Higgs amplitude mode in ballistic superconducting hybrid junctions
Pierre Vallet, Jérôme Cayssol
In superconductors (SC), the Higgs amplitude mode is a coherent oscillation of the order parameter typically generated by THz laser irradiation. In this paper we propose to probe t…
Mesoscopic Klein-Schwinger effect in graphene
A. Schmitt, P. Vallet, D. Mele +12
Strong electric field annihilation by particle-antiparticle pair creation, also known as the Schwinger effect, is a non-perturbative prediction of quantum electrodynamics. Its expe…
Three-dimensional chiral Veselago lensing
Serguei Tchoumakov, Jérôme Cayssol, Adolfo G. Grushin
The effect by which light focuses upon entering a medium with a negative refractive index, known as Veselago lensing, may enable optical imaging below the diffraction limit. Simila…
Conservation of chirality at a junction between two Weyl semimetals
Serguei Tchoumakov, Bogusz Bujnowski, Jonathan Noky +3
In Weyl semimetals the location of linear band crossings, the Weyl cones, is not bound to any high symmetry point of the Brillouin zone, unlike the Dirac nodes in graphene. This fl…
Topological and geometrical aspects of band theory
J. Cayssol, J. -N. Fuchs
This paper provides a pedagogical introduction to recent developments in geometrical and topological band theory following the discovery of graphene and topological insulators. Amu…
Photocurrent and photoconductance of an helical edge state
Jonathan Atteia, Jérôme Cayssol
We consider the helical edge state of a Quantum Spin Hall insulator, connected between two leads, and irradiated by a monochromatic and circularly polarized electromagnetic wave. T…
