--- _id: '15053' abstract: - lang: eng text: Atom-based quantum simulators have had many successes in tackling challenging quantum many-body problems, owing to the precise and dynamical control that they provide over the systems' parameters. 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. 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.

In recent years, various studies have proposed analogies to directed percolation, a well-known universality class in statistical mechanics, which describes a non-equilibrium phase transition from a fluctuating active phase into an absorbing state. It is this unlikely relation between the multiscale, high-dimensional dynamics that signify the transition process in virtually all flows of practical relevance, and the arguably most basic non-equilibrium phase transition, that so far has mainly been the subject of model studies, which I review in this Perspective. article_processing_charge: No article_type: original author: - first_name: Björn full_name: Hof, Björn id: 3A374330-F248-11E8-B48F-1D18A9856A87 last_name: Hof orcid: 0000-0003-2057-2754 citation: ama: Hof B.

To explain their origin, it is necessary to study how electromagnetic fields interact with these systems. We address this problem here by studying two classical quantities: Faraday rotation and the complex refractive index in a paradigmatic perovskite CH3NH3PbBr3 in a broad wavelength range. We find that the minimal coupling of electromagnetic fields to the k⋅p Hamiltonian is insufficient to describe the observed data even on the qualitative level. To amend this, we demonstrate that there exists a relevant atomic-level coupling between electromagnetic fields and the spin degree of freedom. This spin-electric coupling allows for quantitative description of a number of previous as well as present experimental data. In particular, we use it here to show that the Faraday effect in lead halide perovskites is dominated by the Zeeman splitting of the energy levels and has a substantial beyond-Becquerel contribution. Finally, we present general symmetry-based phenomenological arguments that in the low-energy limit our effective model includes all basis coupling terms to the electromagnetic field in the linear order.' article_number: '106901' article_processing_charge: No article_type: original author: - first_name: Artem full_name: Volosniev, Artem id: 37D278BC-F248-11E8-B48F-1D18A9856A87 last_name: Volosniev orcid: 0000-0003-0393-5525 - first_name: Abhishek full_name: Shiva Kumar, Abhishek id: 5e9a6931-eb97-11eb-a6c2-e96f7058d77a last_name: Shiva Kumar - first_name: Dusan full_name: Lorenc, Dusan id: 40D8A3E6-F248-11E8-B48F-1D18A9856A87 last_name: Lorenc - first_name: Younes full_name: Ashourishokri, Younes id: e32c111f-f6e0-11ea-865d-eb955baea334 last_name: Ashourishokri - first_name: Ayan A. full_name: Zhumekenov, Ayan A. last_name: Zhumekenov - first_name: Osman M. full_name: Bakr, Osman M. last_name: Bakr - first_name: Mikhail full_name: Lemeshko, Mikhail id: 37CB05FA-F248-11E8-B48F-1D18A9856A87 last_name: Lemeshko orcid: 0000-0002-6990-7802 - first_name: Zhanybek full_name: Alpichshev, Zhanybek id: 45E67A2A-F248-11E8-B48F-1D18A9856A87 last_name: Alpichshev orcid: 0000-0002-7183-5203 citation: ama: Volosniev A, Shiva Kumar A, Lorenc D, et al.

However, to what extent the properties of such supramolecular crystals actually resemble those of atomic materials often remains unclear. Here, we present coarse-grained molecular simulations explicitly demonstrating how a behavior evocative of that of semiconductors may emerge in a colloidal superlattice. As a case study, we focus on gold nanoparticles bearing positively charged groups that self-assemble into FCC crystals via mediation by citrate counterions. In silico ohmic experiments show how the dynamically diverse behavior of the ions in different superlattice domains allows the opening of conductive ionic gates above certain levels of applied electric fields. The observed binary conductive/nonconductive behavior is reminiscent of that of conventional semiconductors, while, at a supramolecular level, crossing the “band gap” requires a sufficient electrostatic stimulus to break the intermolecular interactions and make ions diffuse throughout the superlattice’s cavities. article_processing_charge: No article_type: original author: - first_name: Chiara full_name: Lionello, Chiara last_name: Lionello - first_name: Claudio full_name: Perego, Claudio last_name: Perego - first_name: Andrea full_name: Gardin, Andrea last_name: Gardin - first_name: Rafal full_name: Klajn, Rafal id: 8e84690e-1e48-11ed-a02b-a1e6fb8bb53b last_name: Klajn - first_name: Giovanni M. full_name: Pavan, Giovanni M. last_name: Pavan citation: ama: Lionello C, Perego C, Gardin A, Klajn R, Pavan GM.

However, precise control over the oxidation and reduction effects in PEDOT:PSS remains a challenge, which greatly sacrifices both S and σ. Here, we propose a two-step post-treatment using a mixture of ethylene glycol (EG) and Arginine (Arg) and sulfuric acid (H2SO4) in sequence to engineer high-performance PEDOT:PSS thermoelectric films. The high-polarity EG dopant removes the excess non-ionized PSS and induces benzenoid-to-quinoid conformational change in the PEDOT:PSS films. In particular, basic amino acid Arg tunes the oxidation level of PEDOT:PSS and prevents the films from over-oxidation during H2SO4 post-treatment, leading to increased S. The following H2SO4 post-treatment further induces highly orientated lamellar stacking microstructures to increase σ, yielding a maximum power factor of 170.6 μW m−1 K−2 at 460 K. Moreover, a novel trigonal-shape thermoelectric device is designed and assembled by the as-prepared PEDOT:PSS films in order to harvest heat via a vertical temperature gradient. An output power density of 33 μW cm−2 is generated at a temperature difference of 40 K, showing the potential application for low-grade wearable electronic devices. acknowledgement: Scientific Research Program Funded by Shaanxi Provincial Education Department (Program No.22JY012), Natural Science Basic Research Program of Shaanxi (Grant No.2022JZ-31), Young Talent fund of University Association for Science and Technology in Shaanxi, China (Grant No.20210411), China Postdoctoral Science Foundation (Grant No. 2021M692621), the Foundation of Shaanxi University of Science & Technology (Grant No. 2017GBJ-03), Open Foundation of Key Laboratory of Auxiliary Chemistry and Technology for Chemical Industry, Ministry of Education, Shaanxi University of Science and Technology (Grant No. KFKT2022-15), and Open Foundation of Shaanxi Collaborative Innovation Center of Industrial Auxiliary Chemistry and Technology, Shaanxi University of Science and Technology (Grant No. KFKT2022-15). article_number: '156101' article_processing_charge: No article_type: original author: - first_name: Li full_name: Zhang, Li last_name: Zhang - first_name: Xingyu full_name: Liu, Xingyu last_name: Liu - first_name: Ting full_name: Wu, Ting last_name: Wu - first_name: Shengduo full_name: Xu, Shengduo id: 12ab8624-4c8a-11ec-9e11-e1ac2438f22f last_name: Xu - first_name: Guoquan full_name: Suo, Guoquan last_name: Suo - first_name: Xiaohui full_name: Ye, Xiaohui last_name: Ye - first_name: Xiaojiang full_name: Hou, Xiaojiang last_name: Hou - first_name: Yanling full_name: Yang, Yanling last_name: Yang - first_name: Qingfeng full_name: Liu, Qingfeng last_name: Liu - first_name: Hongqiang full_name: Wang, Hongqiang last_name: Wang citation: ama: Zhang L, Liu X, Wu T, et al.
