非对易性作为非等价量子化的度量

Non-commutativity as a measure of inequivalent quantization

Pulak Ranjan Giri

摘要:

我们表明,强度的非交换性可以发挥作用,在确定边界条件的物理问题。作为一个玩具模型,我们考虑非交换空间中的平方反问题。已知系统的标度不变性被非交换性的标度θ明确地打破。在非交换空间中的问题进行了分析。结果表明,尽管存在由势在Θ中的一阶展开的首项所产生的高阶奇异势,但它仍可以有自伴扩张.得到的边界条件属于一个单参数族,且与非交换性的强度有关。

英文摘要:

We show that the strength of non-commutativity could play a role in determining the boundary condition of a physical problem. As a toy model we consider the inverse square problem in non-commutative space. The scale invariance of the system is known to be explicitly broken by the scale of non-commutativity Θ. The resulting problem in non-commutative space is analyzed. It is shown that despite the presence of higher singular potential coming from the leading term of the expansion of the potential to first order in Θ, it can have a self-adjoint extensions. The boundary conditions are obtained, belong to a 1-parameter family and related to the strength of non-commutativity.
