The photoluminescence of excitons confined in an electric field tunable coupled AlAs/GaAs
quantum well has been investigated at T≥ 350 mK and magnetic fields H≤ 14 T. In the …

In a high magnetic field, such that the distance between the Landau levels exceeds the
exciton Rydberg, the triplet interaction term becomes the lowest state of the system. Under …

In a high magnetic field, such that the distance between the Landau levels exceeds the
binding energy of an exciton, an exciton gas in a semiconductor is capable of forming the …

We have studied anomalies in the temperature dependence of transient photoconductivity in
host oxide insulators or semiconductors La-Cu-O, Y-Cu-O, Ba-Bi-O, Bi-(La, Y)-Cu-O etc. with …

We propose a transient grating experiment in order to observe exciton Bose condensation.
We show that for typical parameters in semiconductors the velocities of first and second …

Multiphoton STE generation in α-SiO 2 was investigated in the high intensity regime (from
0.1 to a few TW cm− 2) using 250 fs UV pulses, for photon energies of 4.4 and 4 eV …

In a recent letter, Fortin et al.[l] have reported an unusual propagation regime for the
excitonic current in Cu, O. Those authors [l] observed a marked reduction in the velocity …
