DOI: 10.1088/1742-5468/ab6093
Abstract: Following on from our recent work, we investigate a stochastic approach to non-equilibrium quantum spin systems. We show how the method can be applied to a variety of physical observables and for different initial conditions.… read more here.

DOI: 10.1103/physreve.106.014128
Abstract: The Fredkin spin chain serves as an interesting theoretical example of a quantum Hamiltonian whose ground state exhibits a phase transition between three distinct phases, one of which violates the area law. Here we consider… read more here.
