Conditional phase shift from a quantum dot in a pillar microcavity
quantum dot pillar microcavity Quantum Physics
2010/11/8
Large conditional phase shifts from coupled atom-cavity systems are a key requirement for building a spin photon interface. This in turn would allow the realisation of hybrid quantum information schem...
We calculate the mesoscopic admittance G(!) of a double quantum dot, which can be measured
directly using microwave techniques. This quantity shows a rich behavior. In particular, it is directly sens...
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...
Correlation energy in a triplet state of a two-electron spherical quantum dot
Spherical quantum dot Square well confinement Correlation energies Singlet and Triplet states
2010/7/8
Correlation energies in the (1s-1p) triplet state of a two-electron spherical QD with square-well potential confinement are estimated for dots of different radii. The results are presented taking GaAs...
