Electronic transitions in disc-shaped quantum dots induced by twisted light
G. F. Quinteiro, P. I. Tamborenea
We theoretically investigate the absorption and emission of light carrying orbital angular momentum (twisted-light) by quasi-two-dimensional (disc-shaped) quantum dots in the prese…
Hartree-Fock ground state of the two-dimensional electron gas with Rashba spin-orbit interaction
L. O. Juri, P. I. Tamborenea
We search for the uniform Hartree-Fock ground state of the two-dimensional electron gas formed in semiconductor heterostructures including the Rashba spin-orbit interaction. We ide…
Relaxation mechanism for electron spin in the impurity band of n-doped semiconductors
Pablo I. Tamborenea, Dietmar Weinmann, Rodolfo A. Jalabert
We propose a mechanism to describe spin relaxation in n-doped III-V semiconductors close to the Mott metal-insulator transition. Taking into account the spin-orbit interaction indu…
Level structure and spin-orbit effects in semiconductor nanorod dots
C. L. Romano, S. E. Ulloa, P. I. Tamborenea
We investigate theoretically how the spin-orbit Dresselhaus and Rashba effects influence the electronic structure of quasi-one-dimensional semiconductor quantum dots, similar to th…
A Hopf bifurcation with a strong incommensurate frequency response in quantum wells
Adriano A. Batista, Bjorn Birnir, Pablo I. Tamborenea
The behavior of delta-doped wide quantum well heterostructures in the presence of intense far-infrared radiation is studied using semiconductor Bloch equations. A quantum well is d…
