Is disorder a friend or a foe to melting of Wigner-Mott insulators?
Mohammed Hammam, Cyprian Lewandowski, Vladimir Dobrosavljevic +1
Wigner crystals are extremely fragile, which is shown to result from very strong geometric frustration germane to long-range Coulomb interactions. Physically, this is manifested by…
Chiral Wigner crystal phases induced by Berry curvature
Sandeep Joy, Leonid Levitov, Brian Skinner
We consider the impact of Berry phase on the Wigner crystal (WC) state of a two-dimensional electron system. We consider first a model of Bernal bilayer graphene with a perpendicul…
Disorder-induced liquid-solid phase coexistence in 2D electron systems
Sandeep Joy, Brian Skinner
Recent imaging experiments show a surprisingly robust regime of liquid-solid phase coexistence in a 2D electron system near the quantum melting/freezing transition, with the two ph…
Transparent mirror effect in twist-angle-disordered bilayer graphene
Sandeep Joy, Saad Khalid, Brian Skinner
When light is incident on a medium with spatially disordered index of refraction, interference effects lead to near-perfect reflection when the number of dielectric interfaces is l…
