Vacuum Polarization Effects from Fermion Zero-Point Energy

The influence of an external electromagnetic field on the vacuum structure of a quantized Dirac field is investigated by considering the quantum corrections to classical Maxwell’s Lagrangian density induced by fluctuations of the non-perturbative vacuum. Effective Lagrangian densities for Maxwell’s theory in (3+1) and (2+1) dimensions are derived from the vacuum zero-point energy of the fermion...

Energy and Thermodynamic Considerations Involving Electromagnetic Zero-Point Radiation

There has been recent speculation and controversy regarding whether electromagnetic zero-point radiation might be the next candidate in the progression of plentiful energy sources, ranging, for example, from hydrodynamic, chemical, and nuclear energy sources. Certainly, however, extracting energy from the vacuum seems counter intuitive to most people. Here, these ideas are clarified, drawing on...

Comment on contributions of fundamental particles to the vacuum energy

This is the comment to the preprints by G. Ossola and A. Sirlin, hep-ph/0305050, and E.Kh. Akhmedov, hep-th/0204048, who discussed different regularization schemes for calculations of the vacuum energy stored in the zero-point motion of fundamental fields. We show that the contribution of the fermionic and bosonic fields to the energy of the vacuum depends on the physical realization of the vac...

Quantum Vacuum Fluctuations, Zero Point Energy and the Question of Observable Noise

Reviewing the Zero Point Energy

A review of recent developments in the study of the Zero Point Energy (ZPE) is made. The origin and behavior of the electromagnetic fields making up the vacuum ZPE is elucidated. From this it is deduced that the ZPE should increase with time even in a static universe such as Narliker and Arp propose. The small oscillations that a static cosmos undergoes will add a variable component to the over...
