Exact Semiclassical Dynamics in a Multidimensional Quartic Potential: Multi-Flavor Instantons and Pre-Factor Dominance at Strong Coupling
Pervez Hoodbhoy, M. Haashir Ismail, M. Mufassir
We present an exact semi-classical analysis of a coupled multi-degree-of-freedom quantum system governed by a symmetric quartic potential with four degenerate minima. Starting from…

Coupled Instantons In A Four-Well Potential With Application To The Tunneling Of A Composite Particle
Pervez Hoodbhoy, M. Haashir Ismail, M. Mufassir
Coupled instantons are introduced by generalizing the double well potential to multiple mutually coupled wells. Physically this corresponds to the simultaneous tunneling of multipl…
