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 presents a framework for simulating -dimensional quantum field theories with boundaries in curved spacetimes using open spin systems, demonstrating that by deriving and implementing specific boundary conditions for Majorana fermions, these lattice models accurately reproduce continuum QFT dynamics, spectra, and responses.
This paper develops a self-consistent theoretical framework describing Rydberg electrons orbiting polarizable liquid cores, such as superfluid helium droplets, which breaks angular momentum degeneracy and offers a method to probe droplet properties like crystallization through stimulated electron transitions.
This paper reports the experimental realization of a large-area, multi-loop, and multi-axis atomtronic Sagnac interferometer using Bose-Einstein condensates in an optical waveguide, achieving a record enclosed area of 8.7 mm² and demonstrating high-contrast rotation sensing capabilities across multiple arbitrary axes.
This paper investigates 1D fermionic superradiance in optical lattices, revealing novel tricritical phenomena and multistability arising from higher-order Fermi surface nesting that distinguish 1D from 2D systems and offer new insights into the relationship between quantum and classical phase transitions.
This paper demonstrates that isotropic three-dimensional Fermi liquids exhibit a hierarchy of long-lived, non-hydrodynamic modes where odd-parity relaxation is significantly slower than even-parity relaxation due to Pauli blocking and interaction effects, a phenomenon previously thought unique to two dimensions.
This paper introduces an efficient equilibrium quantum Monte Carlo framework that leverages energy conservation and self-thermalization to map the finite-temperature dynamical phase diagram of the D quantum Ising model, revealing unexpected cooling effects and ferromagnetic transitions from paramagnetic states without explicitly simulating unitary time evolution.
This paper identifies a generic singularity in the equal-time three-point density correlations of two-dimensional Fermi liquids, demonstrating that its coefficient is determined by the quantized Euler characteristic in non-interacting systems and renormalized by Landau parameters in interacting ones, thereby implying long-range real-space correlations favoring collinear configurations.
This paper demonstrates that generalized boundary conditions with complex hopping amplitudes in the Hatano-Nelson model can be precisely tuned to control the non-Hermitian skin effect, determine the emergence of exceptional points, and dictate whether the energy spectrum remains real or becomes complex.
This paper demonstrates that dissipation, typically viewed as a detrimental source of decoherence, can be harnessed as a resource in a Bose-Josephson junction to engineer distinct dynamical phases—including synchronization, coherence recovery, and controlled chaos—thereby enabling the manipulation of quantum coherence and the duration of information scrambling.
This paper establishes and numerically verifies sufficient conditions for a one-to-one correspondence between stationary states of a Bose-Einstein condensate in a one-dimensional quasiperiodic lattice and bi-infinite sequences over a finite alphabet, thereby providing a coding framework to describe these states.
