Query: First-Order Insulator-to-Metal Mott Transition in the Paramagnetic 3D
  System GaTa4Se8   The nature of the Mott transition in the absence of any symmetry braking
remains a matter of debate. We study the correlation-driven insulator-to-metal
transition in the prototypical 3D Mott system GaTa4Se8, as a function of
temperature and applied pressure. We report novel experiments on single
crystals, which demonstrate that the transition is of first order and follows
from the coexistence of two states, one insulating and one metallic, that we
toggle with a small bias current. We provide support for our findings by
contrasting the experimental data with calculations that combine local density
approximation with dynamical mean-field theory, which are in very good
agreement.
