WITS Node Seminar: Dr. Roland Cristopher F. Caballar (NITheP/UKZN)
The National Institute for Theoretical Physics, and the Centre for Theoretical Physics, School of Physics, would like to invite to its coming talk in the theoretical physics seminar series, entitled:
"OneDimensional Homogeneous Open Quantum Walks"
to be presented by Dr. Roland Cristopher F. Caballar (NITheP/UKZN)
Abstract: In this talk, we consider a system undergoing an open quantum walk on a onedimensional lattice. Each jump of the system between adjacent lattice points in a given direction corresponds to a jump operator, with these jump operators either commuting or not commuting. We examine the dynamics of the system undergoing this open quantum walk, in particular deriving analytically the probability distribution of the system, as well as examining numerically the behavior of the probability distribution over long time steps. The resulting distribution is shown to have multiple components, which fall under two general categories, namely normal and solitonic components. The analytic computation of the probability distribution for the system undergoing this open quantum walk allows us to determine at any instant of time the dynamical properties of the system.
