Zero-Dimensional PT-Symmetric Systems

Theorists at the QCN proposed that a model equation for the investigation of classical PT symmetry in zero dimensions, realized by a simple harmonic oscillator with matched time-dependent gain and loss that exhibits a transition from oscillatory to diverging motion. This behavior is similar to a transition from the exact to the broken PT phase in higher- dimensional PT-symmetric systems, with a phase diagram with alternating stable and unstable regions.
