通过超空间的N=4超共形n粒子力学

N=4 superconformal n-particle mechanics via superspace

Sergey Krivonos, Olaf Lechtenfeld, Kirill Polovnikov

摘要:

我们重新审视(无扭曲)超场方法的一维多粒子系统与N=4超共形不变性。标准(平坦)玻色子动能的要求意味着惯性(超)坐标的存在,它在三个粒子之外是非平凡的。我们给出了相应的可积条件,其解直接得到超势、两个前势和玻色子势。两个前电位的结构方程,包括WDVV方程,自动遵循。给出了三粒子模型的一般解,并举例说明。对于四粒子情形,我们利用已知的WDVV解构造了一个D_3和B_3模型,从而克服了先前发现的玻色子势的障碍。一般的解决办法和分类仍然是一个挑战。

英文摘要:

We revisit the (untwisted) superfield approach to one-dimensional multi-particle systems with N=4 superconformal invariance. The requirement of a standard (flat) bosonic kinetic energy implies the existence of inertial (super-)coordinates, which is nontrivial beyond three particles. We formulate the corresponding integrability conditions, whose solution directly yields the superpotential, the two prepotentials and the bosonic potential. The structure equations for the two prepotentials, including the WDVV equation, follow automatically. The general solution for translation-invariant three-particle models is presented and illustrated with examples. For the four-particle case, we take advantage of known WDVV solutions to construct a D_3 and a B_3 model, thus overcoming a previously-found barrier regarding the bosonic potential. The general solution and classification remain a challenge.
