Intrinsic nonlinear Hall effect beyond Bloch geometry

Raffaele Resta

The theory of the intrinsic Hall effect, both linear and nonlinear, is rooted in a geometry which is defined in the Bloch-vector parameter space; the formal expressions are mostly…

Nonadiabatic quantum geometry and optical conductivity

Raffaele Resta

The ground-state quantum geometry is at the root of several static and adiabatic properties, while genuinely dynamic properties are routinely addressed via Kubo formulae, whose ess…

Drude weight in presence of nonlocal potentials

Raffaele Resta

The nonlocal potential contributes an extra term to the velocity operator; I show here that such term affects the formal expression of the Drude weight in a nontrivial way. Notably…

The Insulating State of Matter: A Geometrical Theory

Raffaele Resta

In 1964 W. Kohn published the milestone paper "Theory of the insulating state'", according to which insulators and metals differ in their ground state. Even before the system is ex…

Orbital magnetization and Chern number in a supercell framework: Single k-point formula

D. Ceresoli, R. Resta

The key formula for computing the orbital magnetization of a crystalline system has been recently found [D. Ceresoli, T. Thonhauser, D. Vanderbilt, R. Resta, Phys. Rev. B {\bf 74},…

Electron Localization at Metal Surfaces

L. De Santis, R. Resta

We investigate some surfaces of a paradigmatic sp bonded metal--namely, Al(110), Al(100), and Al(111)--by means of the "electron localization function" (ELF), implemented in a firs…
