Experimental study of the exciton gas-liquid transition in coupled quantum wells
We study the exciton gas-liquid transition in GaAs/AlGaAs coupled quantum wells. Below a
critical temperature, TC= 4.8 K, and above a threshold laser power density the system …

Time-resolved two-photon excitation of long-lifetime polaritons
Recent studies of two-photon excitation of exciton-polaritons in microcavities have
considered the possibility of an allowed absorption process into the 2p-state of the excitons …

Time-resolved two-photon absorption in quantum dots and polaritons
C Gautham - 2016 - d-scholarship.pitt.edu
We used two-photon absorption to study semiconductor samples. The energy of the photons
used to excite the particle is half the energy of the electronic transition. In one set of …
