Such lasers typically attain their stability through frequency locking to reference cavities. State-of-the-art locking performances to date had been achieved using frequency modulation based methods, complemented with active drift cancellation systems. We demonstrate an all passive, modulation-free laser-cavity locking technique (squash locking) that utilizes changes in spatial beam ellipticity for error signal generation, and a coherent polarization post-selection for noise resilience. By comparing two identically built proof-of-principle systems, we show a frequency locking instability of 5×10−7 relative to the cavity linewidth at 10 s averaging. The results surpass the demonstrated performances of methods engineered over the last five decades, potentially enabling an advancement in the precision control of lasers, while creating avenues for bridging the performance gaps between industrial grade lasers with scientific ones due to the afforded simplicity and scalability. acknowledgement: We thank Rishabh Sahu and Sebastian Wald for technical contributions to the experiment.

Among them an exact representation of quantum spin systems in terms of classical stochastic processes has been proposed. Here we provide first steps towards the extension of this stochastic approach to bosonic systems by considering the one-dimensional quantum quartic oscillator. We show how to exactly parameterize the time evolution of this prototypical model via the dynamics of a set of classical variables. We interpret these variables as stochastic processes, which allows us to propose a novel way to numerically simulate the time evolution of the system. We benchmark our findings by considering analytically solvable limits and providing alternative derivations of known results. acknowledgement: 'S.

The phase transition between non-trivial and trivial topological states is important, not only for basic materials science but also for next-generation technology, such as dissipation-free electronics4. It is therefore crucial to develop advanced probes that are suitable for a wide range of samples and environments. Here we demonstrate that circularly polarized laser-field-driven high-harmonic generation is distinctly sensitive to the non-trivial and trivial topological phases in the prototypical three-dimensional topological insulator bismuth selenide5. The phase transition is chemically initiated by reducing the spin–orbit interaction strength through the substitution of bismuth with indium atoms6,7. We find strikingly different high-harmonic responses of trivial and non-trivial topological surface states that manifest themselves as a conversion efficiency and elliptical dichroism that depend both on the driving laser ellipticity and the crystal orientation. The origins of the anomalous high-harmonic response are corroborated by calculations using the semiconductor optical Bloch equations with pairs of surface and bulk bands. As a purely optical approach, this method offers sensitivity to the electronic structure of the material, including its nonlinear response, and is compatible with a wide range of samples and sample environments. article_processing_charge: No article_type: original author: - first_name: Christian full_name: Heide, Christian last_name: Heide - first_name: Yuki full_name: Kobayashi, Yuki last_name: Kobayashi - first_name: Denitsa Rangelova full_name: Baykusheva, Denitsa Rangelova id: 71b4d059-2a03-11ee-914d-dfa3beed6530 last_name: Baykusheva - first_name: Deepti full_name: Jain, Deepti last_name: Jain - first_name: Jonathan A. full_name: Sobota, Jonathan A. last_name: Sobota - first_name: Makoto full_name: Hashimoto, Makoto last_name: Hashimoto - first_name: Patrick S. full_name: Kirchmann, Patrick S. last_name: Kirchmann - first_name: Seongshik full_name: Oh, Seongshik last_name: Oh - first_name: Tony F. full_name: Heinz, Tony F. last_name: Heinz - first_name: David A. full_name: Reis, David A. last_name: Reis - first_name: Shambhu full_name: Ghimire, Shambhu last_name: Ghimire citation: ama: Heide C, Kobayashi Y, Baykusheva DR, et al.

