Summary
Coupled nonlinear Schrödinger (NLS) equations is an ubiquitous model\\ndescribing wave propagation in diverse physical systems. In combination with\\ngain and loss exactly balanced with each other, this model allows for modeling\\nparity (P) and time (T ) symmetries in frameworks beyond the non-Hermitian\\nquantum mechanics, where they have been introduced originally. Being open, i.e.\\nnot conserving energy, such systems nevertheless bear many properties which are\\ncharacteristic for conservative models. This allows one to explore various wave\\nphenomena in PT -symmetric settings, including bright and dark solitons and\\ntheir interactions with defects, soliton switches, resonant wave interactions, wave\\ncollapse, etc. In this Chapter an overview of some recent results on these processes\\nis presented. The outcomes are interpreted in contexts of nonlinear optics and matter\\nwave theory.
