Many condensed matter experiments explore the finite temperature dynamics of systems near quantum critical points. Often, there are no well-defined quasiparticle excitations, and so quantum kinetic equations do not describe the transport properties completely. The theory shows that the transport co-efficients are not proportional to a mean free scattering time (as is the case in the Boltzmann theory of quasiparticles), but are completely determined by the absolute temperature and by equilibriumdoi:10.1088/0953-8984/21/16/164216 pmid:21825396 fatcat:4hrvy3oo3fbzzcn6u7lroj4kla