Chiral metasurfaces increase the electronic sensitivity to circular polarization, but their out-of-plane architecture entails manufacturing and performance trade-offs. Here, we show that nanoporous thin films of chiral nanoparticles enable high sensitivity to circular polarization due to light-induced polarization-dependent ion accumulation at nanoparticle interfaces. Self-assembled multilayers of gold nanoparticles modified with L-phenylalanine generate a photocurrent under right-handed circularly polarized light as high as 2.41 times higher than under left-handed circularly polarized light. The strong plasmonic coupling between the multiple nanoparticles producing planar chiroplasmonic modes facilitates the ejection of electrons, whose entrapment at the membrane–electrolyte interface is promoted by a thick layer of enantiopure phenylalanine. Demonstrated detection of light ellipticity with equal sensitivity at all incident angles mimics phenomenological aspects of polarization vision in marine animals. The simplicity of self-assembly and sensitivity of polarization detection found in optoionic membranes opens the door to a family of miniaturized fluidic devices for chiral photonics. article_processing_charge: No article_type: original author: - first_name: Jiarong full_name: Cai, Jiarong last_name: Cai - first_name: Wei full_name: Zhang, Wei last_name: Zhang - first_name: Liguang full_name: Xu, Liguang last_name: Xu - first_name: Changlong full_name: Hao, Changlong last_name: Hao - first_name: Wei full_name: Ma, Wei last_name: Ma - first_name: Maozhong full_name: Sun, Maozhong last_name: Sun - first_name: Xiaoling full_name: Wu, Xiaoling last_name: Wu - first_name: Xian full_name: Qin, Xian last_name: Qin - first_name: Felippe Mariano full_name: Colombari, Felippe Mariano last_name: Colombari - first_name: André Farias full_name: de Moura, André Farias last_name: de Moura - first_name: Jiahui full_name: Xu, Jiahui last_name: Xu - first_name: Mariana Cristina full_name: Silva, Mariana Cristina last_name: Silva - first_name: Evaldo Batista full_name: Carneiro-Neto, Evaldo Batista last_name: Carneiro-Neto - first_name: Weverson Rodrigues full_name: Gomes, Weverson Rodrigues last_name: Gomes - first_name: Renaud A.

Confinement effects are considered instrumental at various stages of the origins of life, and life continues to rely on layers of compartmentalization to maintain an out-of-equilibrium state and efficiently synthesize complex biomolecules under mild conditions. As interest in synthetic confined systems grows, we are realizing that the principles governing reactivity under confinement are the same in abiological systems as they are in nature. In this Review, we categorize the ways in which nanoconfinement effects impact chemical reactivity in synthetic systems. Under nanoconfinement, chemical properties can be modulated to increase reaction rates, enhance selectivity and stabilize reactive species. Confinement effects also lead to changes in physical properties. The fluorescence of light emitters, the colours of dyes and electronic communication between electroactive species can all be tuned under confinement. Within each of these categories, we elucidate design principles and strategies that are widely applicable across a range of confined systems, specifically highlighting examples of different nanocompartments that influence reactivity in similar ways. article_processing_charge: No article_type: original author: - first_name: Angela B. full_name: Grommet, Angela B. last_name: Grommet - first_name: Moran full_name: Feller, Moran last_name: Feller - first_name: Rafal full_name: Klajn, Rafal id: 8e84690e-1e48-11ed-a02b-a1e6fb8bb53b last_name: Klajn citation: ama: Grommet AB, Feller M, Klajn R.

These observations have opened up the possibility of attosecond metrology in solids, which would benefit from a precise measurement of the emission times of individual harmonics with respect to the NIR laser field. Here we show that, when high-harmonics are detected from the input surface of a magnesium oxide crystal, a bichromatic probing of the XUV emission shows a clear synchronization largely consistent with a semiclassical model of electron–hole recollisions in bulk solids. On the other hand, the bichromatic spectrogram of harmonics originating from the exit surface of the 200 μm-thick crystal is strongly modified, indicating the influence of laser field distortions during propagation. Our tracking of sub-cycle electron and hole re-collisions at XUV energies is relevant to the development of solid-state sources of attosecond pulses. article_number: '144003' article_processing_charge: No article_type: original arxiv: 1 author: - first_name: Giulio full_name: Vampa, Giulio last_name: Vampa - first_name: Jian full_name: Lu, Jian last_name: Lu - first_name: Yong Sing full_name: You, Yong Sing last_name: You - first_name: Denitsa Rangelova full_name: Baykusheva, Denitsa Rangelova id: 71b4d059-2a03-11ee-914d-dfa3beed6530 last_name: Baykusheva - first_name: Mengxi full_name: Wu, Mengxi last_name: Wu - first_name: Hanzhe full_name: Liu, Hanzhe last_name: Liu - first_name: Kenneth J full_name: Schafer, Kenneth J last_name: Schafer - first_name: Mette B full_name: Gaarde, Mette B last_name: Gaarde - first_name: David A full_name: Reis, David A last_name: Reis - first_name: Shambhu full_name: Ghimire, Shambhu last_name: Ghimire citation: ama: 'Vampa G, Lu J, You YS, et al.

