WebTypes of Boundary Conditions. The five types of boundary conditions are: Dirichlet (also called Type I), Neumann (also called Type II, Flux, or Natural), Robin (also called Type III), Mixed, Cauchy. Dirichlet and Neumann are the most common. Dirichlet: Specifies the function’s value on the boundary.

WebEquivalence of the effective Hamiltonian approach and the Siegert boundary condition for resonant states. by Naomichi Hatano. 2013, Fortschritte der Physik. Download Free PDF. WebThis is the Siegert boundary condition that the resonant state has only out-going waves away from the scatterer [6, 14, 23, 27]. In fact, the Siegert boundary condition not only supports the resonant states but all other possible discrete states including the bound states and the anti-resonant states, that is, all poles of the S matrix.
