Direct observation of Floquet-Bloch states in monolayer graphene
Dongsung Choi, Masataka Mogi, Umberto De Giovannini +6
Floquet engineering is a novel method of manipulating quantum phases of matter via periodic driving [1, 2]. It has successfully been utilized in different platforms ranging from ph…
Attosecond magnetization dynamics in non-magnetic materials driven by intense femtosecond lasers
Ofer Neufeld, Nicolas Tancogne-Dejean, Umberto De Giovannini +2
Irradiating solids with ultrashort laser pulses is known to initiate femtosecond timescale magnetization dynamics. However, sub-femtosecond spin dynamics have not yet been observed…
Floquet engineering the band structure of materials with optimal control theory
Alberto Castro, Umberto de Giovannini, Shusuke A. Sato +2
We demonstrate that the electronic structure of a material can be deformed into Floquet pseudo-bands with arbitrarily tailored shapes. We achieve this goal with a novel combination…
Floquet Engineering of Magnetism in Topological Insulator Thin Films
Xiaoyu Liu, Peizhe Tang, Hannes Hübener +3
Dynamic manipulation of magnetism in topological materials is demonstrated here via a Floquet engineering approach using circularly polarized light. Increasing the strength of the…
Floquet states in dissipative open quantum systems
S. A. Sato, U. De Giovannini, S. Aeschlimann +3
We theoretically investigate basic properties of nonequilibrium steady states of periodically-driven open quantum systems based on the full solution of the Maxwell-Bloch equation.…
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…
