Quantized Transport of Gap Solitons in the Harper-Hofstadter Model
Oliver Ashfield, Henry Davenport, Tom Sheppard +6
We investigate the dynamics of gap solitons found in the Harper-Hofstadter model with an additional cubic nonlinearity, such as that describing weakly-interacting cold atoms or a K…
Exciton Alchemy: Chern Excitons from Trivial Bands
Yoonseok Hwang, Henry Davenport, Frank Schindler
Exciton topology is commonly inherited from the topology of the underlying electronic bands. Recent theoretical work, however, has shown that the exciton Chern number can in genera…
Anomalous suppression of quantum chaos between two integrable limits
Roopayan Ghosh, Henry Davenport, Frank Schindler
Level statistics in non-integrable quantum many-body systems with time reversal symmetry are expected to follow the Gaussian Orthogonal Ensemble (GOE), a hallmark of quantum chaos.…
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…
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…
Interaction-induced crystalline topology of excitons
Henry Davenport, Johannes Knolle, Frank Schindler
We apply the topological theory of symmetry indicators to interaction-induced exciton band structures in centrosymmetric semiconductors. Crucially, we distinguish between the topol…
