Entanglement dynamics of thermofield double states in integrable models
Gianluca Lagnese, Pasquale Calabrese, Lorenzo Piroli
We study the entanglement dynamics of thermofield double (TFD) states in integrable spin chains and quantum field theories. We show that, for a natural choice of the Hamiltonian ei…
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…
Local correlations in the attractive 1D Bose gas: from Bethe ansatz to the Gross-Pitaevskii equation
Lorenzo Piroli, Pasquale Calabrese
We consider the ground-state properties of an extended one-dimensional Bose gas with pointwise attractive interactions. We take the limit where the interaction strength goes to zer…
