Exponents and front fluctuations in the quenched Kardar-Parisi-Zhang universality class of one- and two- dimensional interfaces
Numerical simulations of quenched KPZ interfaces in 1D and 2D confirm the directed percolation depinning exponents and show non-Gaussian front fluctuation PDFs that differ from time-dependent KPZ noise.
