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.

Below are the latest papers from arXiv in Cond-Mat — Quant-Gas, freshly summarized and ready for you to explore.

Control, competition and coexistence of effective magnetic orders by interactions in Bose-Einstein condensates with high-Q cavities

This paper theoretically demonstrates that atomic many-body interactions, combined with cavity-induced effects and tunable light-field geometries, enable precise control over the competition and coexistence of diverse magnetic ordering configurations in spinor Bose-Einstein condensates, offering a versatile platform for analog quantum simulation of magnetic materials.

Probing supersolidity through excitations in a spin-orbit-coupled Bose-Einstein condensate

This paper demonstrates the direct observation of both superfluid and crystal excitations in a spin-orbit-coupled Bose-Einstein condensate, thereby confirming its supersolid nature and identifying the transition point through the frequency softening of a stripe compression mode.

Structural Dynamics and Strong Correlations in Dynamical Quantum Optical Lattices

This paper investigates the interplay between superradiant self-organization and superfluid-Mott insulator transitions in ultracold bosonic atoms within a blue-detuned optical cavity, revealing light-driven structural phase transitions and mode softening at critical points without requiring higher energy bands.

Observation of Magnon-Polarons in the Fermi-Hubbard Model

Using Raman excitation in a cold atom Fermi-Hubbard system, researchers observed a new quasiparticle called a magnon-Fermi-polaron, formed by the dressing of magnons with doped holes, and characterized its momentum-dependent energy shifts and spectral weight reduction as a function of doping.

Origin and emergent features of many-body dynamical localization

This paper resolves the long-standing debate on whether interactions break dynamical localization in quantum kicked rotor systems by introducing an extended mapping from the kicked Lieb-Liniger model to a high-dimensional lattice, which reveals universal features like hybrid exponential-algebraic decay couplings and explains the emergence of many-body dynamical localization in strongly correlated quantum gases.

Interferometric Braiding of Anyons in Chern Insulators

This paper proposes a Ramsey interferometry protocol using addressable impurities to coherently control and braid anyons in fractional Chern insulators, enabling the unambiguous separation and measurement of Aharonov-Bohm and exchange geometric phases for direct experimental verification of anyonic statistics.

Spectroscopic readout of chiral photonic topology in a single-cavity spin-orbit-coupled Bose-Einstein condensate

This paper proposes and demonstrates a framework for spectroscopically detecting chiral photonic topology in a single-cavity spin-orbit-coupled Bose-Einstein condensate by using cavity transmission power spectral density as a direct proxy for momentum- and frequency-resolved photonic Chern markers, thereby enabling the identification of topological phases and exceptional points without requiring bulk-band tomography.

Temperature effect on a kicked Tonks-Girardeau gas

This paper demonstrates that many-body dynamical localization in a kicked Tonks-Girardeau gas persists even at high finite temperatures, albeit with degraded coherence and modified thermalization, while also revealing a localization-delocalization transition at intermediate temperatures.

Tuning interactions between static-field-shielded polar molecules with microwaves

This paper proposes and validates a general method to widely tune the interactions between static-field-shielded polar molecules by applying a microwave field, enabling control over both s-wave scattering lengths and dipole lengths while maintaining strong suppression of collisional losses.

Order in the interference of a long chain of Bose condensates with unrestricted phases

This paper demonstrates that a long chain of Bose condensates with unrestricted phases exhibits distinct spatial interference orders depending on phase relationships, where equal phases produce the Talbot effect while random or disordered phases generate qualitatively different fringe evolution, offering a method to measure inter-condensate coherence and correlation length.
