The dynamics of quantum criticality via Quantum Monte Carlo and holography
William Witczak-Krempa, Erik Sorensen, Subir Sachdev
Understanding the real time dynamics of quantum systems without quasiparticles constitutes an important yet challenging problem. We study the superfluid-insulator quantum-critical…

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…
