Magnetic quantum correlation in the 1D transverse-field XXZ model
Salimeh Mahdavifar, Saeed Mahdavifar, R. Jafari
One-dimensional spin-1/2 systems are well-known candidates to study the quantum correlations between particles. In the condensed matter physics, studies often are restricted to the…

Decoherence from spin environments: Loschmidt echo and quasiparticle excitations
R. Jafari, Henrik Johannesson
We revisit the problem of decoherence of a qubit centrally coupled to an interacting spin environment, here modeled by a quantum compass chain or an extended XY model in a staggere…

Loschmidt Echo Revivals: Critical and Noncritical
R. Jafari, Henrik Johannesson
A quantum phase transition is generally thought to imprint distinctive characteristics on the nonequilibrium dynamics of a closed quantum system. Specifically, the Loschmidt echo a…
