Chiral solitons from dimensional reduction of Chern-Simons gauged non-linear Schrodinger equation: classical and quantum aspects

The soliton structure of a gauge theory recently proposed to describe two-dimensional chiral excitations is investigated. A new type of non-linear derivative Schrodinger equation emerges as an effective description of the system that supports novel chiral solitons. We discuss the classical properties of solutions with vanishing and non-vanishing boundary conditions (dark solitons) and we explain their relation to integrable systems. The quantum analysis is also addressed in the framework of a semiclassical approximation improved by renormalization group arguments
