Frustrated Rydberg Atom Arrays Meet Cavity-QED: Emergence of the Superradiant Clock Phase

Using large-scale quantum Monte Carlo simulations, this study reveals that infinite-range light-matter interactions in frustrated Rydberg atom triangular arrays lift ground-state degeneracy to induce a novel superradiant clock phase, replacing fragile classical order-by-disorder with a first-order transition driven by nonzero photon density and nonlocal ring exchange interactions.

Universal Dynamics with Globally Controlled Analog Quantum Simulators

This paper establishes the theoretical universality of analog quantum simulators under global control, introduces a direct quantum optimal control framework to synthesize complex effective Hamiltonians, and experimentally demonstrates the engineering of three-body interactions and topological dynamics on a Rydberg-atom array.

Cold-Atom Buoy: A Differential Magnetic Sensing Technique in Cold Quadrupole Traps

This paper presents a differential magnetic sensing technique using a cold-atom cloud in a magnetic quadrupole trap, which achieves milli-Gauss resolution by measuring the displacement of the trap center under field reversal to cancel common-mode noise without requiring spectroscopic interrogation.

Realizing the Emery Model in Optical Lattices for Quantum Simulation of Cuprates and Nickelates

This paper proposes a quantum simulation scheme using ultracold atoms in optical lattices to realize the three-band Emery model, enabling the study of high-temperature superconductivity in cuprates and nickelates on system sizes that are currently inaccessible to numerical methods.

Digital dissipative state preparation for frustration-free gapless quantum systems

This paper introduces a fully digital protocol utilizing local projective measurements and unitary feedback to efficiently prepare algebraically correlated, a priori unknown ground states of frustration-free gapless quantum systems, with performance verified across various models and shown to reveal universal critical properties through transient cooling dynamics.

Lee-Huang-Yang dynamics emergent from a direct Wigner representation

This paper demonstrates that the truncated Wigner approach can naturally incorporate Lee-Huang-Yang corrections for ultracold Bose gases by tailoring bare interaction parameters, thereby capturing quantum fluctuation effects and correlation dynamics that standard mean-field and extended Gross-Pitaevskii equation formulations fail to describe, particularly in regimes of strong interaction.

Tomographic collective modes in a magnetic field

This paper investigates the transition from tomographic to conventional transport in two-dimensional Fermi liquids under a magnetic field by using a numerically exact solution of the linearized Boltzmann equation to demonstrate that a critical magnetic field causes one of two diffusive tomographic collective modes to disappear, leaving a remaining mode that becomes increasingly hydrodynamic at higher fields.

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.

An efficient and accurate numerical method for computing the ground states of three-dimensional rotating dipolar Bose-Einstein condensates under strongly anisotropic trap

This paper proposes an efficient, spectrally accurate, and memory-economic numerical method combining a preconditioned conjugate gradient algorithm with an anisotropic truncated kernel method to compute the complex ground states of three-dimensional rotating dipolar Bose-Einstein condensates under strongly anisotropic traps, successfully addressing challenges like kernel singularities and fast rotation to reveal novel patterns such as bent vortices.

Emergence of the geometric contribution to the superfluid density in the inner crust of neutron stars

This paper clarifies the origin of the geometric contribution to the superfluid density in neutron star inner crusts by deriving its dependence on the pairing gap within a multi-band framework and demonstrating that accounting for corrections to Bogoliubov quasi-particle states, rather than just Hartree-Fock single-particle states, is essential for its emergence.
