Contact Interactions and Gamma Convergence
We introduce contact interactions defined by boundary conditions at the contact manifold Γ≡∪i, j{xi = xj}. There are two types of contact interactions, weak and strong. Both provide self-adjoint extensions of Ĥ0 the free hamiltonian restricted away from Γ. We analyze both of them by “lifting” the sy...
