We study the spontaneous excitation of a two-level atom in the presence of a perfectly reflecting mirror, when the atom, or the mirror, is uniformly accelerating in the framework of the generalized uncertainty principle (GUP). The quantized scalar field obeys a modified dispersion relation leading to a GUP deformed Klein-Gordon equation. The solutions of this equation with suitable boundary conditions are obtained to calculate the spontaneous excitation probability of the atom for the two separate cases. We show that in the case when the mirror is accelerating, the GUP modulates the spatial oscillation of the excitation probability of the atom, thus breaking the symmetry between the excitation of an atom accelerating relative to a stationary mirror, and a stationary atom excited by an accelerating mirror. An explicit violation of the equivalence principle seems to be thus manifested. We further obtain an upper bound on the GUP parameter using standard values of the system parameters.

广义不确定性原理框架中加速原子镜系统中的等价性违反
我们研究了当原子或镜子在广义不确定性原理 (GUP) 的框架内均匀加速时,在完美反射镜存在下两能级原子的自发激发。量化标量场服从导致 GUP 变形的 Klein-Gordon 方程的修正色散关系。获得具有合适边界条件的该方程的解,以计算两种不同情况下原子的自发激发概率。我们表明,在反射镜加速的情况下,GUP 调制原子激发概率的空间振荡,从而打破了相对于静止反射镜加速的原子的激发与被静止原子激发的静止原子之间的对称性。加速镜。对等价原则的明显违反似乎由此表现出来。我们使用系统参数的标准值进一步获得 GUP 参数的上限。
