Exact resummation of the Holstein-Primakoff expansion and differential equation approach to operator square-roots

Michael Vogl, Pontus Laurell, Hao Zhang +2

Operator square-roots are ubiquitous in theoretical physics. They appear, for example, in the Holstein-Primakoff representation of spin operators and in the Klein-Gordon equation.…
