Overcoming the thermal regime for the electric-field driven Mott transition in vanadium sesquioxide

Thermal effects limit the speed of the electrically driven insulator-metal transition in V2O3 to tens of picoseconds. Here the authors show that under an intense THz-electric-field excitation the thermal regime can be overcome, achieving a purely electronic transition on ultrafast timescales.
