Tunneling catastrophes of the partition function
C. A. A. de Carvalho, R. M. Cavalcanti
We use path-integrals to derive a general expression for the semiclassical approximation to the partition function of a one-dimensional quantum-mechanical system. Our expression de…

Exact Green's functions for delta-function potentials and renormalization in quantum mechanics
R. M. Cavalcanti
We present a simple recipe to construct the Green's function associated with a Hamiltonian of the form H=H_0+V, where H_0 is a Hamiltonian for which the associated Green's function…
