Basis-Independent Spectral Methods for Non-linear Optical Response in Arbitrary Tight-binding Models
S. M. João, J. M. V. P. Lopes
In this paper, we developed a basis-independent perturbative method for calculating the non-linear optical response of arbitrary non-interacting tight-binding models. Our method is…
Nonlinear optical responses of crystalline systems: Results from a velocity gauge analysis
D. J. Passos, G. B. Ventura, J. M. Viana Parente Lopes +2
In this work, the difficulties inherent to perturbative calculations in the velocity gauge are addressed. In particular, it is shown how calculations of nonlinear optical responses…
Gauge covariances and nonlinear optical responses
G. B. Ventura, D. J. Passos, J. M. B. Lopes dos Santos +2
The formalism of the reduced density matrix is pursued in both length and velocity gauges of the perturbation to the crystal Hamiltonian. The covariant derivative is introduced as…
Rabi oscillations of matter wave solitons in optical lattices
Yu. V. Bludov, V. V. Konotop, M. Salerno
Inter-band Rabi oscillations of gap soliton matter waves induced by time dependent periodic forces in combined linear and nonlinear optical lattices are for the first time demonstr…
