Correlations and diagonal entropy after quantum quenches in XXZ chains

Lorenzo Piroli, Eric Vernier, Pasquale Calabrese +1

We study quantum quenches in the XXZ spin- Heisenberg chain from families of ferromagnetic and antiferromagnetic initial states. Using Bethe ansatz techniques, we compute shor…

From the Quantum Transfer Matrix to the Quench Action: The Loschmidt echo in Heisenberg spin chains

Lorenzo Piroli, Balázs Pozsgay, Eric Vernier

We consider the computation of the Loschmidt echo after quantum quenches in the interacting Heisenberg spin chain both for real and imaginary times. We study two-site product…
