Covariant Effective Action for Quantum Particle with Coordinate-Dependent Mass

Abstract

Using a covariant background field method we calculate the one-loop quantum effective action for a particle with coordinate-dependent mass moving slowly through a one-dimensional configuration space. The procedure can easily be extended to any desired loop order.
