Interpreting Stone's model of Berry Phases
Paolo Carra
We show that a simple quantum-mechanical model, put forward by Stone sometime ago, affords description of site magnetoelectricity, a phenomenon which takes place in crystals (and m…
X-ray Dichroism in Noncetrosymmetric crystals
Paolo Carra, Andres Jerez, Ivan Marri
In this paper the authors analyse near-edge absorption of x rays in noncentrosymmetric crystals. The work is motivated by recent observations of x-ray dichroic effects which stems…
X-ray dichroism and orbital anapoles
Paolo Carra, Andres Jerez, Ivan Marri
We present a theoretical analysis of photo-absorption spectroscopies in noncentrosymmetric systems, covering both x-ray and optical regions. Integrated dichroic spectra are interpr…
Band structure and atomic sum rules for x-ray dichroism
R. Benoist, P. Carra, O. K. Andersen
Corrections to the atomic orbital sum rule for circular magnetic x-ray dichroism in solids are derived using orthonormal LMTOs as a single-particle basis for electron band states.
X-ray natural circular dichroism
Paolo Carra, Robert Benoist
This paper discusses a theory of natural circular dichroism in the x-ray region. Integrated spectra are interpreted in terms of microscopic effective operators, which are derived i…
