Rotation Effects on Mesonic Condensations in Isospin Matter

Abstract

We investigate the rotation effects on the mesonic condensation in isospin matter . Using the two-flavor NJL effective model with a global rotation, we demonstrate two important effects of the rotation on its phase structure: a rotational suppression of the scalar-channel condensates, in particular the pion condensation region; and a rotational enhancement of the rho condensation region with vector-channel condensate. A new phase diagram for isospin matter under rotation is mapped out on the $\ddot{I}‰-\hat{I}{¼}_I$ plane where three distinctive phases, corresponding to $\ddot{I}ƒ$, $\ddot{I}€$, $\ddot{I}$ dominated regions respectively, are separated by a second-order line at low isospin chemical potential and a first-order line at high rotation which are further connected at a tri-critical point.
