Prethermalization in a nonintegrable quantum spin chain after a quench.
We study the dynamics of a quantum Ising chain after the sudden introduction of a nonintegrable long-range interaction. Via an exact mapping onto a fully connected lattice of hard-core bosons, we show that a prethermal state emerges and we investigate its features by focusing on a class of physically relevant observables. In order to gain insight into the eventual thermalization, we outline a d...
متن کاملSpin diffusion from an inhomogeneous quench in an integrable system
Generalized hydrodynamics predicts universal ballistic transport in integrable lattice systems when prepared in generic inhomogeneous initial states. However, the ballistic contribution to transport can vanish in systems with additional discrete symmetries. Here we perform large scale numerical simulations of spin dynamics in the anisotropic Heisenberg XXZ spin 1/2 chain starting from an inhomo...
متن کاملQuantum-classical phase transition of the escape rate in a biaxial spin system with an arbitrarily directed magnetic field
(February 1, 2008) We investigate the escape rate of a biaxial spin particle with an arbitrarily directed magnetic field in the easy plane, described by Hamiltonian H = −AS2 z − BS2 x − HxSx − HzSz, (A > B > 0). We derive an effective particle potential by using the method of particle mapping. With the help of the criterion for the presence of a first-order quantum-classical transition of the e...
متن کاملQuasiparticle explanation of the weak-thermalization regime under quench in a nonintegrable quantum spin chain
The eigenstate thermalization hypothesis provides one picture of thermalization in a quantum system by looking at individual eigenstates. However, it is also important to consider how local observables reach equilibrium values dynamically. Quench protocol is one of the settings to study such questions. A recent numerical study [Bañuls, Cirac, and Hastings, Phys. Rev. Lett. 106, 050405 (2007)] o...
متن کاملQuasiparticle explanation of “weak thermalization” regime under quench in a non-integrable quantum spin chain
Eigenstate Thermalization Hypothesis provides one picture of thermalization in a quantum system by looking at individual eigenstates. However, it is also important to consider how local observables reach equilibrium values dynamically. Quench protocol is one of the settings to study such questions. A recent numerical study [Bañuls, Cirac, and Hastings, Phys. Rev. Lett. 106, 050405 (2011)] of a ...
