Quantized frequency-domain polarization of driven phases of matter
Ian Mondragon-Shem, Ivar Martin, A. Alexandradinata +1
Periodically driven quantum systems can realize novel phases of matter that do not exist in static settings. We study signatures of these drive-induced phases on the -dimens…
Topological Frequency Conversion in a Driven Dissipative Quantum Cavity
Frederik Nathan, Ivar Martin, Gil Refael
Recent work (PRX 7, 041008) has shown that a spin coupled to two externally supplied circularly-polarized electromagnetic modes can effectuate a topological, quantized transfer of…
Floquet dynamics of classical and quantum cavity fields
Ivar Martin
We show that the time-dependence of electromagnetic field in a parametrically modulated cavity can be effectively analyzed using a . The map relates the field states…
Topological classification of quasi-periodically driven quantum systems
Philip J. D. Crowley, Ivar Martin, Anushya Chandran
Few level quantum systems driven by incommensurate fundamental frequencies exhibit temporal analogues of non-interacting phenomena in spatial dimensio…
Topological insulators in twisted transition metal dichalcogenide homobilayers
Fengcheng Wu, Timothy Lovorn, Emanuel Tutuc +2
We show that moiré bands of twisted homobilayers can be topologically nontrivial, and illustrate the tendency by studying valence band states in valleys of twisted bilayer…
Theory of phonon-mediated superconductivity in twisted bilayer graphene
Fengcheng Wu, A. H. MacDonald, Ivar Martin
We present a theory of phonon-mediated superconductivity in near magic angle twisted bilayer graphene. Using a microscopic model for phonon coupling to moiré band electrons, we fin…
