Systems of coupled PT-symmetric oscillators

Carl M. Bender, Mariagiovanna Gianfreda, S. P. Klevansky

The Hamiltonian for a PT-symmetric chain of coupled oscillators is constructed. It is shown that if the loss-gain parameter $γ$ is uniform for all oscillators, then as the number o…

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…
