Gyrotropy from Extrinsic Geometry in Twisted Materials
Spenser Talkington, Eugene J Mele
Gyrotropy in twisted bilayer graphene can be used as a signature of interlayer electronic coupling. Gyrotropy can emerge in the absence of interlayer coupling in time-reversal symm…
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 for…
Terahertz Landau level spectroscopy of Dirac fermions in millimeter-scale twisted bilayer graphene
Benjamin F. Mead, Spenser Talkington, An-Hsi Chen +8
Exotic electronic physics including correlated insulating states and fractional Chern insulators have been observed in twisted bilayer graphene in a magnetic field when the Fermi v…
Many-Body Photon Blockade and Quantum Light Generation from Cavity Quantum Materials
Benjamin Kass, Spenser Talkington, Ajit Srivastava +1
The strong coupling regime of photons and quantum materials inside optical cavities has emerged as a promising environment for manipulating states of matter with light. Here, in tu…
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…
Floquet-Bloch Theory for Nonperturbative Response to a Static Drive
Christophe De Beule, Steven Gassner, Spenser Talkington +1
We develop the Floquet-Bloch theory of noninteracting fermions on a periodic lattice in the presence of a constant electric field. As long as the field lies along a reciprocal latt…
Terahertz Circular Dichroism in Commensurate Twisted Bilayer Graphene
Spenser Talkington, Eugene J. Mele
We report calculations of terahertz ellipticities in large-angle, 21.79 and 38.21, commensurate twisted bilayer graphene, and predict values as high as 1.5 millideg…
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…
Dissipation Induced Flat Bands
Spenser Talkington, Martin Claassen
Flat bands are an ideal environment to realize unconventional electronic phases. Here, we show that fermionic systems with dissipation governed by a Bloch Lindbladian can realize d…
Fractional Chern insulators with a non-Landau level continuum limit
David Bauer, Spenser Talkington, Fenner Harper +2
Recent developments in fractional quantum Hall (FQH) physics highlight the importance of studying FQH phases of particles partially occupying energy bands that are not Landau level…
Efficient unitary method for simulation of driven quantum dot systems
Spenser Talkington, HongWen Jiang
Density matrices evolved according the von Neumann equation are commonly used to simulate the dynamics of driven quantum systems. However, computational methods using density matri…
