Ballistic magnetotransport in graphene
Ke Wang, T. A. Sedrakyan
We report that a perpendicular magnetic field introduces an anomalous interaction correction, , to the static conductivity of doped graphene in the ballistic regime. The correc…
Interaction effects in graphene in a weak magnetic field
Ke Wang, M. E. Raikh, T. A. Sedrakyan
A weak perpendicular magnetic field, , breaks the chiral symmetry of each valley in the electron spectrum of graphene, preserving the overall chiral symmetry in the Brillouin zo…
Theory for the negative longitudinal magnetoresistance in the quantum limit of Kramers Weyl semimetals
Bo Wan, Frank Schindler, Ke Wang +4
Negative magnetoresistance is rare in non-magnetic materials. Recently, a negative magnetoresistance has been observed in the quantum limit of -AgSe, where only one band of…
Persistent Friedel oscillations in Graphene due to a weak magnetic field
Ke Wang, M. E. Raikh, T. A. Sedrakyan
Two opposite chiralities of Dirac electrons in a 2D graphene sheet modify the Friedel oscillations strongly: electrostatic potential around an impurity in graphene decays much fast…
