On the effective secular equation

Francisco M. Fernández

We show that the effective secular equation proposed several years ago is suitable for estimating the location of the exceptional points of eigenvalue equations. As an illustrative…

Comment on: "On the characteristic polynomial of an effective Hamiltonian"

Francisco M. Fernández

We show that a method proposed recently, based on the characteristic polynomial of an effective Hamiltonian, had been developed several years earlier by other authors in a clearer…

Algebraic analysis of non-Hermitian quadratic Hamiltonians

Francisco M. Fernández

We study a general one-mode non-Hermitian quadratic Hamiltonian that does not exhibit -symmetry. By means of an algebraic method we determine the conditions for the e…

Extremely broken generalized symmetry

Francisco M. Fernández

We discuss some simple Hückel-like matrix representations of non-Hermitian operators with antiunitary symmetries that include generalized (parity transformation foll…
