Higgs-mediated optical amplification in a non-equilibrium superconductor
Michele Buzzi, Gregor Jotzu, Andrea Cavalleri +7
The quest for new functionalities in quantum materials has recently been extended to non-equilibrium states, which are interesting both because they exhibit new physical phenomena…
Topological Floquet Engineering of Twisted Bilayer Graphene
Gabriel E. Topp, Gregor Jotzu, James W. McIver +3
We investigate the topological properties of Floquet-engineered twisted bilayer graphene above the magic angle driven by circularly polarized laser pulses. Employing a full Moiré-u…
Microscopic theory for the light-induced anomalous Hall effect in graphene
S. A. Sato, J. W. McIver, M. Nuske +9
We employ a quantum Liouville equation with relaxation to model the recently observed anomalous Hall effect in graphene irradiated by an ultrafast pulse of circularly polarized lig…
