Single charge-current in a normal mesoscopic region attached to superconductor leads via a coupled Poisson Non-equilibrium Green Function formalism
David Verrilli, F. P. Marin, Rafael Rangel
We study the I-V characteristic of mesoscopic systems or Quantum dot attached of a pair of superconducting leads. Interaction effects in the quantum dot are considered through the…
Multidimensional Washboard Ratchet Potentials for Frustrated Two-Dimensional Josephson-Junctions Arrays on square lattices
Rafael Rangel, Marcos Negruz
In this work, we derive an analytical procedure for obtaining a multidimensional washboard ratchet potential Uf for two-dimensional Josephson junctions array (TDJJA) with an applie…
Squeezing generation and revivals in a cavity-ion system in contact with a reservoir
R. Rangel, L. Carvalho, N. Zagury
We consider a system consisting of a single two-level ion in a harmonic trap, which is localized inside a non-ideal optical cavity at zero temperature and subjected to the action o…
Algebraic solution of master equations
R. Rangel, L. Carvalho
We present a simple analytical method to solve master equations for finite temperatures and any initial conditions, which consists in the expansion of the density operator into nor…
Persistent Non-ergodic Fluctuations in Mesoscopic Insulators
Rafael Rangel, Ernesto Medina
We give a detailed and rigorous picture of the mesoscopic conductance fluctuations in the deep insulating regime (DIR) within the Nguyen, Spivak and Shklovskii model including spin…
