具有两类粒子的可积BC(n)Sutherland模型

An integrable BC(n) Sutherland model with two types of particles

V. Ayadi, L. Feher

摘要:

利用SU(n,n)群上自由测地线运动的Hamilton约化,导出了一个包含三个独立耦合常数的双曲BC(n)Sutherland模型.由SU(n,n)的两个可交换对合的不动点子群的直积给出了这种约化的对称群。推导意味着可积的模型,并产生一个简单的算法来构建其解决方案。

英文摘要:

A hyperbolic BC(n) Sutherland model involving three independent coupling constants that characterize the interactions of two types of particles moving on the half-line is derived by Hamiltonian reduction of the free geodesic motion on the group SU(n,n). The symmetry group underlying the reduction is provided by the direct product of the fixed point subgroups of two commuting involutions of SU(n,n). The derivation implies the integrability of the model and yields a simple algorithm for constructing its solutions.
