Simplifying the simulation of local Hamiltonian dynamics
Ayaka Usui, Anna Sanpera, María García Díaz
Local Hamiltonians, , describe non-trivial -body interactions in quantum many-body systems. Here, we address the dynamical simulatability of a -local Hamiltonian by a si…

Microscopic contributions to the entropy production at all times: From nonequilibrium steady states to global thermalization
Ayaka Usui, Krzysztof Ptaszyński, Massimiliano Esposito +1
Based on exact integration of the Schrödinger equation, we numerically study microscopic contributions to the entropy production for the single electron transistor, a paradigmatic…
