关于一维盒中的三维和一维Weyl粒子

On 3D and 1D Weyl particles in a 1D box

Salvatore De Vincenzo

摘要:

我们构建了最一般的家庭的自伴边界条件的三个(等效)外尔哈密顿算子,每个描述一个三维外尔粒子在一个一维盒子位于沿笛卡尔轴。这些结果基本上是通过使用最一般的自伴边界条件族的狄拉克哈密顿算子,描述了一个一维狄拉克粒子在一个盒子里,在外尔表示,并通过应用简单的变化表示这个操作。同样,我们提出了最一般的家庭的自伴边界条件的外尔哈密顿算子,描述了一个一维外尔粒子在一个一维的盒子。我们还获得和讨论在整个文章中不同的结果有关的外尔方程在(3+1)和(1+1)维,除了他们各自的波函数,并提出某些关键结果有关的狄拉克方程在(1+1)维的陈述。

英文摘要:

We construct the most general families of self-adjoint boundary conditions for three (equivalent) Weyl Hamiltonian operators, each describing a three-dimensional Weyl particle in a one-dimensional box situated along a Cartesian axis. These results are essentially obtained by using the most general family of self-adjoint boundary conditions for a Dirac Hamiltonian operator that describes a one-dimensional Dirac particle in a box, in the Weyl representation, and by applying simple changes of representation to this operator. Likewise, we present the most general family of self-adjoint boundary conditions for a Weyl Hamiltonian operator that describes a one-dimensional Weyl particle in a one-dimensional box. We also obtain and discuss throughout the article distinct results related to the Weyl equations in (3+1) and (1+1) dimensions, in addition to their respective wave functions, and present certain key results related to representations for the Dirac equation in (1+1) dimensions.
