Magnetic Field Induced Redistribution of Exciton-Polariton Density on Confined Modes

Benoît Marie Joseph Deveaud, François Morier-Genoud, Gaël Nardin, Barbara Pietka

The influence of magnetic field on confined exciton-polariton modes inside a semiconductor microcavity is discussed. The three-dimensional confinement for exciton-polaritons is achieved by the mesa structures confining the photonic part of polaritons. We o ...

Collisional damping of dipole oscillations in a trapped polariton gas

Benoît Marie Joseph Deveaud, François Morier-Genoud, Marcia Portella Oberli, Barbara Pietka, Taofiq Paraïso, Roland Cerna

We study the relaxation dynamics of a trapped polariton gas in the nonlinear regime. We excite the three lowest energy states of the system and observe the time evolution of the polariton density in the momentum space. At a low excitation power, the dynami ...

Analytical method for determining quantum well exciton properties in a magnetic field

Benoît Marie Joseph Deveaud, François Morier-Genoud, Barbara Pietka

We develop an analytical approximate method for determining the Bohr radii of Wannier-Mott excitons in thin quantum wells under the influence of magnetic field perpendicular to the quantum well plane. Our hybrid variational-perturbative method allows us to ...
