Quasi-soliton scattering in quantum spin chains
Rogier Vlijm, Martin Ganahl, Davide Fioretto +4
The quantum scattering of magnon bound states in the anisotropic Heisenberg spin chain is shown to display features similar to the scattering of solitons in classical exactly solva…
Quench action approach for releasing the Néel state into the spin-1/2 XXZ chain
Michael Brockmann, Bram Wouters, Davide Fioretto +3
The steady state after a quantum quench from the Néel state to the anisotropic Heisenberg model for spin chains is investigated. Two methods that aim to describe the postquench non…
Quenching the Anisotropic Heisenberg Chain: Exact Solution and Generalized Gibbs Ensemble Predictions
Bram Wouters, Jacopo De Nardis, Michael Brockmann +3
We study quenches in integrable spin-1/2 chains in which we evolve the ground state of the antiferromagnetic Ising model with the anisotropic Heisenberg Hamiltonian. For this nontr…
Exact out-of-equilibrium central spin dynamics from integrability
Davide Fioretto, Jean-Sébastien Caux, Vladimir Gritsev
We consider a Gaudin magnet (central spin model) with a time-dependent exchange couplings. We explicitly show that the Schrödinger equation is analytically solvable in terms of gen…
