Abstract
The paramagnetic phase of the two-channel Kondo lattice model is exami ned with a quantum Monte Carlo simulation in the limit of infinite dim ensions. We find non-Fermi-liquid behavior at low temperatures includi ng a finite low-temperature single-particle scattering rate, no Fermi distribution discontinuity, and zero Drude weight. Both the optical an d quasiparticle mass enhancement and scattering relaxation rate show c onsistent evidence of non-fermi-liquid behavior. However, the low-ener gy density of electronic states is finite.
