Chiral Phonons with Giant Magnetic Moments in a Topological Crystalline Insulator
Felix G. G. Hernandez, Andrey Baydin, Swati Chaudhary +10
We have studied the magnetic response of transverse optical phonons in PbSnTe films. Polarization-dependent terahertz magnetospectroscopy measurements revealed Zeeman…
Engineering topological phases in triple HgTe/CdTe quantum wells
G. J. Ferreira, D. R. Candido, F. G. G. Hernandez +4
Quantum wells formed by layers of HgTe between HgCdTe barriers lead to two-dimensional (2D) topological insulators, as predicted by the BHZ model. Here, we theoreticall…
Magnetic Control of Soft Chiral Phonons in PbTe
Andrey Baydin, Felix G. G. Hernandez, Martin Rodriguez-Vega +10
PbTe crystals have a soft transverse optical phonon mode in the terahertz frequency range, which is known to efficiently decay into heat-carrying acoustic phonons, resulting in ano…
Multiple crossing of Landau levels of two-dimensional fermions in double HgTe quantum wells
G. M. Gusev, E. B. Olshanetsky, F. G. G. Hernandez +3
The double quantum well systems consisting of two HgTe layers separated by a tunnel-transparent barrier are expected to manifest a variety of phase states including two-dimensional…
Electrical control of spin relaxation anisotropy during drift transport in a two-dimensional electron gas
F. G. G. Hernandez, G. J. Ferreira, M. Luengo-Kovac +4
Spin relaxation was studied in a two-dimensional electron gas confined in a wide GaAs quantum well. Recently, the control of the spin relaxation anisotropy by diffusive motion was…
Two-dimensional topological insulator state in double HgTe quantum well
G. M. Gusev, E. B. Olshanetsky, F. G. G. Hernandez +3
The two-dimensional topological insulator phase has been observed previously in single HgTe-based quantum wells with inverted subband ordering. In double quantum wells (DQWs), coup…
