Theory of zero-field superconducting diode effect in twisted trilayer graphene
Harley D. Scammell, J. I. A. Li, Mathias S. Scheurer
In a recent experiment [Lin et al., arXiv:2112.07841], the superconducting phase hosted by a heterostructure of mirror-symmetric twisted trilayer graphene and WSe was shown to…
Zero-field superconducting diode effect in small-twist-angle trilayer graphene
Jiang-Xiazi Lin, Phum Siriviboon, Harley D. Scammell +7
The critical current of a superconductor can be different for opposite directions of current flow when both time-reversal and inversion symmetry are broken. %When time-reversal and…
A new flavor of correlation and superconductivity in small twist-angle trilayer graphene
Phum Siriviboon, Jiang-Xiazi Lin, Xiaoxue Liu +8
When layers of graphene are rotationally misaligned by the magic angle, the moiré superlattice features extremely flat bands. Due to the enhanced density of states, the Coulomb int…
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…
Intrinsic first and higher-order topological superconductivity in a doped topological insulator
Harley D. Scammell, Julian Ingham, Max Geier +1
We explore higher order topological superconductivity in an artificial Dirac material with intrinsic spin-orbit coupling, which is a doped topological insulator in t…
Correlated physics in an artificial triangular anti-dot lattice
Z. E. Krix, H. D. Scammell, O. P. Sushkov
This work considers a two-dimensional artificial triangular anti-dot lattice (TAL); a semiconductor based artificial crystal hosting Dirac cones, flat bands and Fermi surface nesti…
Higher-order topological superconductivity from repulsive interactions in kagome and honeycomb systems
Tommy Li, Max Geier, Julian Ingham +1
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…
