摘要：
我们研究了均匀扭应力背景如何模拟连续的螺旋位错密度，并诱导有效的空间非交换性并重塑自由量子粒子的能量谱。在缺陷几何理论中，度量会产生一种一阶（磁性类似）耦合，等同于一个有效的磁场$B_{eff}$，与$p_z Omega$成正比，其中$Omega$编码扭应力强度。在强耦合（朗道）极限下，平面坐标满足[x,y] != 0，谱组织成类似朗道能级的结构，具有轻微的电场驱动倾斜和均匀位移。因此，增加$Omega$会使系统连续趋向于平坦空间中的熟悉朗道问题，其中扭应力设定非交换性尺度并控制向朗道极限的趋近。
英文摘要：
We study how a uniform torsion background, modeling a continuous density of screw dislocations and induces effective spatial noncommutativity and reshapes the energy spectrum of a free quantum particle. Within the geometric theory of defects, the metric yields a first-order (magnetic-like) coupling in the transverse dynamics, equivalent to an effective magnetic field $B_{eff}$ proportional to $p_z Omega$, where $Omega$ encodes the torsion strength. In the strong-coupling (Landau) regime, the planar coordinates obey [x,y] != 0 and the spectrum organizes into Landau-like levels with a slight electric-field-driven tilt and a uniform shift. Thus, increasing $Omega$ drives the system continuously toward the familiar Landau problem in flat space, with torsion setting the noncommutativity scale and controlling the approach to the Landau limit.
