Description:
Author(s): F. Rose and N. Dupuis We compute the zero-temperature conductivity in the two-dimensional quantum O ( N ) model using a nonperturbative functional renormalization-group approach. At the quantum critical point we find a universal conductivity σ * / σ Q (with σ Q = q 2 / h the quantum of conductance and q the charge) in reasonable quan... [Phys. Rev.
