SUSY partners of the truncated oscillator, Painlevé transcendents and Bäcklund transformations (1603.05173v1)

Abstract: In this work the supersymmetric technique is applied to the truncated oscillator to generate Hamiltonians ruled by second and third-order polynomial Heisenberg algebras, which are connected to the Painlev\'e IV and Painlev\'e V equations respectively. The aforementioned connection is exploited to produce particular solutions to both non-linear differential equations and the B\"acklund transformations relating them.
