Hole Spin Mixing in InAs Quantum Dot Molecules (2009)
Doty, M. F., Climente, J. I., Greilich, A., Bracker, A. S., Gammon, D.
Holes confined in single InAs quantum dots have recently emerged as a promising system for the storage or manipulation of quantum information. These holes are often assumed to have only heavy-hole...
Nanoscopic semiconductor quantum rings (2008)
J. I. Climente, Josep Planelles
Els anells quàntics semiconductors són una classe particular de punts quàntics de forma toroïdal. De la mateixa manera que en punts quàntics, el nombre de portadors de càrrega confinats en...

Nanoscopic semiconductor quantum rings (2008)
J.I. Climente, J.I. Climente, Josep Planelles, J.L. Domingo, J.L. Domingo
Semiconductor quantum rings are a particular type of toroidal shaped quantum dot-like structures. As in quantum dots, the number of carriers confined within these structures can be controlled one by...
Antibonding ground states in semiconductor artificial molecules (2008)
Doty, M. F., Climente, J. I., Korkusinski, M., Scheibner, M., Bracker, A. S., Hawrylak, P., ...
The spin-orbit interaction is a crucial element of many semiconductor spintronic technologies. Here we report the first experimental observation, by magneto-optical spectroscopy, of a remarkable...
Planelles, J., Rajadell, F., Climente, J. I.
A comprehensive study of anisotropic quantum rings, QRs, subject to axial and in- plane magnetic field, both aligned and transverse to the anisotropy direction, is carried out. Elliptical QRs for a...
Electron states in quantum rings with defects under axial or in-plane magnetic fields (2007)
Planelles, J., Rajadell, F., Climente, J. I.
A comprehensive study of anisotropic quantum rings, QRs, subject to axial and in-plane magnetic field, both aligned and transverse to the anisotropy direction, is carried out. Elliptical QRs for a...
Electronic states of laterally coupled quantum rings (2006)
Planelles, J., Rajadell, F., Climente, J. I., Royo, M., Movilla, J. L.
The conduction band electron states of laterally-coupled semiconductor quantum rings are studied within the frame of the effective mass envelope function theory. We consider the effect of axial and...
Phonon-induced electron relaxation in weakly-confined single and coupled quantum dots (2006)
Climente, J. I., Bertoni, A., Goldoni, G., Molinari, E.
We investigate charge relaxation rates due to acoustic phonons in weakly-confined quantum dot systems, including both deformation potential and piezoelectric field interactions. Single-electron...
Electronic structure of few-electron concentric double quantum rings (2006)
Climente, J. I., Planelles, J., Barranco, M., Malet, F., Pi, M.
The ground state structure of few-electron concentric double quantum rings is investigated within the local spin density approximation. Signatures of inter-ring coupling in the addition energy...
Magnetic field dependence of hole levels in self-assembled InAs quantum dots (2005)
Climente, J. I., Planelles, J., Pi, M., Malet, F.
Recent magneto-transport experiments of holes in InGaAs quantum dots [D. Reuter, P. Kailuweit, A.D. Wieck, U. Zeitler, O. Wibbelhoff, C. Meier, A. Lorke, and J.C. Maan, Phys. Rev. Lett. 94, 026808...
Aharonov-Bohm effect for pedestrian (2005)
Planelles, J., Climente, J. I., Movilla, J. L.
When a magnetic field pierces a multiple-connected quantum system, the corresponding wavefunction is altered although no net Lorentz force acts upon its carriers. This is the so called Aharonov-Bohm...
