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 investigates homogeneous nuclear matter using an \textit{ab initio} Self-consistent Green's function approach based on chiral effective field theory, demonstrating strong agreement with coupled-cluster theory for the equation of state while providing detailed insights into single-particle properties and dynamics.
This paper presents a comprehensive mean-field analysis of a transversely pumped Bose-Einstein condensate in a red-detuned cavity, mapping out its steady-state phase diagram and characterizing complex dynamical behaviors—including bistability, chaos, and resonance-driven instabilities—that emerge beyond the simplified Dicke model approximation.
This paper theoretically demonstrates that altermagnetic order in a weakly interacting two-component Bose-Einstein condensate induces distinct anisotropic features in low-energy excitations and response functions, which vanish upon angular averaging, while also calculating the corresponding Lee-Huang-Yang correction to the ground-state energy.
This study employs the Gaussian Expansion Method to investigate trions in two-dimensional transition metal dichalcogenide monolayers, successfully benchmarking states against existing methods and predicting a novel bound trion state while analyzing the effects of strain and dielectric environments on their properties.
This paper demonstrates that coherent three-body recombination transforms the standard second-order phase transition in atom-molecule Bose-Einstein condensates into a first-order transition characterized by a double-well free energy landscape, bistability, and entanglement, thereby establishing it as a powerful tool for quantum state engineering.
This paper theoretically demonstrates that stationary Fano coherence can be achieved in a V-type three-level quantum system driven by polarized incoherent radiation without requiring degenerate excited levels, thereby establishing a robust resource for coherence-enhanced energy conversion while outlining the experimental challenges of implementing this model with Rubidium atoms.
This paper proposes a feasible experimental scheme using periodically driven ultracold atoms in a 3D optical Raman lattice to realize unpaired Weyl points with tunable net chirality, thereby circumventing the Nielsen-Ninomiya theorem and enabling the observation of the chiral magnetic effect through a quantized charge current.
This paper rigorously derives the momentum distribution of a dilute spin-1/2 Fermi gas for a trial state that accurately captures the ground state energy up to the Huang–Yang formula, confirming Belyakov's earlier formal perturbative predictions.
This paper proposes a protocol for a many-body phase microscope using Fourier-space manipulation in quantum gas microscopes to directly measure off-diagonal correlators, including d-wave superconducting order parameters, spectral functions, and hidden orders in exotic quantum states.
Using a momentum-space transition operator framework with realistic interatomic potentials, this study rigorously calculates the atom-trimer scattering of cold atoms to confirm the existence of a second excited tetramer resonance below the excited trimer threshold, determining its position and width while accounting for significant finite-range effects and nonresonant partial wave contributions.
