A PT -Symmetric Dual-Core System with the Sine-Gordon Nonlinearity and Derivative Coupling
As an extension of the class of nonlinear PT -symmetric models, we propose a system of sine-Gordon equations, with the PT symmetry represented by balanced gain and loss in them. The equations are coupled by sine-field terms and first-order derivatives. The sinusoidal coupling stems from l...
