Infrared properties of two-dimensional $\mathrm{SU}(N)/H$ nonlinear $\ddot{I}ƒ$ models at nonzero $\hat{I}¸$ angles

Philippe Lecheminant, Yuya Tanizaki, Keisuke Totsuka

A general strategy is proposed to explore the low-energy properties of two-dimensional nonlinear $\ddot{I}ƒ$ models with $\hat{I}¸$ terms. We demonstrate its application to nonlinear $\ddot{I}ƒ$ model…
