Competing Orders Driven by Wigner Crystal Phase in Rhombohedral Graphene

Zekang Zhou, Kilian Krötzsch, Raphaël Ayache +7

Rhombohedral graphene systems provide a unique platform where strong electronic interactions and nontrivial band topology coexist at low carrier densities and high displacement fie…

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…

Tunable interplay of orbital and spin magnetization in trigonal tellurium

Zhenqi Hua, Chang Niu, Sandeep Joy +8

Orbital effects, despite their fundamental significance and potential to engender novel physical phenomena and enable new applications, have long been underexplored compared to the…

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…

Wigner crystallization in Bernal bilayer graphene

Sandeep Joy, Brian Skinner

In Bernal bilayer graphene (BBG), a perpendicular displacement field flattens the bottom of the conduction band and thereby facilitates the formation of strongly correlated electro…

Cascade of multi-electron bubble phases in monolayer graphene at high Landau level filling

Fangyuan Yang, Ruiheng Bai, Alexander A. Zibrov +6

The phase diagram of an interacting two-dimensional electron system in a high magnetic field is enriched by the varying form of the effective Coulomb interaction, which depends str…

Upper bound on the window of density occupied by microemulsion phases in two-dimensional electron systems

Sandeep Joy, Brian Skinner

In two-dimensional electronic systems, direct first-order phase transitions are prohibited as a consequence of the long-range Coulomb interaction, which implies a stiff energetic p…

Wigner crystallization at large fine structure constant

Sandeep Joy, Brian Skinner

We consider the fate of the Wigner crystal state in a two dimensional system of massive Dirac electrons as the effective fine structure constant is increased. In a Dirac system…

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…
