Field theory of disordered elastic interfaces at 3-loop order: Critical exponents and scaling functions

2018 
Abstract For disordered elastic manifolds in the ground state (equilibrium) we obtain the critical exponents for the roughness and the correction-to-scaling up to 3-loop order, i.e. third order in e = 4 − d , where d is the internal dimension d . We also give the full 2-point function up to order e 2 , i.e. at 2-loop order.
