Large inverted band-gap in strained three-layer InAs/GaInSb quantum wells
C. Avogadri, S. Gebert, S. S. Krishtopenko +17
Quantum spin Hall insulators (QSHIs) based on HgTe and three-layer InAs/GaSb quantum wells (QWs) have comparable bulk band-gaps of about 10--18~meV. The former however features a b…
Experimental evidence for long-distance electrodynamic intermolecular forces
Mathias Lechelon, Yoann Meriguet, Matteo Gori +12
Both classical and quantum electrodynamics predict the existence of dipole-dipole long-range electrodynamic intermolecular forces; however, these have never been hitherto experimen…
Plasmon recombination in narrowgap HgTe quantum wells
V Ya Aleshkin, G Alymov, A A Dubinov +2
The dispersion laws of two-dimensional plasmons in narrow-gap HgTe/CdHgTe quantum wells are calculated taking into account the spatial dispersion of the electron susceptibility. At…
Many-particle effects in optical transitions from zero-mode Landau levels in HgTe quantum wells
S. S. Krishtopenko, A. M. Kadykov, S. Gebert +9
We report on the far-infrared magnetospectroscopy of HgTe quantum wells with inverted band ordering at different electron concentrations. We particularly focus on optical transitio…
Hybridization of topological surface states with a flat band
Sergey S. Krishtopenko, Mauro Antezza, Frédéric Teppe
We address the problem of hybridization between topological surface states and a non-topological flat bulk band. Our model, being a mixture of three-dimensional Bernevig-Hughes-Zha…
Unconventional Reentrant Quantum Hall Effect in a HgTe/CdHgTe Double Quantum Well
M. V. Yakunin, S. S. Krishtopenko, S. M. Podgornykh +7
We report on observation of an unconventional structure of the quantum Hall effect (QHE) in a -type HgTe/CdHgTe double quantum well (DQW) consisting of two HgTe lay…
