Popis:	We analyse the problem of the electronic correlations in V2O3, focusing on its low-temperature antiferromagnetic phase, in the light of recent experimental findings. In fact, the implications of the vanadium K-edge linear dichroism data demand further theoretical investigations to explain the consequences of the non-reciprocal gyrotropic effect, which has not been considered by previous theoretical models. The analysis of all the available experimental data indicates 2/m as a magnetic space group for the ground state, instead of C2h⊗. Such a reduction of the symmetry can be given by the onset of an orbital ordering in the system. We illustrate the merits and drawbacks of the proposed solution.
