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 paper investigates the bound and scattering properties of two-atom-one-ion systems near a Feshbach resonance, revealing that long-range ionic interactions significantly deviate from universal neutral-atom behavior by suppressing inelastic recombination rates and extending the lifetimes of Efimov states and triatomic molecular ions.
This paper proposes two complementary Rydberg atom simulator approaches—analog Möbius band geometry and digital Kibble-Zurek ramping—to efficiently characterize and experimentally probe emergent fermions in critical quantum many-body systems.
Using single-atom-resolved detection in an interacting lattice Bose gas, researchers experimentally mapped the full non-Gaussian probability distribution of the order parameter across a continuous phase transition, revealing critical scaling in high-order cumulants that aligns with quantum models rather than classical ones.
This paper establishes a minimal hydrodynamic framework demonstrating that exciton diffusivity in 2D semiconductors can become effectively negative due to a dynamical instability arising from the nonequilibrium coupling between slow excitons and fast, inertial electron-hole plasma modes.
This paper demonstrates that linear acceleration breaks the axial symmetry of a dual-ring Bose-Einstein condensate junction, activating multimode Josephson dynamics and enabling a controllable spectroscopic protocol to probe the angular structure and eigenfrequencies of collective Bogoliubov modes.
By leveraging the bijective mapping between dynamical and statistical interactions in a one-dimensional strongly interacting quantum gas, researchers experimentally realized and characterized an anyonic thermodynamic ensemble obeying generalized exclusion statistics, providing the first direct evidence for the generalized Pauli principle through precise measurements of the equation of state and other thermodynamic quantities.
This paper derives the operator product expansion for two operators in a spin-orbit coupled bosonic system, with a specific focus on determining the contact density term that governs the system's universal physics.
The paper introduces atomSmltr, a modular Python package designed to simulate laser cooling in complex magnetic and laser beam geometries, featuring a flexible architecture for constructing experimental setups and validated through benchmarks against standard textbook cases.
Using diffusion quantum Monte Carlo simulations, this study characterizes the phase diagram of a mass-asymmetric one-dimensional electron-hole biwire at zero temperature, revealing that strong correlations drive excitonic quasicondensation even at high densities down to a.u., alongside distinct plasma and Wigner-correlated phases.
This paper provides a comprehensive analysis of post-selection probability and fidelity in a bidirectional teleportation protocol, demonstrating that these metrics can be characterized by standard quantum diagnostics like the Loschmidt echo while revealing the initial-state dependence of fidelity and the stability of post-selection probability in integrable models.