However, a major hurdle to studying large proteins by solid‐state NMR spectroscopy is related to spectral complexity and resonance overlap, which increase with molecular weight and severely hamper the assignment process. Here the use of two sets of experiments is shown to expand the tool kit of 1H‐detected assignment approaches, which correlate a given amide pair either to the two adjacent CO–CA pairs (4D hCOCANH/hCOCAcoNH), or to the amide 1H of the neighboring residue (3D HcocaNH/HcacoNH, which can be extended to 5D). The experiments are based on efficient coherence transfers between backbone atoms using INEPT transfers between carbons and cross‐polarization for heteronuclear transfers. The utility of these experiments is exemplified with application to assemblies of deuterated, fully amide‐protonated proteins from approximately 20 to 60 kDa monomer, at magic‐angle spinning (MAS) frequencies from approximately 40 to 55 kHz. These experiments will also be applicable to protonated proteins at higher MAS frequencies. The resonance assignment of a domain within the 50.4 kDa bacteriophage T5 tube protein pb6 is reported, and this is compared to NMR assignments of the isolated domain in solution. This comparison reveals contacts of this domain to the core of the polymeric tail tube assembly. article_processing_charge: No article_type: original author: - first_name: Hugo full_name: Fraga, Hugo last_name: Fraga - first_name: Charles‐Adrien full_name: Arnaud, Charles‐Adrien last_name: Arnaud - first_name: Diego F. full_name: Gauto, Diego F. last_name: Gauto - first_name: Maxime full_name: Audin, Maxime last_name: Audin - first_name: Vilius full_name: Kurauskas, Vilius last_name: Kurauskas - first_name: Pavel full_name: Macek, Pavel last_name: Macek - first_name: Carsten full_name: Krichel, Carsten last_name: Krichel - first_name: Jia‐Ying full_name: Guan, Jia‐Ying last_name: Guan - first_name: Jerome full_name: Boisbouvier, Jerome last_name: Boisbouvier - first_name: Remco full_name: Sprangers, Remco last_name: Sprangers - first_name: Cécile full_name: Breyton, Cécile last_name: Breyton - first_name: Paul full_name: Schanda, Paul id: 7B541462-FAF6-11E9-A490-E8DFE5697425 last_name: Schanda orcid: 0000-0002-9350-7606 citation: ama: Fraga H, Arnaud C, Gauto DF, et al.

Such studies have invariably involved the use of spectral filters or spectrally dispersive optical components that are inherently lossy and technically complex. Here we present a new technique for the spectral selection of near-threshold harmonics and their spatial separation from the driving beams without any optical elements. We discover the existence of a narrow phase-matching gate resulting from the combination of the non-collinear generation geometry in an extended medium, atomic resonances and absorption. Our technique offers a filter contrast of up to 104 for the selected harmonics against the adjacent ones and offers multiple temporally synchronized beamlets in a single unified scheme. We demonstrate the selective generation of 133, 80 or 56 nm femtosecond pulses from a 400-nm driver, which is specific to the target gas. These results open new pathways towards phase-sensitive multi-pulse spectroscopy in the vacuum- and extreme-ultraviolet, and frequency-selective output coupling from enhancement cavities. article_processing_charge: No article_type: original author: - first_name: Rajendran full_name: Rajeev, Rajendran last_name: Rajeev - first_name: Johannes full_name: Hellwagner, Johannes last_name: Hellwagner - first_name: Anne full_name: Schumacher, Anne last_name: Schumacher - first_name: Inga full_name: Jordan, Inga last_name: Jordan - first_name: Martin full_name: Huppert, Martin last_name: Huppert - first_name: Andres full_name: Tehlar, Andres last_name: Tehlar - first_name: Bhargava Ram full_name: Niraghatam, Bhargava Ram last_name: Niraghatam - first_name: Denitsa Rangelova full_name: Baykusheva, Denitsa Rangelova id: 71b4d059-2a03-11ee-914d-dfa3beed6530 last_name: Baykusheva - first_name: 'Nan' full_name: Lin, Nan last_name: Lin - first_name: Aaron full_name: von Conta, Aaron last_name: von Conta - first_name: Hans Jakob full_name: Wörner, Hans Jakob last_name: Wörner citation: ama: 'Rajeev R, Hellwagner J, Schumacher A, et al.

