This category explores the fascinating world of quantum gases, where scientists cool atoms to temperatures near absolute zero to create exotic states of matter. In these extreme conditions, individual atoms begin to behave like a single giant wave, revealing strange quantum effects that are usually hidden in our everyday warm world. These experiments help researchers understand the fundamental rules governing matter and could one day lead to revolutionary new technologies like ultra-precise sensors or quantum computers.

Using the truncated Wigner approximation to study large two-dimensional systems, this paper demonstrates that quantum kinetically constrained dynamics and pronounced relaxation slowdowns persist in dissipative Rydberg gases even in the weakly dissipative regime where coherent and dissipative processes compete.
This paper theoretically demonstrates that shear viscosity in ultracold Fermi gases can be tuned by several orders of magnitude near the Feshbach resonance through the interplay of Drude-like contributions and higher-order vertex corrections, thereby enabling the realization of high Reynolds number turbulent flows for table-top quantum turbulence simulations.
This paper establishes a relativistic field-theoretical framework for self-bound Bose-Einstein condensates by analyzing a nonlinear Klein-Gordon equation with cubic and logarithmic interactions, deriving a generalized Gross-Pitaevskii equation, and demonstrating stable oscillatory quantum droplet configurations through numerical solutions.
This paper proposes an improved quantum-enhanced gravimetry scheme for Bose-Einstein condensates that utilizes a delta-kick focusing technique to increase density and enhance one-axis twisting interactions, thereby achieving spin squeezing that improves phase sensitivity by a factor of approximately 20 over the standard quantum limit and fourfold compared to previous methods.
This paper proposes a Floquet-engineering framework that creates emergent hierarchical symmetries to suppress Hilbert space violations and extend the lifetime of quantum simulations for lattice gauge theories, even when local constraints are imperfectly implemented.
This study reveals that a uniform artificial gauge field in a half-filled three-leg Bose-Hubbard ladder induces an unexpected charge-density-wave phase and reentrant CDW-vortex-CDW transitions, driven by a strong competition between vortex and density-wave orders that defies typical expectations for such bosonic ladder systems.
This paper numerically demonstrates that false-vacuum decay between metastable honeycomb and stripe supersolid phases in a uniform dipolar gas is driven by bubble nucleation whose growth speed is limited by the slowest sound mode, establishing dipolar supersolids as a versatile platform for studying this phenomenon with direct real-space imaging capabilities.
This paper demonstrates that the Schrödinger-Navier-Stokes equation is formally equivalent to the Navier-Stokes-Korteweg equations for capillary fluids, deriving its dispersion relations and proposing its utility for modeling microfluidic systems and quantum simulations of complex flowing matter.
This paper demonstrates that geometrically ordered, spatially extended 2D atom arrays with subwavelength spacing enable a new regime of collective light-matter interaction where photon-mediated interactions drive extensive superradiance and subradiance, revealing their underlying magnetic-like correlations and establishing a programmable platform for dissipative many-body quantum physics.
This paper reports experimental evidence that a laser-driven dense ensemble of Rb atoms emits light with non-Gaussian statistics, characterized by high-order correlations in the steady state despite the absence of first-order coherence.
