Detection of spin injection into a double quantum dot: Violation of magnetic-field-inversion symmetry of nuclear polarization instabilities
Detection of spin injection double quantum dot: Violation nuclear polarization instabilities
2010/11/19
In mesoscopic systems with spin-orbit coupling, spin-injection into quantum dots at zero magnetic eld is expected under a wide range of conditions. However, up to now, a viable approach for experimen...
Ruelle-Lanford functions for quantum spin systems
Ruelle-Lanford functions quantum spin systems
2010/10/27
We prove a large deviation principle for the expectation of macroscopic observables in quantum (and classical) Gibbs states. Our proof is based on Ruelle-Lanford functions [20, 34] and direct subaddit...
Linearly independent pure-state decomposition and quantum state discrimination
Linearly independent decomposition quantum discrimination
2010/11/8
We put the pure-state decomposition mathematical property of a mixed state to a physical test. We begin by characterizing all the possible decompositions of a rank-two mixed state by means of the comp...
Kicked-rotor quantum resonances in position space: Application to systems of experimental interest
quantum resonances position space experimental interest
2010/10/21
In a previous article [1], we have presented an original approach of the quantum resonances of the kicked rotor. We have described the quantum resonances in position space, for strongly localized wave...
Effects of In-Plane Magnetic Fields on the Electronic Cyclotron Effective Mass and Landé Factor in GaAs-(Ga,Al)As Quantum Wells
Magnetic fields Quantum wells g-factor Cyclotron effective mass
2010/9/25
The dependence of the electron Land´e g-factor on carrier confinement in quantum wells recently gained both experimental and theoretical interest. The g factor of electrons in GaAs-(Ga,Al)As qua...
