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…