Although such confined spaces can be found in various nanostructured materials, such as zeolites, nanoporous organic frameworks and colloidal nanocrystal assemblies, the slow diffusion of molecules in and out of these materials has greatly hampered studying the effect of confinement on their physicochemical properties. Here, we show that this diffusion limitation can be overcome by reversibly creating and destroying confined environments by means of ultraviolet and visible light irradiation. We use colloidal nanocrystals functionalized with light-responsive ligands that readily self-assemble and trap various molecules from the surrounding bulk solution. Once trapped, these molecules can undergo chemical reactions with increased rates and with stereoselectivities significantly different from those in bulk solution. Illumination with visible light disassembles these nanoflasks, releasing the product in solution and thereby establishes a catalytic cycle. These dynamic nanoflasks can be useful for studying chemical reactivities in confined environments and for synthesizing molecules that are otherwise hard to achieve in bulk solution. article_processing_charge: No article_type: original author: - first_name: Hui full_name: Zhao, Hui last_name: Zhao - first_name: Soumyo full_name: Sen, Soumyo last_name: Sen - first_name: T. full_name: Udayabhaskararao, T. last_name: Udayabhaskararao - first_name: Michał full_name: Sawczyk, Michał last_name: Sawczyk - first_name: Kristina full_name: Kučanda, Kristina last_name: Kučanda - first_name: Debasish full_name: Manna, Debasish last_name: Manna - first_name: Pintu K. full_name: Kundu, Pintu K. last_name: Kundu - first_name: Ji-Woong full_name: Lee, Ji-Woong last_name: Lee - first_name: Petr full_name: Král, Petr last_name: Král - first_name: Rafal full_name: Klajn, Rafal id: 8e84690e-1e48-11ed-a02b-a1e6fb8bb53b last_name: Klajn citation: ama: Zhao H, Sen S, Udayabhaskararao T, et al.

Recently, choosing the nitric oxide molecule as an example, we have introduced and demonstrated an experimental approach to measure coupled valence electronic and rotational wave packets using high-order-harmonic-generation (HHG) spectroscopy [Kraus et al., Phys. Rev. Lett. 111, 243005 (2013)]. A short outline of the theory to describe the combination of the pump and HHG probe process was published together with an extensive discussion of experimental results [Baykusheva et al., Faraday Discuss. 171, 113 (2014)]. The comparison of theory and experiment showed good agreement on a quantitative level. Here, we present the theory in detail, which is based on a generalized density-matrix approach that describes the pump process and the subsequent probing of the wave packets by a semiclassical quantitative rescattering approach. An in-depth analysis of the different Raman scattering contributions to the creation of the coupled rotational and electronic spin-orbit wave packets is made. We present results for parallel and perpendicular linear polarizations of the pump and probe laser pulses. Furthermore, an analysis of the combined rotational-electronic density matrix in terms of irreducible components is presented that facilitates interpretation of the results. article_number: '023421' article_processing_charge: No article_type: original arxiv: 1 author: - first_name: Song Bin full_name: Zhang, Song Bin last_name: Zhang - first_name: Denitsa Rangelova full_name: Baykusheva, Denitsa Rangelova id: 71b4d059-2a03-11ee-914d-dfa3beed6530 last_name: Baykusheva - first_name: Peter M. full_name: Kraus, Peter M. last_name: Kraus - first_name: Hans Jakob full_name: Wörner, Hans Jakob last_name: Wörner - first_name: Nina full_name: Rohringer, Nina last_name: Rohringer citation: ama: Zhang SB, Baykusheva DR, Kraus PM, Wörner HJ, Rohringer N.

Carbon monoxide molecules are oriented by combining one-colour and delayed two-colour non-resonant femtosecond laser pulses. High-harmonic generation is used to probe the oriented wave-packet dynamics and reveals that a very high degree of orientation (Nup/Ntotal = 0.73–0.82) is achieved. We further extend this approach to orienting carbonyl sulphide molecules. We show that the present two-pulse scheme selectively enhances orientation created by the hyperpolarizability interaction whereas the ionization-depletion mechanism plays no role. We further control and optimize orientation through the delay between the one- and two-colour pump pulses. Finally, we demonstrate a complementary encoding of electronic-structure features, such as shape resonances, in the even- and odd-harmonic spectrum. The achieved progress makes two-pulse field-free orientation an attractive tool for a broad class of time-resolved measurements. article_number: '124030' article_processing_charge: No article_type: original arxiv: 1 author: - first_name: P M full_name: Kraus, P M last_name: Kraus - first_name: Denitsa Rangelova full_name: Baykusheva, Denitsa Rangelova id: 71b4d059-2a03-11ee-914d-dfa3beed6530 last_name: Baykusheva - first_name: H J full_name: Wörner, H J last_name: Wörner citation: ama: 'Kraus PM, Baykusheva DR, Wörner HJ.
