A brief note about V$_2$O$_3$

TL;DR

This paper clarifies recent experimental results on V₂O₃, discusses their theoretical interpretation, comments on x-ray dichroism experiments, and offers personal insights on the role of non-local correlations in its insulating ground state.

Contribution

It provides clarification of experimental interpretations and discusses the significance of non-local correlations in V₂O₃'s insulating phase.

Findings

Clarification of x-ray scattering experimental results

Comment on K edge linear dichroism experiments

Opinion on non-local correlations in V₂O₃

Abstract

This note summarizes some recently published results, that are reported in cond-mat today. Its aim is twofold. First, I believe that it is worthwhile to clarify the theoretical interpretation of a series of x-ray scattering experimental results, whose implications are apparently not well-known in the recent literature. A comment about K edge linear dichroism experiments is also provided. In second place, I would like to add a personal opinion about the role of non-local correlations in the insulating ground-state of V$_2$O$_3$.
