Correlated insulator collapse due to quantum avalanche via in-gap ladder states - Nature Communications

'Quantum avalanche' explains how nonconductors turn into conductors NatureComms

behavior in the weak- and strong-coupling limits demonstrates a crossover between the quantum and thermal switching mechanisms as temperature is varied.

To conclude, we have established a quantum avalanche mechanism as a generic scenario for the nonequilibrium phase transition in correlated insulators. The proposed mechanism not only resolves the long-standing discrepancy between the observed and predicted switching fields in these materials, but also sheds new light on the origins of the crossover between the quantum and thermal scenarios in resistive transitions.
