Collective dynamics of interacting Ising spins: Exact results for the Bethe lattice
Low temperature dynamic molecules magnet crystal electron spin ground state electronic since the gyration mechanics coupling nuclear

Abstract: Anomalous transport in one dimensional translation invariant Hamiltonian systems with short range interactions, is shown to belong in general to the KPZ universality class. Exact asymptotic ...
Exact results for the criticality of quench dynamics in quantum Ising models
Exact results criticality of quench dynamics quantum Ising models
2010/4/12
Based on the obtained exact results we systematically study the quench dynamics of a one-dimensional spin-1/2 transverse field Ising model with zero- and finite-temperature initial states. We focus on...
