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.

This review summarizes recent theoretical and experimental advancements in using Rydberg atom systems to study non-Hermitian many-body physics, focusing on how their unique interactions and dissipation mechanisms enable the exploration of exceptional points, symmetry breaking, and topological phases.
This paper investigates the non-Markovian decoherence dynamics of a dressed qubit coupled to phonon baths, demonstrating that memory effects and coherence revivals emerge differently depending on the bath's spectral density and the strength of the coupling.
By implementing a novel energy-resolved scheme to prepare narrow atomic matter waves, the researchers achieved the first direct and model-independent observation of the three-dimensional Anderson transition in a disordered potential, resolving long-standing discrepancies between previous experiments and theory.
The researchers demonstrate the first experimental realization of a bound state in the continuum (BIC) in ultracold Li atoms by using Floquet engineering to induce destructive interference between two Feshbach resonances, effectively decoupling a molecular state from the scattering continuum.
This paper develops a variational method to construct a second-quantized Hamiltonian for interacting surface systems with higher-form symmetries, deriving a functional Schrödinger equation that describes both gapless -form fields and massive topological phases with anyonic excitations.
The paper investigates the out-of-equilibrium dynamics of an attractive impurity in a one-dimensional Bose gas, discovering that fast, heavy impurities can form a long-lived, dynamically entangled oscillating state characterized by undamped velocity oscillations caused by a transiently localized boson depletion cloud.
This paper establishes a rigorous microscopic foundation for non-Hermitian renormalization group (RG) methods by deriving them from the invariance of scattering amplitudes in few-body systems, providing a unified framework that links quantum measurement effects to phenomena in both high-energy and atomic physics, such as nuclear scale anomalies and halo nuclei structures.
The W-SLDA Toolkit is a high-performance, GPU-accelerated software package designed for simulating ultracold Fermi gases and superconductors across various dimensions and regimes using density functional theory and Bogoliubov-de Gennes equations.
