最小长度与量子弹跳子的非微扰研究

Minimal Length and the Quantum Bouncer: A Nonperturbative Study

Pouria Pedram

摘要:

在广义引力不确定原理(GUP)的框架下,通过量子力学和半经典方案给出了量子弹跳体的能量本征值。本文利用变形对易关系[X,P]=i \hbar(1+βP^2)的两个等价的非微扰表示,其中β是GUP参数.新的表示形式上是自伴的,并保持了位置算子的普通性质。我们发现,这两种表示结果在相同的修改后的半经典能谱,并同意与量子力学描述。

英文摘要:

We present the energy eigenvalues of a quantum bouncer in the framework of the Generalized (Gravitational) Uncertainty Principle (GUP) via quantum mechanical and semiclassical schemes. In this paper, we use two equivalent nonperturbative representations of a deformed commutation relation in the form [X,P]=i\hbar(1+βP^2) where βis the GUP parameter. The new representation is formally self-adjoint and preserves the ordinary nature of the position operator. We show that both representations result in the same modified semiclassical energy spectrum and agrees well with the quantum mechanical description.
