Assume that a stationary electron $A$ emits a virtual photon with $4$-momentum $k$ and a stationary electron $B$ absorbs it. Let us assume a description in which time is moving forwards. At the ...
Let us assume that we want to describe the full process of photon emission by electron A and absorption by electron B. Therefore electron B must be on the forward lightcone of electron A. In the ...
Is there a particular limit on the maximum amount of mass (matter and antimatter) that can be considered to be formed in free space simultaneously. I believe that for the phenomenon to occur the ...
Does the frequency of virtual particles (creation/annihilation) match with nucleus random paths - known as Quantum Brownian Motion?
Are there any other mechanisms that can make virtual particles 'real' other than Hawking Radiation and Universe Births?
As I understand it, if virtual particles do not recombine within the plank time they become 'real'. This is proposed to happen in Hawking Radiation, where one virtual particle crosses the black ...
(I'm just wondering if some of the concepts in QFT can be exported back to QM, especially the concept of virtual particle) So I've just read Arnold Neumaier's description about virtual particle in ...
