Effects of discrete topology on quantum transport across a graphene junction: A quantum gravity analogue
Naveed Ahmad Shah, Alonso Contreras-Astorga, François Fillion-Gourdeau +3
In this article, we investigate the effect of next-to-the-nearest atom hopping on Klein tunnelling in graphene. An effective quantum dynamics equation is obtained based on an emerg…
Two-dimensional Dirac matter in the semiclassical regime
F. Fillion-Gourdeau, E. Lorin, S. Maclean
The semiclassical regime of 2D static Dirac matter is obtained from the Dirac equation in curved space-time. To simplify the formulation, the Cartesian space-time geometry parametr…
Plunging in the Dirac sea using graphene quantum dots
F. Fillion-Gourdeau, P. Levesque, S. MacLean
The dynamics of low energy charge carriers in a graphene quantum dot subjected to a time-dependent local field is investigated numerically. In particular, we study a configuration…
Pulse shaping in the terahertz frequency range for the control of photo-excited carriers in graphene
Denis Gagnon, Joey Dumont, François Fillion-Gourdeau +1
The shape of a few-cycle terahertz (THz) laser pulse can be optimized to provide control over conduction band populations in graphene. To demonstrate this control in a theoretical…
Carrier-envelope phase effects in graphene
C. Lefebvre, D. Gagnon, F. Fillion-Gourdeau +1
We numerically study the interaction of a terahertz pulse with monolayer graphene. We observe that the electron momentum density is affected by the carrier-envelope phase (CEP) of…
Coherent destruction of tunneling in graphene irradiated by elliptically polarized lasers
Denis Gagnon, François Fillion-Gourdeau, Joey Dumont +2
Photo-induced transition probabilities in graphene are studied theoretically from the viewpoint of Floquet theory. Conduction band populations are computed for a strongly, periodic…
