Strain-tuning of quantum dot optical transitions via laser-induced surface defects
Strain-tuning quantum dot optical transitions laser-induced surface defects
2011/8/17
Abstract: We discuss the fine-tuning of the optical properties of self-assembled quantum dots by the strain perturbation introduced by laser-induced surface defects. We show experimentally that the qu...
On-demand control of photon echoes far exceeding the spin coherence constraint via coherence swapping between optical and spin transitions
On-demand control photon echoes spin coherence constraint optical spin transitions

Using on-demand coherence conversion via optical locking in conventional stimulated (three-pulse) photon echoes, ultralong, ultraefficient photon storage has been observed in a rare-earth Pr3+ doped Y...
Photonic Josephson effect, phase transitions, and chaos in optomechanical systems

Manifestations of quantum aspects on a macroscopic scale are supposed to bring new light on
our understanding of fundamental physics. In this paper we consider such issues among others by
analyzing ...
Nonlinear thermotropic and thermo-optical behaviour of planar oriented textures in nematic liquid crystals at phase transitions
