Glass Patterns in Twisted Disordered Crystals
Aaron Dunbrack
Twisting and stacking two copies of a 2D crystal can produce a long-wavelength periodic interference pattern known as a moiré pattern. Performing the same procedure with an aperiod…

Optimizing superlattice bilayer graphene for a fractional Chern insulator
Dathan Ault-McCoy, M. Nabil Y. Lhachemi, Aaron Dunbrack +2
Bernal-stacked bilayer graphene modulated by a superlattice potential is a highly tunable system predicted to realize isolated topological flat bands. In this work we calculate the…

Quantum Geometric Helical Superconductivity
Aaron Dunbrack, Pauli Virtanen, Tero T. Heikkilä
Several physical phenomena in superconductors, such as helical superconductivity and the diode effect, rely on breaking time-reversal symmetry. This symmetry-breaking is usually ac…
