Quantum Statistical Thermal Engine at the BCS-BEC crossover
We propose a quantum heat engine based on a two-component Fermi gas with s-wave contact interaction, operating across the BCS-BEC crossover.Strong-to-Weak Spontaneous Symmetry Breaking of Dephased Fermions
Strong-to-weak spontaneous symmetry breaking (SWSSB) is a novel phase transition in mixed states associated with the loss of global charge information.The Principle of Minimum Justified Correlation
It is shown that Shannon entropy, Fisher information, and quantum-mechanical kinetic energy may all be viewed as measures of correlation.Breakdown of Local Denoising as Semantic Speciation
The dynamics of generative models exhibit two apparently distinct temporal windows: a speciation window, in which a sample commits to a semantic class, and a nonlocality window, in which local…Exact Operator Complexity Measures from Random Matchgate Unitaries
Matchgate circuits describe classically tractable dynamics in a physically relevant setting while nonetheless exhibiting features characteristic of complex quantum systems, such as high amounts of…Collective Dynamics in Spin Chains with Constrained Dissipation: Classically Fragile but Quantum Robust
Collective non-equilibrium phenomena in many-body systems are strongly influenced by fluctuations, particularly in the vicinity of phase transitions, where the interplay between classical and…The equivalence of topological indices for $\mathrm{U}(1)\rtimes\mathbb{Z}_2$-symmetric quantum spin chains
Symmetry-protected topological (SPT) phases in quantum spin chains are distinguished by topological indices.Correlation measure for statistical systems
A measure of correlations for statistical systems is advanced, called correlation index.Optimal performance in a chaotic Floquet quantum battery
We study a quantum battery consisting of $N$ qubits interacting uniformly with each other.Speed-Fisher Information: Chaos and Irreversibility in Classical and Quantum Dynamics
We propose a unified perspective on classical and quantum chaos based on the sensitivity of a system's stationary states to slow driving.Discrete Scale Invariance of Ising Mesons
Discrete scale invariance often arises from resonant few-body or singular scale-invariant dynamics.One-dimensional quantum Gibbs states in constant circuit depth
We prove that the Gibbs state of any spin chain can be exactly decomposed into a mixture of product states over contiguous blocks of qubits with bounded length, at any constant temperature.Characterizing quantum precision enhancement for multiple currents in open quantum systems
The kinetic uncertainty relation (KUR) constrains fluctuations of individual currents in classical nonequilibrium systems in terms of the dynamical activity, which quantifies the average number of…Entanglement spectrum and magic in higher-dimensional free fermionic systems
We study fermionic non-local magic in higher-dimensional free-fermion systems through the lens of the entanglement spectrum.Out-of-Time-Ordered Correlators Beyond Lindblad
Out-of-time-ordered correlators (OTOCs) provide a powerful probe of quantum chaos and scrambling.Collectivity limits quantum entanglement
Understanding what limits many-body quantum entanglement is a central problem in physics.Temperature--Hamiltonian Ambiguity in Strong-Coupling Quantum Equilibrium
Strong coupling generally drives a subsystem away from the Gibbs state of its bare Hamiltonian at the bath temperature.Swapping Quantum Annealing Errors into a Cavity
Quantum annealing is a promising form of quantum computation, but it slows down at a small energy gap $Δ$ during the anneal, and the errors it makes there remain undetected.Escaping Alignment: A Physical Trap Model of Best-of-N Jailbreaking
Best-of-$N$ jailbreaking (BoN) bypasses safeguards of aligned models by drawing $N$ independent augmentations of an unsafe prompt and sampling $M$ completions of each.Genuine Multi-Entropy of Fully Symmetric Gaussian States
We study the tri-partite genuine Rényi multi-entropy of fully symmetric Gaussian states as a function of the squeezing parameter for different total number of bosonic modes under different subsystem…
