Cascade of Phase Transitions and Dirac Revivals in Magic Angle Graphene
Uri Zondiner, Asaf Rozen, Daniel Rodan-Legrain +10
Twisted bilayer graphene near the magic angle exhibits remarkably rich electron correlation physics, displaying insulating, magnetic, and superconducting phases. Here, using measur…
Hierarchy of many-body invariants and quantized magnetization in anomalous Floquet insulators
Frederik Nathan, Dmitry A. Abanin, Netanel H. Lindner +2
We uncover a new family of few-body topological phases in periodically driven fermionic systems in two dimensions. These phases, which we term correlation-induced anomalous Floquet…
Topological superconductivity in planar Josephson junctions: Narrowing down to the nanowire limit
F. Setiawan, Ady Stern, Erez Berg
We theoretically study topological planar Josephson junctions (JJs) formed from spin-orbit-coupled two-dimensional electron gases (2DEGs) proximitized by two superconductors and su…
Topology and localization of a periodically driven Kitaev model
I. C. Fulga, M. Maksymenko, M. T. Rieder +2
Periodically driven quantum many-body systems support anomalous topological phases of matter, which cannot be realized by static systems. In many cases, these anomalous phases can…
