Revealing topological Dirac fermions at the surface of strained HgTe thin films via Quantum Hall transport spectroscopy
C. Thomas, O. Crauste, B. Haas +7
We demonstrate evidences of electronic transport via topological Dirac surface states in a thin film of strained HgTe. At high perpendicular magnetic fields, we show that the elect…
Topological surface states of strained Mercury-Telluride probed by ARPES
Olivier Crauste, Yoshiyuki Ohtsubo, Philippe Ballet +6
The topological surface states of strained HgTe have been measured using high-resolution ARPES measurements. The dispersion of surface states form a Dirac cone, which origin is clo…
Strained HgTe: a textbook 3D topological insulator
Clément Bouvier, Tristan Meunier, Philippe Ballet +3
Topological insulators can be seen as band-insulators with a conducting surface. The surface carriers are Dirac particles with an energy which increases linearly with momentum. Thi…
Topological quantization by controlled paths: application to Cooper pairs pumps
Raphaël Leone, Laurent Lévy
When physical systems are tunable by three classical parameters, level degeneracies may occur at isolated points in parameter space. A topological singularity in the phase of the d…
How free are Composite Fermions at ? A NMR investigation
N. Freytag, M. Horvatić, C. Berthier +2
NMR measurements of the electron spin polarization have been performed on a 2D electron system at and around half-filled lowest Landau level. Comparing the magnetic field and the t…
