Dynamics of Loschmidt echoes from operator growth in noisy quantum many-body systems
Takato Yoshimura, Lucas Sá
We study the dynamics of Loschmidt echoes in noisy quantum many-body systems without conservation laws. We first show that the operator Loschmidt echo in noisy unitary dynamics is…

Hydrodynamic fluctuations of stochastic charged cellular automata
Takato Yoshimura, Žiga Krajnik
We study charge fluctuations of a family of stochastic charged cellular automata away from the deterministic single-file limit and obtain the exact typical charge probability distr…

Theory of Irreversibility in Quantum Many-Body Systems
Takato Yoshimura, Lucas Sá
We address the longstanding challenge in quantum many-body theory of reconciling unitary dynamics with irreversible relaxation. In classical chaos, the unitary evolution operator d…
