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 introduces a novel many-body truncation for Gorkov self-consistent Green's function theory that combines first-order pairing correlations with third-order particle-number-conserving dynamical correlations to accurately predict the equation of state and spectral properties of infinite nuclear matter using modern chiral effective field theory Hamiltonians.
This paper investigates interacting excitons in two-dimensional systems with a moat dispersion, revealing that such band structures can drive statistical transmutation into chiral spin liquids at low densities and stabilize inhomogeneous condensates and supersolid phases at higher densities, even with purely repulsive interactions, suggesting these exotic states are experimentally accessible.
This paper demonstrates through numerical simulations and variational analysis that critical fluctuations near an Ising transition in a two-dimensional spin-orbit coupled Bose gas can drive vortex deconfinement, leading to a Berezinskii-Kosterlitz-Thouless transition and a first-order phase change.
This paper demonstrates that interacting anyonic chains exhibit anomalous dynamical scaling characterized by superdiffusive density correlations and ballistic entanglement growth, revealing a distinct universal nonequilibrium behavior driven by fractional statistics that separates particle transport from information spreading.
This paper experimentally demonstrates the realization of a synthetic monopole in an ultracold spin-1 ensemble, where tunable spin-tensor coupling is used to engineer field anisotropy, directly measure the topological Chern number, and observe a topological phase transition.
This paper predicts the realization of a temporal Efimov effect in an analog linearly expanding universe created by a quasi-two-dimensional Bose-Einstein condensate, where time-rescaling symmetry induces particle production characterized by log-periodic oscillations that serve as a distinct signature of the effect and map onto cosmological horizon modes.
This paper demonstrates that helicoidal spin-orbit coupling can induce stable, quantized transport of solitons in two-component Bose-Einstein condensates via linear and nonlinear Thouless pumping, with the transport efficiency and stability critically dependent on the Zeeman splitting and the number of atoms.
This paper demonstrates that infinite-range nonlocal interactions in synthetic dimensions can adiabatically transform a Laughlin-type fractional Chern insulator into a charge-ordered Tao-Thouless state without closing the many-body gap, revealing that conventional topological markers remain unchanged despite the loss of locality-protected robustness.
This paper demonstrates that while non-compact zero modes in bosonic systems cause unbounded logarithmic growth of entanglement entropy, compact zero modes in systems like quantum rotors halt this spreading and dephasing, thereby capping entanglement at a finite value and revealing the necessity of compact descriptions for accurately modeling late-time dynamics in ultracold-atom realizations.
This paper demonstrates a scalable optical tweezer platform using holographic metasurfaces to trap over 1,000 single strontium atoms in arbitrary 2D geometries with high uniformity, achieving a record 360,000 traps to enable large-scale quantum applications.
