CPT-Symmetric Discrete Square Well
Original language description
In an addendum to the recent systematic Hermitization of certain N by N matrix Hamiltonians H ((N))(lambda) (Znojil in J. Math. Phys. 50:122105, 2009) we propose an amendment H ((N))(lambda,lambda) of the model. The gain is threefold. Firstly, the updated model acquires a natural mathematical meaning of Runge-Kutta approximant to a differential PT-symmetric square well in which P is parity. Secondly, the appeal of the model in physics is enhanced since the related operator C of the so called "charge" (the requirement of observability of which defines the most popular Bender's metric Theta = PC) becomes also obtainable (and is constructed here) in an elementary antidiagonal matrix form at all N.
