Non-equilibrium conductivity at quantum critical points
Quantum criticality provides an important route to revealing universal non-equilibrium behaviour. A canonical example of a quantum critical point is the Bose-Hubbard model, which we study under the application of an electric field. A Boltzmann transport formalism and ǫ-expansion are used to obtain the non-equilibrium conductivity and current noise. This approach allows us to explicitly identify...
متن کاملDeconfined quantum critical points.
The theory of second-order phase transitions is one of the foundations of modern statistical mechanics and condensed-matter theory. A central concept is the observable order parameter, whose nonzero average value characterizes one or more phases. At large distances and long times, fluctuations of the order parameter(s) are described by a continuum field theory, and these dominate the physics ne...
متن کاملFractionalized Quantum Critical Points
Groundstates of certain materials can support exotic excitations with a charge that’s a fraction of the fundamental electron charge. The condensation of these fractionalized particles has been predicted to drive novel quantum phase transitions, which haven’t yet been observed in realistic systems. Through numerical and theoretical analysis of a physical model of interacting lattice bosons, we e...
