Quantum Critical Scaling of Dirty Bosons in Two Dimensions
R. Ng, E. S. Sorensen
We determine the dynamical critical exponent, , appearing at the Bose glass to superfluid transition in two dimensions by performing large scale numerical studies of two microsc…
Exact Real Time Dynamics of Quantum Spin Systems Using the Positive-P Representation
Ray Ng, Erik Sorensen
We discuss a scheme for simulating the real time quantum quench dynamics of interacting quantum spin systems within the positive-P formalism. As model systems we study the transver…
Simulation of the Dynamics of Many-Body Quantum Spin Systems Using Phase-Space Techniques
Ray Ng, Piotr Deuar, Erik Sorensen
We reformulate the full quantum dynamics of spin systems using a phase space representation based on SU(2) coherent states which generates an exact mapping of the dynamics of any s…
Non-Markovian Quantum State Diffusion: Application to Quantum Jumps in Mg
Joshua Wilkie, Ray Ng
Non-Markovian quantum state diffusion (NMQSD) is an exact method for calculating the reduced density matrix of an arbitrary subsystem interacting linearly with the radiation field.…
Numerical Implementation of Non-Markovian Quantum State Diffusion
Joshua Wilkie, Ray Ng
Non-Markovian quantum state diffusion (NMQSD) is a non-relativistic but otherwise exact theory which expresses the reduced density matrix of an arbitrary subsystem, interacting lin…
