Single spin resonance driven by electric modulation of the g factor anisotropy
Alejandro Ferrón, Santiago A. Rodríguez, Sergio S. Gómez +2
We address the problem of electronic and nuclear spin resonance of an individual atom on a surface driven by a scanning tunnelling microscope. Several mechanisms have been proposed…
Fast optical control of a coded qubit in a triple quantum dot
Diego S. Acosta Coden, Sergio S. Gomez, Rodolfo H. Romero +2
In this work, we study strategies for the optical control, within the dipole approximation, of a qubit encoded in the three-electron states of a triple quantum dot. The system is d…
Optimal control of a charge qubit in a double quantum dot with a Coulomb impurity
Diego S. Acosta Coden, Rodolfo H. Romero, Alejandro Ferrón +1
We study the efficiency of modulated laser pulses to produce efficient and fast charge localization transitions in a two-electron double quantum dot. We use a configuration interac…
Electronic properties of transition metal atoms on CuN/Cu(100)
Alejandro Ferrón, Jose Luis Lado, Joaquín Fernández-Rossier
We study the nature of spin excitations of individual transition metal atoms (Ti, V, Cr, Mn, Fe, Co and Ni) deposited on a CuN/Cu(100) surface using both spin-polarized density…
Impurity Effects in Two-Electron Coupled Quantum Dots: Entanglement Modulation
Diego S. Acosta Coden, Rodolfo H. Romero, Alejandro Ferrón +1
We present a detailed analysis of the electronic and optical properties of two-electron quantum dots with a two-dimensional Gaussian confinement potential. We study the effects of…
Near-threshold properties of the electronic density of layered quantum-dots
Alejandro Ferrón, Pablo Serra, Omar Osenda
We present a way to manipulate an electron trapped in a layered quantum dot based on near-threshold properties of one-body potentials. We show that potentials with a simple global…
