非对易sine-Gordon呼吸子

The noncommutative sine-Gordon breather

Andre Fischer, Olaf Lechtenfeld

摘要:

如[hep-th/0406065]中所示,sine-Gordon模型存在非对易变形,其保持(经典)可积,但具有第二个标量场。我们采用敷料方法(适用于Moyal变形的情况)来构造变形的扭结-抗扭结和通气构型。显式的结果和绘图的领先的非交换性修正呼吸。其时间周期性不变。

英文摘要:

As shown in [hep-th/0406065], there exists a noncommutative deformation of the sine-Gordon model which remains (classically) integrable but features a second scalar field. We employ the dressing method (adapted to the Moyal-deformed situation) for constructing the deformed kink-antikink and breather configurations. Explicit results and plots are presented for the leading noncommutativity correction to the breather. Its temporal periodicity is unchanged.
