Quantum Hall Ferromagnetism in a Cavity Vacuum
Ceren B. Dag, Luis Brey, Ganpathy Murthy +1
We uncover a continuous phase transition in a quantum Hall ferromagnet (QHF) at filling factor , driven by vacuum fluctuations of a cavity. Our analysis starts with a Landau l…
Signatures of the Quantum Geometric Dipole of Interlayer Excitons in Counterflow Conductivity
Fanuel I. Mendez, Luis Brey, H. A. Fertig
Collective excitations of many-body electron systems can carry internal structure, supporting novel quantum geometric and topological properties. Among these are a quantum geometri…
Quantum Band Structure and Topology in One Dimensional Modulated Plasmonic Crystal
Luis Brey, H. A. Fertig
Band structures of electrons in a periodic potential are well-known to host topologies that impact their behaviors at edges and interfaces. The concept however is more general than…
Many-Body Quantum Geometric Dipole
H. A. Fertig, Luis Brey
Collective excitations of many-body electron systems can carry internal structure, tied to the quantum geometry of the Hilbert space in which they are embedded. This has been shown…
Spin-charge separation of plasmonic excitations in thin topological insulators
T. Stauber, G. Gómez-Santos, L. Brey
We discuss plasmonic excitations in a thin slab of a topological insulators. In the limit of no hybridization of the surface states and same electronic density of the two layers, t…
