Composite Quantum Geometry and Semiclassical Dynamics
Henry Davenport, Yoonseok Hwang, Johannes Knolle +1
We derive semiclassical equations of motion for general composite bound states in insulators and semiconductors, covering excitations such as excitons and trions. For neutral compo…
Probing topology in thin films with quantum Sondheimer oscillations
Léo Mangeolle, Johannes Knolle
Sondheimer oscillations (SO) are magnetoresistance oscillations occurring in thin films due to the commensurability between cyclotron motion and sample thickness, and are tradition…
Berry Curvature of Low-Energy Excitons in Rhombohedral Graphene
Henry Davenport, Frank Schindler, Johannes Knolle
We investigate low energy excitons in rhombohedral pentalayer graphene encapsulated by hexagonal boron nitride (hBN/R5G/hBN), focusing on the regime at the experimental twist angle…
Exciton Berryology
Henry Davenport, Johannes Knolle, Frank Schindler
In translationally invariant semiconductors that host exciton bound states, one can define an infinite number of possible exciton Berry connections. These correspond to the differe…
