behavior at and below room temperature. We compare a quantum transition state theory to explicit ring polymer molecular dynamics in the calculation of diffusivity. We then address the trapping of hydrogen by a vacancy as a prototype lattice defect. By a sequence of steps in a thought experiment, each involving a thermodynamic integration, we are able to separate out the binding free energy of a proton to a defect into harmonic and anharmonic, and classical and quantum contributions. We find that about 30% of a typical binding free energy of hydrogen to a lattice defect in iron is accounted for by finite temperature effects, and about half of these arise from quantum proton fluctuations. This has huge implications for the comparison between thermal desorption and permeation experiments and standard electronic structure theory. The implications are even greater for the interpretation of muon spin resonance experiments. article_number: '225901' article_processing_charge: No article_type: review arxiv: 1 author: - first_name: Bingqing full_name: Cheng, Bingqing id: cbe3cda4-d82c-11eb-8dc7-8ff94289fcc9 last_name: Cheng orcid: 0000-0002-3584-9632 - first_name: Anthony T. full_name: Paxton, Anthony T. last_name: Paxton - first_name: Michele full_name: Ceriotti, Michele last_name: Ceriotti citation: ama: 'Cheng B, Paxton AT, Ceriotti M.

Here we demonstrate that experimental data collected over the last 20 years provide evidence that molecules immersed in superfluid helium form recently-predicted angulon quasiparticles [Phys. Rev. Lett. 114, 203001 (2015)]. Most importantly, casting the many-body problem in terms of angulons amounts to a drastic simplification and yields effective molecular moments of inertia as straightforward analytic solutions of a simple microscopic Hamiltonian. The outcome of the angulon theory is in good agreement with experiment for a broad range of molecular impurities, from heavy to medium-mass to light species. These results pave the way to understanding molecular rotation in liquid and crystalline phases in terms of the angulon quasiparticle. article_number: '095301' article_processing_charge: No arxiv: 1 author: - first_name: Mikhail full_name: Lemeshko, Mikhail id: 37CB05FA-F248-11E8-B48F-1D18A9856A87 last_name: Lemeshko orcid: 0000-0002-6990-7802 citation: ama: Lemeshko M.
