Disorder-induced phase transitions in double HgTe quantum wells
S. S. Krishtopenko, A. V. Ikonnikov, B. Jouault +1
By using the self-consistent Born approximation, we investigate topological phase transitions in double HgTe quantum wells (QWs) induced by the short-range impurities. Following th…
Gate tunable terahertz cyclotron emission from two-dimensional Dirac fermions
B. Benhamou-Bui, C. Consejo, S. S. Krishtopenko +15
Two-dimensional Dirac fermions in HgTe quantum wells close to the topological phase transition can generate significant cyclotron emission that is magnetic field tunable in the Ter…
Magnetic-field-induced corner states in quantum spin Hall insulators
Sergey S. Krishtopenko, Frédéric Teppe
We address the problem of magnetic-field-induced corner states in quantum spin Hall insulators (QSHIs) beyond the particle-hole-symmetric limit. Starting from a realistic low-energ…
Terahertz cyclotron emission from two-dimensional Dirac fermions
S. Gebert, C. Consejo, S. S. Krishtopenko +13
Since the emergence of graphene, we have seen several proposals for the realization of Landau lasers tunable over the terahertz frequency range. The hope was that the non-equidista…
