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 develops a universal effective field theory for the low-energy surface oscillations of self-bound superfluid droplets, deriving the normal-mode eigenfrequencies, identifying a critical instability for the breathing mode, and quantizing the resulting ripplons to describe multi-ripplon states in systems like Bose mixtures.
This paper proposes a quantum simulation scheme using ultracold atoms in optical lattices to realize the three-band Emery model, enabling the study of high-temperature superconductivity in cuprates and nickelates on system sizes that are currently inaccessible to numerical methods.
This study investigates the formation and stability of various quasi-one-dimensional solitons in self-repulsive spin-orbit-coupled dipolar Bose-Einstein condensates, revealing that the interplay between spin-orbit coupling strength and interaction parameters dictates the emergence of distinct soliton types (such as bright-bright, dark-bright, and their modulated variants) in both pseudo spin-half and spin-one systems, all of which are demonstrated to be dynamically stable.
This paper introduces a geometric framework based on the -logarithm linearization principle that unifies the density profiles of 1D quantum fluids across interaction regimes—from the ideal Bose gas to the Tonks-Girardeau gas—within a discrete hierarchy and derives a universal sound velocity scaling law linking static geometry to dynamical excitations.
This paper demonstrates that the stability of flat-band superfluidity in two-dimensional systems depends critically on the specific distribution of the quantum metric within the Brillouin zone rather than just its integrated value, revealing that at least three bands are required for stable condensation and that the superfluid weight is significantly influenced by the condensate quantum metric.
This paper reports the quantum simulation of massive relativistic fields in 2+1 dimensions using a two-component Bose-Einstein condensate to encode the sine-Gordon model, successfully demonstrating both tunable relativistic dispersion in the perturbative regime and non-perturbative topological domain walls.
This paper experimentally demonstrates that the universal Family-Vicsek scaling laws, originally established for classical surface growth, also govern the non-equilibrium dynamics of quantum fluctuations in a one-dimensional Bose gas, thereby unifying the understanding of universality across classical and quantum systems.
This paper reports the deterministic experimental realization of breathing magnetic multi-solitons in a two-component Bose gas and demonstrates their controlled fission into fundamental constituents via a localized perturbation, effectively serving as an experimental analog of the inverse scattering transform.
This paper demonstrates that a temporal Berry phase in a clean U(1) nonlinear sigma model induces space-time anisotropic vortex interference, leading to a quasi-disordered phase with short-range spatial order and persistent temporal coherence that shares the essential correlation properties of the disordered Bose Glass phase, thereby suggesting a unified topological origin for glassy behavior in phase-fluctuation-driven superfluid transitions.
This paper investigates interacting waveguide QED systems where the competition between attractive Jaynes-Cummings binding and repulsive Kerr nonlinearities leads to a rich phase diagram featuring Mott-like insulating and superfluid phases in periodic arrays of atomic impurities.
