关于共形力学的Schwarzian对应体

On the Schwarzian counterparts of conformal mechanics

Sergei Filyukov, Ivan Masterov

摘要:

研究表明,如果Schwarzian力学(SM)中的能量等于de Alfaro-Fubini-Furlan(DAFF)模型中的耦合常数,则这两个系统之间存在联系.特别地,SM的运动方程、SL(2,R)对称变换和相应的守恒电荷可以通过应用一种特殊类型的坐标变换从DAFF模型的那些导出,而DAFF系统的通解映射到SM的速度函数。通过非线性实现的方法来重现这种联系。在牛顿-胡克(NH)时空的DAFF力学的Schwarzian同行以及DAFF模型的高阶导数的推广进行了讨论。

英文摘要:

It is shown that, if the energy in the Schwarzian mechanics (SM) is equal to the coupling constant in the de Alfaro-Fubini-Furlan (DAFF) model, there exists a link between these two systems. In particular, the equation of motion, SL(2,R)-symmetry transformations and the corresponding conserved charges of SM can be derived from those of the DAFF model by applying a coordinate transformation of a special type, while the general solution of the DAFF system maps to the velocity function of SM. A way to reproduce this link via the method of nonlinear realizations is presented. Schwarzian counterparts of the DAFF mechanics in Newton-Hooke (NH) spacetime as well as a higher derivative generalization of the DAFF model are discussed.
