Abstract:
Thermalization is a probabilistic process. As such, it is generally expected that when we increase the temperature of a system, its classical behavior dominates its quantum coherences. By employing the Gibbs state of a translationally invariant quantum spin liquid—Kitaev's honeycomb lattice model—we demonstrate that an insulating phase at T=0 becomes metallic purely by increasing temperature. In particular, we compute the finite-temperature distribution of energies and show that it diverges loga...     »
