Nonlinear dynamics of a dense two-dimensional dipolar exciton gas
Ronen Rapaport, Gang Chen, Steven H. Simon
We use a simple model to describe the nonlinear dynamics of a dense two dimensional dipolar exciton gas. The model predicts an initial fast expansion due to dipole-dipole pressure,…
Optical Gain from InAs Nanocrystal Quantum Dots in a Polymer Matrix
Gang Chen, Ronen Rapaport, Dan Fuchs +3
We report on the first observation of optical gain from InAs nanocrystal quantum dots emitting at 1.55 microns based on a three-beam, time resolved pump-probe technique. The nanocr…
Electrostatic traps for dipolar excitons
Ronen Rapaport, Gang Chen, Steve Simon +3
We consider the design of two-dimensional electrostatic traps for dipolar indirect excitons. We show that the excitons dipole-dipole interaction, combined with the in-plane electri…
