WebFEP is often discussed in terms of two types of calculation: Absolute Free Energy Perturbation, which calculates the binding event of a solvated ligand into a protein target. Relative Free Energy of binding (RFEB), … WebMar 24, 2024 · Perturbation Theory and Thermodynamic Limit. Suppose we have a classical Hamiltonian that can be divided into an “easy” part H0 and a “difficult” part ΔH that depends on a parameter g: H = H0 + gΔH . because it's a classical system so H0 and ΔH commute. The partition function of the easy part,
