Magnetic field path integral

Web4 apr. 2024 · But path-integral formulation says that a particle can go from a point A to B in infinitely many possible paths and we have to consider the contribution from all. Sure, but it also says there's a probability distribution that you have to apply to those paths. And when you do that, you end up with a strongly favored path that often looks classical. WebWe consider the spin boson model with external magnetic field. We prove a path integral formula for the heat kernel, known as Feynman–Kac–Nelson (FKN) formula. We use this path integral representation to express the ground state energy as a stochastic integral. Based on this connection, we determine the expansion coefficients of the ground state …
