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*/σQ (with σQ=q2/h the quantum of conductance and q the charge) in reasonable quantitative agreement with quantum Monte Carlo simula...

The modern conformal bootstrap program often employs the method of linear functionals to derive the numerical or analytical bounds on the CFT data. These functionals must have a crucial “swapping” property, allowing to swap infinite summation with the action of the functional in the conformal bootstrap sum rule. Swapping is easy to justify for the ...

We discuss the 4pt function of the critical 3d Ising model, extracted fromrecent conformal bootstrap results. We focus on the non-gaussianity Q - theratio of the 4pt function to its gaussian part given by three Wickcontractions. This ratio reveals significant non-gaussianity of the criticalfluctuations. The bootstrap results are consistent with a r...
