Trajectory-Resolved Weiss Fields for Quantum Spin Dynamics
S. E. Begg, A. G. Green, M. J. Bhaseen
We explore the dynamics of quantum spin systems in two and three dimensions using an exact mapping to classical stochastic processes. In recent work we explored the effectiveness o…

Time-Evolving Weiss Fields in the Stochastic Approach to Quantum Spins
S. E. Begg, A. G. Green, M. J. Bhaseen
We investigate non-equilibrium quantum spin systems via an exact mapping to stochastic differential equations. This description is invariant under a shift in the mean of the Gaussi…

Fluctuations and Non-Hermiticity in the Stochastic Approach to Quantum Spins
S. E. Begg, A. G. Green, M. J. Bhaseen
We investigate the non-equilibrium dynamics of isolated quantum spin systems via an exact mapping to classical stochastic differential equations. We show that one can address signi…
