Short-time vs. long-time dynamics of entanglement in quantum lattice models
R. G. Unanyan, D. Muth, M. Fleischhauer
We study the short-time evolution of the bipartite entanglement in quantum lattice systems with local interactions in terms of the purity of the reduced density matrix. A lower bou…
Effective magnetic fields for stationary light
J. Otterbach, J. Ruseckas, R. G. Unanyan +2
We describe a method to create effective gauge potentials for stationary-light polaritons in two or three spatial dimensions. When stationary light is created in the interaction wi…
Confinement limit of Dirac particles in scalar 1D potentials
R. G. Unanyan, J. Otterbach, M. Fleischhauer
We present a general proof that Dirac particles cannot be localized below their Compton length by symmetric but otherwise arbitrary scalar potentials. This proof does not invoke th…
