Stable Wave-Function Zeros Indicate Exciton Topology
Yoonseok Hwang, Henry Davenport, Frank Schindler
Excitons are bound states of electrons and holes whose band topology arises from an interplay between the topology of the underlying electronic bands and the structure of the elect…
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…
Momentum-space modulated symmetries in the Luttinger liquid
Alexandre Chaduteau, Nyan Raess, Henry Davenport +1
The chiral Luttinger liquid develops quantum chaos as soon as a -- however slight -- nonlinear dispersion is introduced for the microscopic electronic degrees of freedom. For this…
