Renormalisation in Quantum Mechanics, Quantum Instantons and Quantum Chaos
arXiv:quant-ph/0102032
Abstract
We suggest how to construct non-perturbatively a renormalized action in quantum mechanics. We discuss similarties and differences with the standard effective action. We propose that the new quantum action is suitable to define and compute quantum instantons and quantum chaos.
