Moiré -valley bilayers: quasi-one-dimensional physics, unconventional spin textures and twisted van Hove singularities
Julian Ingham, Mathias S. Scheurer, Harley D. Scammell
Motivated by the discovery of quasi-two-dimensional kagome metals AVSb, we consider the theory of twisted bilayers in which the Fermi surface is near the -point. Surpris…
Topological superconductivity from repulsive interactions in twisted WSe
Daniele Guerci, Daniel Kaplan, Julian Ingham +2
The recent observation of superconductivity in twisted bilayer WSe raises intriguing questions concerning the origin and the properties of superconducting states realized in ba…
Quadratic Dirac fermions and the competition of ordered states in twisted bilayer graphene
Julian Ingham, Tommy Li, Mathias S. Scheurer +1
Magic-angle twisted bilayer graphene (TBG) exhibits a captivating phase diagram as a function of doping, featuring superconductivity and a variety of insulating and magnetic states…
Chiral excitonic order from twofold van Hove singularities in kagome metals
Harley D. Scammell, Julian Ingham, Tommy Li +1
Recent experiments on kagome metals AVSb (A=K,Rb,Cs) [M. Kang et al., Nat. Phys. 18, 301-308 (2022)] identify twofold van Hove singularities (TvHS) with opposite concavity…
Nested Fermi surfaces and correlated electronic phases in hole-doped semiconductor quantum wells
Tommy Li, Julian Ingham, Harley D. Scammell
We demonstrate the existence of novel interaction effects in hole-doped semiconductor quantum wells which are connected to dramatic changes in the Fermi surface geometry occurring…

We discuss a pairing mechanism in interacting two-dimensional multipartite lattices that intrinsically leads to a second order topological superconducting state with a spatially mo…
Artificial Graphene: Unconventional Superconductivity in a Honeycomb Superlattice
Tommy Li, Julian Ingham, Harley D. Scammell
Artificial lattices have served as a platform to study the physics of unconventional superconductivity. We study semiconductor artificial graphene -- a honeycomb superlattice impos…
Enhanced creation of high energy particles in colliding laser beams
Michael Kuchiev, Julian Ingham
The creation of particles by two colliding strong laser beams is considered. It is found that the electron-positron pairs created in the laser field via the Schwinger mechanism may…
High energy photon production in strong colliding laser beams
Michael Kuchiev, Julian Ingham
The collision of two intense, low-frequency laser beams is considered. The pairs created in this field are shown to exhibit recollisions, which take place at high energy a…
