Magnus expansion for a chirped quantum two-level system
Peter Nalbach, Vicente Leyton
We derive a Magnus expansion for a frequency chirped quantum two-level system. We obtain a time-independent effective Hamiltonian which generates a stroboscopic time evolution. At…

Quench dynamics of neutral atoms in out-equilibrium one dimensional optical lattices
V. Leyton, A. Arguelles, M. Camargo
A quantum simulator is proposed for nucleation and growth dynamics using an out-of equilibrium optical lattice. We calculate the density of neutral atoms in the lattice and we esta…

Antiresonant quantum transport in ac driven molecular nanojunctions
Vicente Leyton, Stephan Weiss, Michael Thorwart
(Dated: July 17, 2017) We calculate the electric charge current flowing through a vibrating molecular nanojunction, which is driven by an ac voltage, in its regime of nonlinear osc…
