Simulating ground states and elementary excitations with PEPS (Dr. Laurens Vanderstraeten)

Simulating ground states and elementary excitations with PEPS
In this talk we review variational PEPS algorithms for two-dimensional quantum spin systems. First we focus on the optimization of ground-state approximations for generic hamiltonians, and show some benchmark results. Next, we build excited-state wavefunctions on top of such a PEPS ground state using a generalization of the single-mode approximation. [mehr]

Large deviations and cMPS in open quantum dynamics

Large deviations and cMPS in open quantum dynamics
In this talk I will describe a perspective on the dynamics of Markovian open quantum systems based on the study of the statistical properties of ensembles of quantum trajectories. This "thermodynamics of quantum trajectories" approach is to dynamics what the standard equilibrium configuration ensemble method is for statics. [mehr]
