Relocalization switch in a triple quantum dot molecule in 2D

Abstract

Tunneling between pronounced minima of a polynomial potential (simulating coupled quantum dots) can cause an abrupt quantum-catastrophic relocalization of density $|\psi (x,y,\dots )|$. Non-numerical illustration is constructed, in 2D, using a non-separable sextic-oscillator model.
