Stochastic trajectories and excursions in a double quantum dot system

Guilherme Fiusa, Pedro E. Harunari, Alberto J. B. Rosal +2

We investigate the trajectory-level dynamics of a double quantum dot system using the newly developed formalism of stochastic excursions. This approach extends full counting statis…

Mutual Multilinearity of Nonequilibrium Network Currents

Sara Dal Cengio, Pedro E. Harunari, Vivien Lecomte +1

Continuous-time Markov chains have been successful in modelling systems across numerous fields, with currents being fundamental entities that describe the flows of energy, particle…

Framework for fluctuating times and counting observables in stochastic excursions

Guilherme Fiusa, Pedro E. Harunari, Abhaya S. Hegde +1

Many natural systems exhibit dynamics characterized by alternating phases or recurring sets of states. Describing the fluctuations of such systems over stochastic trajectories is n…

Counting observables in stochastic excursions

Guilherme Fiusa, Pedro E. Harunari, Abhaya S. Hegde +1

Understanding fluctuations of observables across stochastic trajectories is essential for various fields of research, from quantum thermal machines to biological motors. We introdu…

Inference of entropy production for periodically driven systems

Pedro E. Harunari, Carlos E. Fiore, Andre C. Barato

The problem of estimating entropy production from incomplete information in stochastic thermodynamics is essential for theory and experiments. Whereas a considerable amount of work…
