dc.description.abstract | In the present work, we explore the case of a general PT -symmetric dimer in the context of two both linearly
and nonlinearly coupled cubic oscillators. To obtain an analytical handle on the system, we first explore the
rotating wave approximation converting it into a discrete nonlinear Schr¨odinger type dimer. In the latter context,
the stationary solutions and their stability are identified numerically but also wherever possible analytically.
Solutions stemming from both symmetric and anti-symmetric special limits are identified. A number of special
cases are explored regarding the ratio of coefficients of nonlinearity between oscillators over the intrinsic one of
each oscillator. Finally, the considerations are extended to the original oscillator model, where periodic orbits
and their stability are obtained. When the solutions are found to be unstable their dynamics is monitored by
means of direct numerical simulations. | es |
