Calculating the free energy difference by applying the Jarzynski equality to a virtual integrable system
Calculating the free energy difference by applying the Jarzynski equality to a virtual integrable system
The Jarzynski equality (JE) provides a nonequilibrium method to measure and calculate the free energy difference (FED). Note that if two systems share the same Hamiltonian at two equilibrium states, respectively, they share the same FED between these two equilibrium states as well. Therefore the calculation of the FED of …
