Minimal length in quantum mechanics and non-Hermitian Hamiltonian systems

Bagchi, B. & Fring, A. (2009). Minimal length in quantum mechanics and non-Hermitian Hamiltonian systems. Physics Letters A, 373(47), pp. 4307-4310. doi: 10.1016/j.physleta.2009.09.054

Abstract

Deformations of the canonical commutation relations lead to non-Hermitian momentum and position operators and therefore almost inevitably to non-Hermitian Hamiltonians. We demonstrate that such type of deformed quantum mechanical systems may be treated in a similar framework as quasi/pseudo and/or PT-symmetric systems, which have recently attracted much attention. For a newly proposed deformation of exponential type we compute the minimal uncertainty and minimal length, which are essential in almost all approaches to quantum gravity.
