Signatures of the Quantum Geometric Dipole of Interlayer Excitons in Counterflow Conductivity
This research investigates how interlayer excitons possess a Quantum Geometric Dipole (QGD), an internal structure tied to momentum in their energy bands. The study uses counterflow conductivity as a tunable probe to measure this QGD, showing that its components are sensitive to the periodic potential and driving fields, offering insights into the quantum geometry of many-body excitations.
