Hamiltonian formulation of the standard $P T$ -symmetric nonlinear Schrödinger dimer

I. V. Barashenkov

The standard $P T$ -symmetric dimer is a linearly-coupled two-site discrete nonlinear Schrödinger equation with one site losing and the other one gaining energy at the same…

An exactly solvable $P T$ -symmetric dimer from a Hamiltonian system of nonlinear oscillators with gain and loss

I V Barashenkov, Mariagiovanna Gianfreda

We show that a pair of coupled nonlinear oscillators, of which one oscillator has positive and the other one negative damping of equal rate, can form a Hamiltonian system. Small-am…
