Full counting statistics and first-passage times in quantum Markovian processes: Ensemble relations, metastability, and fluctuation theorems
Paul Menczel, Christian Flindt, Fredrik Brange +2
We develop a comprehensive framework for characterizing fluctuations in quantum transport and nonequilibrium thermodynamics using two complementary approaches: full counting statis…
Discrete time crystals detected by time-translation twist
Ryota Nakai, Taozhi Guo, Shinsei Ryu
We introduce a boundary condition twisted by time translation as a novel probe to characterize dynamical phases in periodically driven (Floquet) quantum systems. Inspired by twiste…
Energy diffusion in the long-range interacting spin systems
Hideaki Nishikawa, Keiji Saito
We investigate energy diffusion in long-range interacting spin systems, where the interaction decays algebraically as with the distance between the sites.…
Controlling discrete time crystals via single-site operations in zero-field diamond quantum simulators
Naoya Egawa, Kaoru Mizuta, Joji Nasu
Discrete time crystals (DTCs) have emerged as novel nonequilibrium phases of matter that spontaneously break discrete time-translation symmetry in periodically driven systems. Rigo…
Exact spectral form factors of non-interacting fermions with Dyson statistics
Tatsuhiko N. Ikeda, Lev Vidmar, Michael O. Flynn
The spectral form factor (SFF) is a powerful diagnostic of random matrix behavior in quantum many-body systems. We introduce a family of random circuit ensembles whose SFFs can be…
Single-Particle Universality of the Many-Body Spectral Form Factor
Michael O. Flynn, Lev Vidmar, Tatsuhiko N. Ikeda
We consider systems of fermions evolved by non-interacting unitary circuits with correlated on-site potentials. When these potentials are drawn from the eigenvalue distribution of…
Universal bounds on the performance of information-thermodynamic engine
Tomohiro Tanogami, Tan Van Vu, Keiji Saito
We investigate fundamental limits on the performance of information processing systems from the perspective of information thermodynamics. We first extend the thermodynamic uncerta…
Dissipation, quantum coherence, and asymmetry of finite-time cross-correlations
Tan Van Vu, Van Tuan Vo, Keiji Saito
Recent studies have revealed a deep connection between the asymmetry of cross-correlations and thermodynamic quantities in the short-time limit. In this study, we address the finit…
Geometric characterization for cyclic heat engines far from equilibrium
Tan Van Vu, Keiji Saito
Considerable attention has been devoted to microscopic heat engines in both theoretical and experimental aspects. Notably, the fundamental limits pertaining to power and efficiency…
Key Observable for Linear Thermalization
Yuuya Chiba, Akira Shimizu
For studies on thermalization of an isolated quantum many-body system, the fundamental issue is to determine whether a given system thermalizes or not. However, most studies tested…
Statistical ensembles for phase coexistence states specified by noncommutative additive observables
Yasushi Yoneta, Akira Shimizu
A phase coexistence state cannot be specified uniquely by any intensive parameters, such as the temperature and the magnetic field, because they take the same values over all coexi…
Quantum-inspired search method for low-energy states of classical Ising Hamiltonians
Hiroshi Ueda, Yuichi Otsuka, Seiji Yunoki
We develop a quantum-inspired numerical procedure for searching low-energy states of a classical Hamiltonian composed of two-body fully-connected random Ising interactions and a ra…
