متن کاملBerry Curvature in Graphene: a New Approach
In the present paper we have directly computed the Berry curvature terms relevant for Graphene in the presence of an inhomogeneous lattice distortion. We have employed the generalized Foldy Wouthuysen framework, developed by some of us [4, 5]. Our general expressions for Berry curvature, for the special case of homogeneous distortion, reduce to the previously obtained results [13]. We propose s...
