标题： Confining proprties of a gas of Z(2) vortices

摘要： 研究了在SO(3)规范理论自发破缺为SO(2)时的涡旋解。 这些涡旋具有Z(2)磁荷。 考虑涡旋-涡旋相互作用，研究了Z(2)涡旋的稀薄气体。 通过转换到对偶表示，我们表明奇数电荷被弦张力束缚，该弦张力随反耦合的指数衰减。 显示英文摘要

摘要： Vortex solutions are studied in an SO(3) gauge theory spontaneously broken to SO(2). These vortices have a Z(2) magnetic charge. A dilute gas of Z(2) vortices is studied taking into account vortex-vortex interactions. By going to a dual representation we show that odd charges are confined with a string tension which decreases exponentially with the inverse coupling.
