Nonequilibrium fluctuation-response relations for state observables
Krzysztof Ptaszynski, Timur Aslyamov, Massimiliano Esposito
Time-integrated state observables, which quantify the fraction of time spent by the system in a specific pool of states, are important in many fields, such as chemical sensing or t…
Critical heat current fluctuations in Curie-Weiss model in and out of equilibrium
Krzysztof Ptaszynski, Massimiliano Esposito
In some models of nonequilibrium phase transitions, fluctuations of the analyzed currents have been observed to diverge with system size. To assess whether this behavior is univers…
Nonequilibrium Fluctuation-Response Relations: From Identities to Bounds
Timur Aslyamov, Krzysztof Ptaszyński, Massimiliano Esposito
In nonequilibrium steady states of Markov jump processes, we derive exact Fluctuation-Response Relations (FRRs) that express the covariance between any pair of currents in terms of…
Dissipation enables robust extensive scaling of multipartite correlations
Krzysztof Ptaszynski, Massimiliano Esposito
We investigate the multipartite mutual information between discrete-state stochastic units interacting in a network that is invariant under unit permutations. We show that when…
Spatial Form Factor for Point Patterns: Poisson Point Process, Coulomb Gas, and Vortex Statistics
Matteo Massaro, Adolfo del Campo
Point processes have broad applications in science and engineering. In physics, their use ranges from quantum chaos to statistical mechanics of many-particle systems. We introduce…
Two transitions in complex eigenvalue statistics: Hermiticity and integrability breaking
G. Akemann, F. Balducci, A. Chenu +3
Open quantum systems have complex energy eigenvalues which are expected to follow non-Hermitian random matrix statistics when chaotic, or 2-dimensional (2d) Poisson statistics when…
Statistical prethermalization in randomly kicked many-body classical rotor system
Aritra Kundu, Tanay Nag, Atanu Rajak
We explore the phenomena of prethermalization in a many-body classical system of rotors under aperiodic drives characterised by waiting time distribution (WTD), where the waiting t…
Dissipation at limited resolutions: Power law and detection of hidden dissipative scales
Qiwei Yu, Pedro E. Harunari
Nonequilibrium systems, in particular living organisms, are maintained by irreversible transformations of energy that drive diverse functions. Quantifying their irreversibility, as…
Dynamical signatures of discontinuous phase transitions: How phase coexistence determines exponential versus power-law scaling
Krzysztof Ptaszynski, Massimiliano Esposito
There are conflicting reports in the literature regarding the finite-size scaling of the Liouvillian gap and dynamical fluctuations at discontinuous phase transitions, with various…
Kibble-Zurek Mechanism and Beyond: Lessons from a Holographic Superfluid Disk
Chuan-Yin Xia, Hua-Bi Zeng, András Grabarits +1
The superfluid phase transition dynamics and associated spontaneous vortex formation with the crossing of the critical temperature in a disk geometry is studied in the framework of…
Universal Critical Holography and Domain Wall Formation
Tian-Chi Ma, Han-Qing Shi, Hai-Qing Zhang +1
Using holography, we study the universal scaling laws governing the coarsening dynamics of strongly coupled domain walls. Specifically, we studied the universal dependence of the l…
Dissipation bounds precision of current response to kinetic perturbations
Krzysztof Ptaszynski, Timur Aslyamov, Massimiliano Esposito
The precision of currents in Markov networks is bounded by dissipation via the so-called thermodynamic uncertainty relation (TUR). In our work, we demonstrate a similar inequality…
Critical Fluctuations at Finite-Time Dynamical Phase Transition
Nalina Vadakkayil, Massimiliano Esposito, Jan Meibohm
We explore the critical properties of the recently discovered finite-time dynamical phase transition in the non-equilibrium relaxation of Ising magnets after a temperature quench.…
Minimum-dissipation principle for synchronised stochastic oscillators far from equilibrium
Jan Meibohm, Massimiliano Esposito
We prove a linear stability-dissipation relation (SDR) for -state Potts models driven far from equilibrium by a nonconservative force. At a critical coupling strength, these mod…
Small-amplitude synchronisation in driven Potts models
Jan Meibohm, Massimiliano Esposito
We study driven -state Potts models with thermodynamically consistent dynamics and global coupling. For a wide range of parameters, these models exhibit a dynamical phase transi…
Thermodynamically consistent flocking: From discontinuous to continuous transitions
Tal Agranov, Robert L. Jack, Michael E. Cates +1
We introduce a family of lattice-gas models of flocking, whose thermodynamically consistent dynamics admits a proper equilibrium limit at vanishing self-propulsion. These models ar…
Proposal for many-body quantum chaos detection
Adway Kumar Das, Cameron Cianci, Delmar G. A. Cabral +8
In this work, the term ``quantum chaos'' refers to spectral correlations similar to those found in the random matrix theory. Quantum chaos can be diagnosed through the analysis of…
