Interaction-enabled metal-insulator phase transition in a driven quantum gas
Camilo Cantillano, Karthick Ramanathan, Zekai Chen +6
Particle transport and energy flow are central to a wide range of phenomena in the natural sciences. While interactions generically promote ergodicity and diffusion, quantum interf…
The wave nature of a Mott insulator
Xudong Yu, Chengyang Wu, Wenhan Chen +10
Quantum phases of matter are routinely identified by coherence features, with interference patterns being one of the most directly observable quantities. In lattices, the superflui…
Observing dissipationless flow of an impurity in a strongly repulsive quantum fluid
Milena Horvath, Sudipta Dhar, Elisabeth Wybo +6
The frictionless motion of an object through a fluid medium is commonly viewed as a hallmark of superfluidity. According to Landau, kinematic constraints prohibit superfluid behavi…
Realization of fractional Fermi seas
Yi Zeng, Alvise Bastianello, Sudipta Dhar +7
The Pauli exclusion principle is a cornerstone of quantum physics: it governs the structure of matter. Extensions of this principle, such as Haldane's generalized exclusion statist…
Exotic critical states as fractional Fermi seas in the one-dimensional Bose gas
Alvise Bastianello, Yi Zeng, Sudipta Dhar +7
Critical quantum field theories occupy a central position in modern theoretical physics for their inherent universality stemming from long-range correlations. As an example, the To…
Observing Bethe strings in an attractive Bose gas far from equilibrium
Milena Horvath, Alvise Bastianello, Sudipta Dhar +5
Bethe strings are bound states of constituent particles in a variety of interacting many-body one-dimensional (1D) integrable quantum models relevant to magnetism, nanophysics, col…
Anyonization of bosons in one dimension: an effective swap model
Botao Wang, Amit Vashisht, Yanliang Guo +4
Anyons emerge as elementary excitations in low-dimensional quantum systems and exhibit behavior distinct from bosons or fermions. Previous models of anyons in one dimension (1D) ar…
Anyonization of bosons
Sudipta Dhar, Botao Wang, Milena Horvath +7
Anyons are low-dimensional quasiparticles that obey fractional statistics, hence interpolating between bosons and fermions. In two dimensions, they exist as elementary excitations…
Observation of many-body dynamical localization
Yanliang Guo, Sudipta Dhar, Ang Yang +6
The quantum kicked rotor is a paradigmatic model system in quantum physics. As a driven quantum system, it is used to study the transition from the classical to the quantum world a…
Bose-Einstein condensation of non-ground-state caesium atoms
Milena Horvath, Sudipta Dhar, Arpita Das +5
Bose-Einstein condensates of ultracold atoms serve as low-entropy sources for a multitude of quantum-science applications, ranging from quantum simulation and quantum many-body phy…
Cooling bosons by dimensional reduction
Yanliang Guo, Hepeng Yao, Sudipta Dhar +5
Cold atomic gases provide a remarkable testbed to study the physics of interacting many-body quantum systems. They have started to play a major role as quantum simulators, given th…
Experimental Observation of the 2D-1D Dimensional Crossover in Strongly Interacting Ultracold Bosons
Yanliang Guo, Hepeng Yao, Satwik Ramanjanappa +6
Dimensionality plays an essential role in determining the nature and properties of a physical system. For quantum systems the impact of interactions and fluctuations is enhanced in…
Long distance optical transport of ultracold atoms: A compact setup using a Moiré lens
Govind Unnikrishnan, Charly Beulenkamp, Dechao Zhang +3
We present a compact and robust setup to optically transport ultracold atoms over long distances. Using a focus-tunable Moiré lens that has recently appeared on the market, we demo…
Compact, robust, and spectrally pure diode-laser system with a filtered output and a tunable copy for absolute referencing
Emil Kirilov, Manfred J. Mark, Maximilian Segl +1
We report on a design of a compact laser system composed of an extended cavity diode laser with high passive stability and a pre-filter Fabri-Perot cavity. The laser is frequency s…
Quantum quench in an atomic one-dimensional Ising chain
Florian Meinert, Manfred J. Mark, Emil Kirilov +4
We study non-equilibrium dynamics for an ensemble of tilted one-dimensional atomic Bose-Hubbard chains after a sudden quench to the vicinity of the transition point of the Ising pa…
Feshbach resonances, weakly bound molecular states and coupled-channel potentials for cesium at high magnetic fields
Martin Berninger, Alessandro Zenesini, Bo Huang +6
We explore the scattering properties of ultracold ground-state Cs atoms at magnetic fields between 450 G (45 mT) and 1000 G. We identify 17 new Feshbach resonances, including two v…
