"Quasiparticle evolution and pseudogap formation in V2O3: An infrared spectroscopy study";
Physical Review B, 77 (2008), 113107-1 - 113107-4.



English abstract:
The infrared conductivity of V2O3 is measured in the whole phase diagram. Quasiparticles appear above the
Néel temperature TN and eventually disappear further enhancing the temperature, leading to a pseudogap in the
optical spectrum above 425 K. Our calculations demonstrate that this loss of coherence can be explained only
if the temperature dependence of lattice parameters is considered. V2O3 is therefore effectively driven from the
"metallic" to the "insulating" side of the Mott transition as the temperature is increased.
