Model pseudofermionic systems: connections with exceptional points
arXiv:1402.6201 · doi:10.1103/PhysRevA.89.032113
Abstract
We discuss the role of pseudo-fermions in the analysis of some two-dimensional models, recently introduced in connection with non self-adjoint hamiltonians. Among other aspects, we discuss the appearance of exceptional points in connection with the validity of the extended anti-commutation rules which define the pseudo-fermionic structure.
