Large deviation full counting statistics in adiabatic open quantum dynamics

PJ Paulino, I Lesanovsky, F Carollo - Physical Review Letters, 2024 - APS
The state of an open quantum system undergoing an adiabatic process evolves by following
the instantaneous stationary state of its time-dependent generator. This observation allows …

Mathematical, thermodynamical, and experimental necessity for coarse graining empirical densities and currents in continuous space

C Dieball, A Godec - Physical Review Letters, 2022 - APS
We present general results on fluctuations and spatial correlations of the coarse-grained
empirical density and current of Markovian diffusion in equilibrium or nonequilibrium steady …

Spectral signatures of symmetry-breaking dynamical phase transitions

R Hurtado-Gutiérrez, PI Hurtado, C Pérez-Espigares - Physical Review E, 2023 - APS
Large deviation theory provides the framework to study the probability of rare fluctuations of
time-averaged observables, opening new avenues of research in nonequilibrium physics …

Finding the effective dynamics to make rare events typical in chaotic maps

R Gutiérrez, A Canella-Ortiz, C Pérez-Espigares - Physical Review Letters, 2023 - APS
Dynamical fluctuations or rare events associated with atypical trajectories in chaotic maps
due to specific initial conditions can crucially determine their fate, as the may lead to stability …

Symmetry-induced fluctuation relations in open quantum systems

S Marcantoni, C Pérez-Espigares, JP Garrahan - Physical Review E, 2021 - APS
We derive a general scheme to obtain quantum fluctuation relations for dynamical
observables in open quantum systems. For concreteness, we consider Markovian …

Moments and First-Passage Time of a Random Process for General Upper Bounds on Fluctuations of Trajectory Observables

VV Ryazanov - arxiv preprint arxiv:2401.10920, 2024 - arxiv.org
General upper bounds on fluctuations of trajectory observables were recently obtained. It
turned out that the size of fluctuations of dynamical observable is limited from below and …

Rare events, time crystals and symmetry-breaking dynamical phase transitions

R Hurtado-Gutiérrez - arxiv preprint arxiv:2404.04135, 2024 - arxiv.org
In this PhD thesis, I investigate the properties of symmetry-breaking dynamical phase
transitions that manifest in the fluctuations of time-integrated observables within classical …

Non-equilibrium Statistical Mechanics Studied Through the Lens of Stochastic Calculus

CV Dieball - 2024 - ediss.uni-goettingen.de
The microscopic world of atoms and molecules is continuously in motion, which is
manifested on the macroscopic scale as a non-zero temperature. Due to collisions with …
