Bose–Einstein condensation of excitons in bilayer electron systems

JP Eisenstein, AH MacDonald - Nature, 2004 - nature.com
An exciton is the particle-like entity that forms when an electron is bound to a positively
charged 'hole'. An ordered electronic state in which excitons condense into a single …

Evidence for a topological excitonic insulator in InAs/GaSb bilayers

L Du, X Li, W Lou, G Sullivan, K Chang, J Kono… - Nature …, 2017 - nature.com
Electron–hole pairing can occur in a dilute semimetal, transforming the system into an
excitonic insulator state in which a gap spontaneously appears at the Fermi surface …

Coupled electron-hole transport

U Sivan, PM Solomon, H Shtrikman - Physical review letters, 1992 - APS
We report on transport measurements in a novel system composed of two parallel 2D
electron and hole gases separated by a barrier which is high enough to prevent tunneling …

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 …

Double quantum well electron-hole systems in strong magnetic fields

D Yoshioka, AH MacDonald - Journal of the Physical Society of …, 1990 - jstage.jst.go.jp
抄録 Two-dimensional electron-hole systems with long excitonic life-times can be realized in
double quantum well systems by applying an electric field which localizes electrons and …

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 …

Quasi-two-dimensional excitons in finite magnetic fields

YE Lozovik, IV Ovchinnikov, SY Volkov, LV Butov… - Physical Review B, 2002 - APS

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

Exciton condensation in coupled quantum wells

LV Butov - Solid State Communications, 2003 - Elsevier
Bound electron–hole pairs—excitons—are Bose particles with small mass. Exciton Bose–
Einstein condensation is expected to occur at a few degrees Kelvin—a temperature many …

Electron-hole superconductivity

DV Fil, SI Shevchenko - Low Temperature Physics, 2018 - pubs.aip.org
