Abstract:
Supersymmetry is a well established concept in quantum
mechanics. The prominent role is played by Witten model of N=2
supersymmetry, where Hamiltonian and supercharges are represented by
matrix operators. We will show that the genuine superalgebraic
structure can appear in a hidden form, in the systems where the
fermionic degrees of freedom are absent. We will discuss a planar
model of a spin-less particle in presence of a singular magnetic flux
as an example.
