Abstract

We study the Dicke-type crossings among eigenvalues of a type of differential operators describing the noncommutative oscillator in a class. This class consists of some matrix-valued Schrödinger operators. We will show how the crossings occur for the differential operators in detail. In particular, we are interested in the crossing between the ground state energy and an excited state energy.
