Dear Admin,
What is the physical meaning of effective potential in QATK? I understand it is the potential in the Hamiltonian of system, however it is difficult to understand what do all the crust and trough mean? or what is the eff. pot actually represent in a system?
I have attached a pic from a paper. This paper mentions relative difference between maximas at interface as tunneling barrier.
