Continuing our earlier work on the application of Relativistic Generalized Uncertainty Principle (RGUP) to quantum field theories, in this paper we study Quantum Electrodynamics (QED) with minimum length. We obtain expressions for Lagrangian, Feynman rules and scattering amplitudes theory, discuss their consequences current future high energy physics experiments. hope will provide an improved w...

In this work we have considered a simple mechanical oscillator interacting with single mode optical field inside cavity in the generalized uncertainty principle framework (GUP). Our aim is to calculate modified noise spectrum and observe effects of GUP. The commutation relation that has an extra linear order momentum term along quadratic term. Confronting our theoretical results observational r...
