Query: Quantum criticality of the two-channel pseudogap Anderson model:
  Universal scaling in linear and non-linear conductance   The quantum criticality of the two-lead two-channel pseudogap Anderson model
is studied. Based on the non-crossing approximation, we calculate both the
linear and nonlinear conductance of the model at finite temperatures with a
voltage bias and a power-law vanishing conduction electron density of states,
$\propto |\omega-\mu_F|^r$ ($0<r<1$) near the Fermi energy. Equilibrium and
non-equilibrium quantum critical properties at the two-channel Kondo (2CK) to
local moment (LM) phase transition are addressed by extracting universal
scaling functions in both linear and non-linear conductances, respectively.
Clear distinctions are found on the critical exponents between linear and
non-linear conductance. The implications of these two distinct quantum critical
properties for the non-equilibrium quantum criticality in general are
discussed.
