Kondo excitons in self-assembled quantum dots
A. O. Govorov, K. Karrai, R. J. Warburton
We describe novel excitons in quantum dots by allowing for an interaction with a Fermi sea of electrons. We argue that these excitons can be realized very simply with self-assemble…
Enrichment of CH3F nuclear spin isomers by resonant microwave radiation
O. I. Permyakova, E. Ilisca, P. L. Chapovsky
Theoretical model of the coherent control of nuclear spin isomers by microwave radiation has been developed. Model accounts the M-degeneracy of molecular states and molecular cente…
Polarized excitons in nanorings and the `optical' Aharonov-Bohm effect
A. O. Govorov, S. E. Ulloa, K. Karrai +1
The quantum nature of matter lies in the wave function phases that accumulate while particles move along their trajectories. A prominent example is the Aharonov-Bohm phase, which h…
Delocalization of Wannier-Stark ladders by phonons: tunneling and stretched polarons
Wei Zhang, Alexander O. Govorov, Sergio E. Ulloa
We study the coherent dynamics of a Holstein polaron in strong electric fields. A detailed analytical and numerical analysis shows that even for small hopping constant and weak ele…
Friedel oscillations of the magnetic field penetration in systems with spatial quantization
M. V. Entin, L. I. Magarill, M. M. Mahmoodian
The magnetic field, applied to a size-quantized system produces equilibrium persistent current non-uniformly distributed across the system. The distributions of dia- and paramagnet…
Magneto-optical properties of charged excitons in quantum dots
A. O. Govorov, C. Schulhauser, D. Haft +7
We present both experimental and theoretical results on the influence of a magnetic field on excitons in semiconductor quantum dots. We find a pronounced difference between the str…
