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.

Using the quantum color string model, this paper reveals that the microscopic origin of ubiquitous plaquettes in cuprate stripe LDOS is linked to spinon singlet pairs, while also identifying a particle-hole symmetry breaking effect that causes a shift in longer stripes.
This paper proposes an efficient, high-order compact splitting Fourier spectral method that exactly integrates linear rotation and spin-orbit coupling terms via a novel function mapping to accurately and stably simulate the dynamics of rotating spin-2 Bose-Einstein condensates.
This paper presents a high-flux cold strontium source utilizing a 2D MOT and Zeeman slower that achieves a record loading rate of atoms/s into a 3D MOT, demonstrating compatibility with long-term operation and state-of-the-art quantum experiments while offering the design freely to the community.
This paper proposes that the real-space area enclosed by a localized particle's micromotion during a Floquet period serves as a local bulk indicator for anomalous topological phases, establishing a direct proportionality between this area and the system's winding number to enable detection in disordered or interacting quantum simulations.
This paper theoretically investigates the DC and AC Josephson effects in interaction-asymmetric ultracold Fermi gas junctions across the BCS-BEC crossover, revealing a competition between pair spectral weight and chemical potential that leads to a distinct interaction-biased Riedel peak in the tunneling current.
This paper demonstrates that the fermionic truncated Wigner approximation accurately captures the diffusive relaxation dynamics of interacting two-dimensional fermions in a uniform magnetic field at infinite temperature, revealing that while strong interactions suppress magnetic-field effects, comparable interaction and kinetic energies significantly reduce diffusion in sufficiently large systems.
This paper introduces a scalable "spiral quantum state tomography" scheme that utilizes compressed sensing and spiral measurement patterns to efficiently reconstruct quantum many-body states and measure entanglement properties without requiring the challenging local addressing of individual qubits.
This paper introduces the adiabatic echo protocol, a robust method for preparing entangled many-body quantum states that suppresses static experimental imperfections through dynamically engineered destructive interference, demonstrating its effectiveness across diverse platforms like Ising spin chains and Rydberg atom arrays.
This paper presents the design and characterization of an open-hardware, 19-inch rack-mounted high-power RF amplifier optimized for ultracold atom experiments, delivering 36.5 dBm output across 50–1000 MHz with 40 dB gain, over 35% efficiency, and 0.01 dBm long-term stability.
This paper proposes a robust, time- and wavelength-multiplexed protocol for remote atom-atom entanglement generation using cavity-assisted photon scattering, which achieves a high success rate of and 0.999 fidelity while remaining resilient to operational imperfections and parameter fluctuations.
