Quantum Phase Transitions detected by a local probe using Time Correlations and Violations of Leggett-Garg Inequalities
F. J. Gómez-Ruiz, J. J. Mendoza-Arenas, F. J. Rodríguez +2
In the present paper we introduce a way of identifying quantum phase transitions of many-body systems by means of local time correlations and Leggett-Garg inequalities. This proced…
Bichromatic dressing of a quantum dot detected by a remote second quantum dot
M. Maragkou, C. Sánchez-Muñoz, S. Lazić +8
We demonstrate an information transfer mechanism between two dissimilar remote InAs/GaAs quantum dots weakly coupled to a common photonic crystal microcavity. Bichromatic excitatio…
Generation of two identical photons from a quantum dot in a microcavity
E. del Valle, A. Gonzalez-Tudela, E. Cancellieri +2
We propose and characterize a two-photon emitter in a highly polarised, monochromatic and directional beam, realized by means of a quantum dot embedded in a linearly polarized cavi…
Pauli blockade of the electron spin flip in bulk GaAs
A. Amo, L. Vina, P. Lugli +3
By means of time-resolved optical orientation under strong optical pumping, the k-dependence of the electron spin-flip time (t_sf) in undoped GaAs is experimentally determined. t_s…
Fermionic Atoms in Optical Superlattices
B. Paredes, C. Tejedor, J. I. Cirac
Fermionic atoms in an optical superlattice can realize a very peculiar Anderson lattice model in which impurities interact with each other through a discretized set of delocalized…
Fermi-edge singularities in linear and non-linear ultrafast spectroscopy
D. Porras, J. Fernandez-Rossier, C. Tejedor
We discuss Fermi-edge singularity effects on the linear and nonlinear transient response of an electron gas in a doped semiconductor. We use a bosonization scheme to describe the l…
