cond-mat.quant-gas papers

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.

On Gist.Science, we process every new preprint in this field directly from arXiv to make these complex discoveries accessible to everyone. Our team provides both plain-language overviews for the curious mind and detailed technical summaries for experts, ensuring you get the full picture without getting lost in the jargon. Below are the latest papers from arXiv in Cond-Mat — Quant-Gas, freshly summarized and ready for you to explore.

An elementary proof of symmetrization postulate in quantum mechanics for a system of particles

This paper provides a mathematical justification for the symmetrization postulate in three-dimensional quantum mechanics by demonstrating that, for a system of N identical particles with a continuous wave function and an exchange-invariant potential on a connected configuration space, the requirement of time-invariant probability density under particle exchange necessitates that the wave function be either totally symmetric or totally antisymmetric.

Nonthermal Dynamics and Scar-Like Spectral Structures in a High-Spin Fermi Gas

Using time-dependent Hartree-Fock simulations, this study reveals that a harmonically trapped spin-3/2 Fermi gas exhibits weak ergodicity breaking and long-lived coherent oscillations driven by a quasi-regular, spectrally stable manifold rather than conventional eigenstate-dominated quantum scars.

Reproducible nucleation and control of stable quantum vortex rings in Bose-Einstein condensates

This paper proposes and numerically validates an experimentally feasible protocol for the deterministic nucleation and manipulation of stable quantum vortex rings in Bose-Einstein condensates using a sweeping laser-sheet barrier, enabling precise control over their properties and the generation of Kelvin-wave excitations for the study of three-dimensional vortices and quantum turbulence.

Equilibrium Partition Function of Non-Relativistic CFTs in Harmonic Trap

This paper investigates the equilibrium partition function of non-relativistic conformal field theories in harmonic traps, revealing that the logarithm of the partition function exhibits universal simple poles in the difference between the squared trapping frequency and squared angular velocities, with residues determined by the equation of state in the hydrodynamic regime and by specific thermodynamic variables in the large-angular-momentum limit.

Stability of flat-band Bose-Einstein condensation from the geometry of compact localized states

This paper reformulates the stability of flat-band Bose-Einstein condensation as a Euclidean geometry problem using compact localized states, demonstrating that triangular frameworks with nonzero area support condensation while square frameworks do not, thereby offering new design principles for stable flat-band condensates.

Soliton resuscitations: asymmetric revivals of the breathing mode of an atomic bright soliton in a harmonic trap

This paper explains the asymmetric pattern of breathing mode revivals in a harmonically trapped atomic bright soliton, where emitted atoms return to interfere with the soliton in a non-Markovian environment, by deriving an analytical approximation to the system's Bogoliubov-de Gennes frequency spectrum.

Bose-Einstein Condensation, Fluctuations and Spontaneous Symmetry Breaking

This paper challenges the traditional view that macroscopic fluctuations and spontaneous symmetry breaking are incompatible in Bose-Einstein condensation by proposing an alternative framework for the uniform ideal gas where the standard Bogoliubov quasi-average fails, and the observed phenomena are explained through the condensation of fluctuations and long-range correlations.

Short-wavelength mesophases in the ground states of core-softened particles in two-dimensions

This study combines variational analysis and molecular dynamics simulations to map the ground-state phase diagram of two-dimensional core-softened particles, revealing a rich landscape of cluster lattices, Bravais structures, and frustration-induced quasicrystals driven by competing length scales.

Quantum Droplets of Light in Semiconductor Microcavities

This paper predicts the existence of self-bound quantum droplets formed by a spin mixture of exciton-polaritons in atomically thin semiconductor microcavities, where tunable interactions near a biexciton Feshbach resonance balance mean-field attraction with quantum fluctuation-induced repulsion.
