Decoherence in the quantum Ising model with transverse dissipative interaction in the strong-coupling regime
Decoherence in the quantum Ising model with transverse dissipative interaction in the strong-coupling regime
We study the decoherence dynamics of a quantum Ising lattice of finite size with a transverse dissipative interaction, namely, the coupling with the bath is assumed perpendicular to the direction of the spins interaction and parallel to the external magnetic field. In the limit of small transverse field, the eigenstates …
