Time-resolved two-photon excitation of long-lifetime polaritons
Chitra Gautham, Mark Steger, David Snoke +2
Recent studies of two-photon excitation of exciton-polaritons in microcavities have considered the possibility of an allowed absorption process into the -state of the excitons…
Slow reflection and two-photon generation of microcavity exciton-polaritons
Mark Steger, Chitra Gautham, David W. Snoke +2
We resonantly inject polaritons into a microcavity and track them in time and space as they feel a force due to the cavity gradient. This is an example of "slow reflection," as the…
Long Range Ballistic Motion and Coherent Flow of Long Lifetime Polaritons
Mark Steger, Gangqiang Liu, Bryan Nelsen +5
Exciton-polaritons can be created in semiconductor microcavities. These quasiparticles act as weakly interacting bosons with very light mass, of the order of times the va…
Research News -- Progess in determination of neutrino oscillation parameters
B. Ananthanarayan, Chitra Gautham, Aquila Mavalankar +3
Recent results from the MINOS experiment at Fermilab reconfirm neutrino oscillations. We describe briefly this experiment and discuss how this and other experiments enable us to de…
