Interplay between transport and quantum coherences in free fermionic systems
Tony Jin, Tristan Gautié, Alexandre Krajenbrink +2
We study the quench dynamics in free fermionic systems in the prototypical bipartitioning protocol obtained by joining two semi-infinite subsystems prepared in different states, ai…
Generic transport formula for a system driven by Markovian reservoirs
Tony Jin, Michele Filippone, Thierry Giamarchi
We present a generic, compact formula for the current flowing in interacting and non-interacting systems which are driven out-of-equilibrium by biased reservoirs described by Lindb…
Equilibration of quantum cat states
Tony Jin
We study the equilibration properties of isolated ergodic quantum systems initially prepared in a cat state, i.e a macroscopic quantum superposition of states. Our main result cons…
From stochastic spin chains to quantum Kardar-Parisi-Zhang dynamics
Tony Jin, Alexandre Krajenbrink, Denis Bernard
We introduce the asymmetric extension of the Quantum Symmetric Simple Exclusion Process which is a stochastic model of fermions on a lattice hopping with random amplitudes. In this…
Universal fluctuations around typicality for quantum ergodic systems
Michel Bauer, Denis Bernard, Tony Jin
For a quantum system in a macroscopically large volume , prepared in a pure state and subject to maximally noisy or ergodic unitary dynamics, the reduced density matrix of any s…
Open Quantum Symmetric Simple Exclusion Process
Denis Bernard, Tony Jin
We introduce and solve a model of fermions hopping between neighbouring sites on a line with random Brownian amplitudes and open boundary conditions driving the system out of equil…
