Resumen:

It has been recently found that the propagator (Green's function of two events) of an infinite tight-binding chain can be written explicitly as a Bessel function of the first kind arXiv:1205.3972. A number of interesting physical properties can be established from a myriad of classical theorems on these functions, including a formulation in terms of Feynman path sums. In this talk we review these procedures and further extend them to hexagonal, triangular and square lattices.
