Periodic Instantons and Quantum-Classical Transitions in Spin Systems

J. -Q. Liang, H. J. W. Mueller-Kirsten, D. K. Park +1

Some models allowing explicit calculation of periodic instantons and evaluation of their action are studied with regard to transitions from classical to quantum behaviour as the te…
