Gyrotropy from Extrinsic Geometry in Twisted Materials
Spenser Talkington, Eugene J Mele
The paper shows that gyrotropic optical activity in twisted bilayer materials can arise from the physical arrangement of the layers (extrinsic geometry) independent of electronic s…
Polarization-Resolved Photon Statistics of Cavity Quantum Materials
Benjamin Kass, Spenser Talkington, Martin Claassen
By forming hybrid light-matter states, optical cavities offer a route for engineering material properties, however, unambiguously probing the effects of light-matter coupling remai…
Ultrastrong Coupling Signatures in Photon Statistics from Terahertz Higgs-Polaritons
Spenser Talkington, Benjamin Kass, Martin Claassen
The ultrastrong coupling regime of cavity photons and quantum materials has emerged as a pathway to modify materials properties, however definitive signatures of ultrastrong coupli…
Weak localization and universal conductance fluctuations in large area twisted bilayer graphene
Spenser Talkington, Debarghya Mallick, An-Hsi Chen +7
We study diffusive magnetotransport in highly p-doped large area twisted bilayer graphene in 1°, 7°, 9° and 20° samples. We report weak localization in twisted bilayer graphene…
Electric Field Tunable Band Gap in Commensurate Twisted Bilayer Graphene
Spenser Talkington, Eugene J. Mele
Bernal bilayer graphene exhibits a band gap that is tunable through the infrared with an electric field. We show that sublattice odd commensurate twisted bilayer graphene (C-TBG) e…
Linear and Non-Linear Response of Quadratic Lindbladians
Spenser Talkington, Martin Claassen
Quadratic Lindbladians encompass a rich class of dissipative electronic and bosonic quantum systems, which have been predicted to host new and exotic physics. In this study, we dev…
