Self-organized Floquet band geometry in cavity-driven quantum materials
Christopher Yang, Gil Refael, Mark S. Rudner +1
Floquet engineering has emerged as a powerful route to dynamically control band structure and topology in quantum materials, but most implementations rely on externally imposed las…
Light-induced trion-exciton competition revealed by ultrafast photoemission
Ittai Sidilkover, Nir Hen Levin, Yuval Nitzav +11
Strong Coulomb interactions in low-dimensional quantum materials give rise to emergent bound states such as excitons and trions. Trions are conventionally secondary excitations, re…
Quantum geometry and bounds on dissipation in slowly driven quantum systems
Iliya Esin, Ãtienne Lantagne-Hurtubise, Frederik Nathan +1
We show that energy dissipation in slowly-driven, Markovian quantum systems at low temperature is linked to the geometry of the driving protocol through the quantum (or Fubini-Stud…
Topological frequency conversion in rhombohedral multilayer graphene
Ãtienne Lantagne-Hurtubise, Iliya Esin, Gil Refael +1
We show that rhombohedral multilayer graphene supports topological frequency conversion, whereby a fraction of electrons transfer energy between two monochromatic light sources at…
Evidence of Floquet electronic steady states in graphene under continuous-wave mid-infrared irradiation
Yijing Liu, Christopher Yang, Gabriel Gaertner +9
Light-induced phenomena in materials can exhibit exotic behavior that extends beyond equilibrium properties, offering new avenues for understanding and controlling electronic phase…
