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…
Pulse shape optimization for electron-positron production in rotating fields
François Fillion-Gourdeau, Florian Hebenstreit, Denis Gagnon +1
We optimize the pulse shape and polarization of time-dependent electric fields to maximize the production of electron-positron pairs via strong field quantum electrodynamics proces…
Suppression of multiphoton resonances in driven quantum systems via pulse shape optimization
Denis Gagnon, François Fillion-Gourdeau, Joey Dumont +2
This Letter demonstrates control over multiphoton absorption processes in driven two-level systems, which include for example superconducting qubits or laser-irradiated graphene, t…
