Two examples of discrete-time quantum walks taking continuous steps
Alex D. Gottlieb
This note introduces some examples of quantum random walks in d-dimensional Eucilidean space and proves the weak convergence of their rescaled n-step densities. One of the examples…

Accuracy of the time-dependent Hartree-Fock approximation
Claude Bardos, Francois Golse, Alex D. Gottlieb +1
This article examines the time-dependent Hartree-Fock (TDHF) approximation of single-particle dynamics in systems of interacting fermions. We find the TDHF approximation to be accu…
