Direct tests of conformal symmetry with Rydberg atoms: assessment and proposals
We propose a direct test of conformal symmetry using Rydberg-atom arrays.Time-reversal-based quantum metrology in a central-spin architecture: from SATIN to butterfly echo
We investigate quantum-enhanced time-reversal-based metrology using the central spin model, in which a single ancilla spin of magnitude $S_{\rm cen}$ mediates interactions between $N$ bath spins…The often overlooked role of sound in liquid thermal transport
Formulated a hundred years ago, the Bridgman formula for thermal conductivity of liquids postulates a proportionality between sound velocity and thermal conductivity.Realization of a Superleak in a Quantum Gas
Ultracold quantum gases offer a controllable and microscopically accessible platform for understanding and engineering superfluidity.Geometry-controlled zeros of resonant Kelvin-wave conversion in four spatial dimensions
Geometry can suppress leading Kelvin-wave conversion even at exact momentum and frequency resonance.Quantum-Enhanced Matterwave Interferometry in a Ring Waveguide
We propose a quantum-enhanced matter-wave interferometry protocol based on fractional-revival dynamics of a Bose-Einstein condensate in a ring, combined with a controlled interaction quench.Hydrodynamic description of correlation matrix eigenvalues in a finite temperature expanding free fermionic gas
A recent work considered the Page curve for entanglement entropy of a freely expanding one-dimensional Fermi gas starting from a finite box (the system) in a zero-temperature initial state that then…Discrete time liquids
Discrete time crystals exhibit robust subharmonic oscillations, spontaneously breaking the discrete time-translation symmetry of a periodic drive.Systematic Truncated Wigner Approximation for Open Spin Systems Reveals Long-Range Order Far from Equilibrium
Long-range interactions can protect dissipative order against fluctuations, but determining when they do so in two dimensions remains out of reach for existing many-body methods.Fate of Discrete Time Crystals in Finite-Size Cavity QED Systems
It has been shown that Discrete Time Crystal (DTC) behavior may arise in the periodically driven, open Dicke model in the thermodynamic limit ($N \rightarrow \infty$).Computing excited states of dipolar Bose--Einstein condensates by constrained gentlest ascent dynamics
Dipolar Bose--Einstein condensates (BECs), i.e., BECs with long-range dipole-dipole interactions (DDI), exhibit extraordinarily rich physics and serve as a versatile experimental platform for…Dynamics of two bosons with density-assisted tunnelling in a one-dimensional tilted lattice
We investigate the dynamics of two bosons in a tilted one-dimensional optical lattice with both standard and density-assisted tunnelling.Floquet ground state order
Clean, interacting, periodically driven systems are believed to thermalize to featureless, infinite-temperature states that preclude the formation of stable ordered states.Efficient Ground-State Manifold Amplification for Rydberg Atom Arrays via Houdayer Cluster Updates
We demonstrate a hybrid quantum-classical approach for exploring ground-state manifolds of maximum independent set problems, in which quantum hardware supplies the initial solutions and an entirely…Characterizing supersolid phase transitions in trapped quantum gases with tilted dipoles at finite temperature
Motivated by a recent experimental work arXiv:2608.20327, we theoretically investigate the nature of phase transitions in a trapped dipolar quantum gas upon tuning the contact interaction strength…High-order resonances and emergent coherent dynamics in interacting Stark chains
A linear potential gradient can strongly suppress quantum dynamics, while interactions can activate resonant many-body processes whose higher-order structure remains largely unexplored.End-to-End Optimization of Partial Fault Tolerance in Neutral-Atom Arrays
Fault-tolerant (FT) quantum computation offers a pathway to quantum advantage, but its realization is hindered by its significant overhead.Exploring ground state phase diagrams of Rydberg atom arrays with finite projected entangled-pair states
Rydberg atom arrays (RAA) have been advocated as a promising avenue for the quantum simulation of different exotic quantum states.Parallel Omnidirectional Atom Rearrangement with Dynamic Holograms
The ability to assemble and reconfigure individual atoms is central to performing quantum science using optical tweezer arrays.Spectral signatures of hidden order and hidden quantum critical points
Hidden-order phases elude the conventional Ginzburg-Landau framework: although they spontaneously break symmetry, their order remains invisible to standard local two-point correlators.
