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…
