摘要:

重子激发的一个示意性的模型中提出的对称狄拉克陀螺仪,一个相对论模型可解的封闭形式,减少到转子的非相对论性限制。然后将该模型映射到最近邻紧束缚模型上。在最简单的一维形式中,该模型产生有限的等距谱。这是实验实现为一个链的介质谐振器的条件下,他们的耦合是倏逝和良好的协议与预测实现。

英文摘要:

A schematic model for baryon excitations is presented in terms of a symmetric Dirac gyroscope, a relativistic model solvable in closed form, that reduces to a rotor in the non-relativistic limit. The model is then mapped on a nearest neighbour tight binding model. In its simplest one-dimensional form this model yields a finite equidistant spectrum. This is experimentally implemented as a chain of dielectric resonators under conditions where their coupling is evanescent and good agreement with the prediction is achieved.
