interfaces and of other systems that exhibit two-dimensional or quasi-two-dimensional …

Condensation and pattern formation in cold exciton gases in coupled quantum wells

LV Butov - Journal of Physics: Condensed Matter, 2004 - iopscience.iop.org
Bound electron–hole pairs—excitons—are light Bose particles with a mass comparable to or
smaller than that of the free electron. Since the quantum degeneracy temperature scales …

Excitations from a filled Landau level in the two-dimensional electron gas

C Kallin, BI Halperin - Physical Review B, 1984 - APS
We consider an interacting two-dimensional electron system, with a uniform positive
background, in a strong perpendicular magnetic field at zero temperature, under conditions …

Excitons in topological Kondo insulators: Theory of thermodynamic and transport anomalies in

J Knolle, NR Cooper - Physical review letters, 2017 - APS
Kondo insulating materials lie outside the usual dichotomy of weakly versus correlated—
band versus Mott—insulators. They are metallic at high temperatures but resemble band …

Anomalous transport and luminescence of indirect excitons in AlAs/GaAs coupled quantum wells as evidence for exciton condensation

LV Butov, AI Filin - Physical Review B, 1998 - APS
Due to the long lifetime of indirect (interwell) excitons, exciton condensation (analogous to
the Bose-Einstein condensation of bosons) is expected to occur in coupled quantum wells …

A dipole interpretation of the v= 12 state

V Pasquier, FDM Haldane - Nuclear Physics B, 1998 - Elsevier
We consider the problem of bosonic particles interacting repulsively in a strong magnetic

quasi-two-dimensional excitons. We calculate the internal structures and dispersion …

Exciton condensation in coupled quantum wells

LV Butov - Solid State Communications, 2003 - Elsevier
