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 demonstrates that introducing a tunable phase in collective light-matter coupling creates a phase-dependent strong symmetry in the Liouvillian, enabling precise control over dissipative phase transitions and significantly lowering the critical driving strength required for dynamical changes in cavity QED systems.
This paper investigates how sharp corners on finite-size rectangular obstacles critically amplify local flow velocity to determine the onset of vortex nucleation in two-dimensional superflows, establishing a theoretical framework that accurately predicts critical velocities for both impenetrable walls and wells in agreement with numerical simulations.
This paper investigates the thermodynamic geometry of relativistic ideal gases across classical and quantum statistics, demonstrating that while the characteristic signs of thermodynamic curvature persist, relativistic effects introduce mass-dependent shifts in curvature singularities and corrections to the Bose-Einstein condensation temperature.
This paper reports the first high-resolution spectroscopy of over 700 Rydberg states in 162Dy, achieving a tenfold improvement in the precision of its ionization potential and utilizing multichannel quantum defect theory to characterize perturbing states, thereby establishing a foundation for dysprosium-based quantum architectures and benchmarks for ab-initio calculations.
This paper presents a new imaging technique that enables rapid, high-fidelity, state-resolved detection of up to four quantum states in a single fermionic strontium atom, overcoming a key challenge for advancing qudit-based quantum computing and SU(N) quantum simulations.
This paper employs numerical methods combining quantum hydrodynamics and Hartree-Fock models to demonstrate that self-bound three-dimensional Bose-Fermi droplets can exist at nonzero temperatures in both free space and box potentials, with their stability and properties governed by interspecies attraction strength, total atom number, and initial condensate fraction.
This paper demonstrates that incorporating long-range interactions in an extended XY spin-1/2 chain significantly enhances the efficiency, fidelity, and speed of quantum state transfer compared to short-range models, particularly by mitigating size-dependent performance degradation and identifying optimal parameter regimes.
This paper reformulates the canonical-ensemble description of reactive quantum gas mixtures by replacing the conventional equality of chemical potentials with a single global particle-number-conservation constraint, thereby naturally incorporating Fermi-Dirac or Bose-Einstein correlations and concentration fluctuations while smoothly reducing to the classical ideal gas limit.
This paper investigates the formation, bistability, and stability of localized modes in a Bose-Einstein condensate within a one-dimensional optical cavity featuring incommensurate potentials and photon-atom interactions, demonstrating how these systems enable matter-wave localization without two-body interactions and can function as XOR logic gates.
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.
