Microscopic quantum phenomena such as interference or phase coherence between different quantum states are rarely manifest in macroscopic systems due to a lack of significant correlation between different states. An exciton system is one candidate for observation of possible quantum collective effects. In the dilute limit, excitons in semiconductors behave as bosons and are expected to undergo Bose-Einstein condensation (BEC) at a temperature several orders of magnitude higher than for atomic… Expand
Magnetic micro-confinement of quantum degenerate gases
IN this dissertation we explore the basic principles of the magnetic micro-confinement of the quantum degenerate gases where the approach of the so-called two-dimensional magnetic lattices has beenExpand


Long-range transport in excitonic dark states in coupled quantum wells
Photoluminescence measurements of InGaAs quantum wells are reported and the observation of an effect by which luminescence from excitons appears hundreds of micrometres away from the laser excitation spot is reported. Expand
Macroscopically ordered state in an exciton system
Photoluminescence measurements of a quasi-two-dimensional exciton gas in GaAs/AlGaAs coupled quantum wells and the observation of a macroscopically ordered exciton state are reported. Expand
Tunnelling and relaxation in semiconductor double quantum wells
Double quantum wells are among the simplest semiconductor heterostructures exhibiting tunnel coupling. The existence of a quantum confinement effect for the energy levels of a narrow single quantumExpand
Excitonic effects in coupled quantum wells.
A variational model of the coupled excitons is constructed that explains these effects in terms of Coulomb mixing of the delocalized electron states and deduces the actual bare-electron level splittings rather than the exciton splITTings. Expand
Towards Bose–Einstein condensation of excitons in potential traps
Inspired by experiments on atom condensation, and using specially designed semiconductor nanostructures, the photoluminescence measurements show that the quasi-two-dimensional excitons indeed condense at the bottom of the traps, giving rise to a statistically degenerate Bose gas. Expand

The spontaneous interlayer phase coherent (111) state of a bilayer quantum Hall system at filling factor nu = 1 may be viewed as a condensate of interlayer particle-hole pairs or excitons. We showExpand
Ultrafast terahertz probes of transient conducting and insulating phases in an electron–hole gas
An ultrafast terahertz probe is employed to investigate directly the dynamical interplay of optically-generated excitons and unbound electron–hole pairs in GaAs quantum wells, revealing an unexpected quasi-instantaneous excitonic enhancement, the formation of insulating excitONS on a 100-ps timescale, and the conditions under which excitonics populations prevail.

Superfluidity of indirect excitons and biexcitons in coupled quantum wells and superlattices
The collective properties of indirect excitons in coupled quantum wells (CQWs) are considered. The energy of the ground state of the exciton liquid as a function of the density of electrons e andExpand

Stimulated scattering of indirect excitons in coupled quantum wells: signature of a degenerate Bose-gas of excitons.
A strong enhancement of the exciton scattering rate to the low-energy states with increasing concentration of the indirect excitons is observed and bosonic stimulation ofexciton scattering is revealed, which is a signature of a degenerate Bose-gas of exciteons. Expand
