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 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.
This paper employs a diagrammatic Bogoliubov many-body perturbation theory with low-momentum interactions to calculate the Hartree shift and pairing gap in ultracold Fermi gases, successfully reproducing established weak-coupling corrections and showing reasonable agreement with experimental and quantum Monte-Carlo results near the unitary regime.
This paper introduces a spectroscopic protocol using Rydberg tweezer arrays to emulate scanning tunneling microscopy, enabling the direct real-space imaging and characterization of magnetic polarons and their binding properties within frustrated $tJ$ Hamiltonians.
This paper demonstrates that cyclic interaction changes in an integrable one-dimensional Bose gas drive the system into a novel critical phase characterized by fractional Fermi seas, which exhibit correlation signatures incompatible with conventional Tomonaga-Luttinger liquid behavior.
This paper reports the experimental realization of fractional Fermi seas in an excited one-dimensional Bose gas, where stable states exhibiting Friedel oscillations confirm the existence of exotic quantum states with fractional momentum occupancies predicted by generalized exclusion statistics.
This paper demonstrates that atom-thin arrays of quantum emitters exhibit robust nonlinear responses and generate quantum-correlated steady states with multi-mode squeezing even at arbitrarily weak drive intensities, challenging the classical assumption that weakly driven ensembles lack such effects by leveraging the dominant role of subradiant states.
This paper investigates a dual-reflection interface in the transverse field Ising chain that exhibits a discrete symmetry and hosts robust Majorana strong zero modes, which are explicitly constructed via Jordan-Wigner transformation and proposed for realization on digital quantum hardware.
The paper introduces the Moving Born-Oppenheimer Approximation (MBOA), a mixed quantum-classical framework where fast degrees of freedom adiabatically depend on both the positions and momenta of slow ones, revealing novel dynamics like reflection and mass renormalization while significantly altering the state of fast subsystems across various physical models.
This paper clarifies subtle aspects of coherent-state path integrals in quantum thermodynamics, demonstrating that when properly handled in the continuum limit, they yield results consistent with the canonical Hamiltonian approach across various paradigmatic bosonic and fermionic systems.
This study investigates how mass imbalance influences the formation of stable two- and three-body clusters in a one-dimensional Fermi gas with coexisting - and -wave interactions, revealing that while vacuum three-body states are always more deeply bound than two-body ones, moderate interactions in the medium favor a Cooper trimer phase over pairing, accompanied by competition among different trimer configurations.
