Corrections induced by the GUP to the Lamb shift of an accelerated atom interacting with a quantum scalar field
Zhi Wang, Yi Yang, Zhengwen Long
We investigate the effect of the GUP on the Lamb shift of a two-level atom interacting with a real massless scalar quantum field, within the DDC formalism. For an atom undergoing i…
