Analogue gravity from field theory normal modes?
... This could be used, for instance, to simplify the potential term at the cost of self-adjointness. Generically, one would wish to preserve formal self-adjointness even at the cost of a more complicated potential term, but we emphasize that at the level of causality there is no strong reason for makin ...

Chapter 12 Path Integral for Fermion Fields
... After introducing path integrals in quantum mechanics we now turn to the path integral representation of field theories. In this chapter we discuss the fermionic sector of the Schwinger model, which is probably the simplest non-trivial field theory. The Schwinger model is just QED for massless fermi ...

... The dynamics of an electron in a Coulomb potential and static fields has been extensively studied using quantum and semiclassical techniques. The quantum calculations are relatively simple to perform for low-n states, but become increasingly difficult and less accurate as n increases. Semiclassical ...
