Quantum theory of an electromagnetic observer: classically behaving macroscopic systems and emergence of classical world in quantum electrodynamics
L. I. Plimak, Misha Ivanov, A. Aiello +1
Quantum electrodynamics under conditions of distinguishability of interacting matter entities, and of controlled actions and back-actions between them, is considered. Such "mesosco…
Causal signal transmission by quantum fields -- V: Generalised Keldysh rotations and electromagnetic response of the Dirac sea
L I Plimak, S Stenholm
The connection between real-time quantum field theory (RTQFT) [see, e.g., A.\ Kamenev and A.\ Levchenko, Advances in Physics {58} (2009) 197] and phase-space techniques [E.\ Wolf a…
Causal signal transmission by quantum fields. Electromagnetic interaction of distinguishable devices and the optical equivalence theorem
L. I. Plimak, S. Stenholm
Generalised phase-space techniques for electromagnetic interactions beyond the rotating wave approximation [L.P. and S.S., arXiv:1104.3825 (2011)] is applied to interactions of dis…
Operator ordering and causality
L. I. Plimak, S. T. Stenholm
It is shown that causality violations [M. de Haan, Physica 132A, 375, 397 (1985)], emerging when the conventional definition of the time-normal operator ordering [P.L.Kelley and W.…
Causal signal transmission by quantum fields. Phase-space approach to quantum electrodynamics
L. I. Plimak, S. Stenholm
Phase-space techniques are generalized to nonlinear quantum electrodynamics beyond the rotating wave approximation, resulting in an essentially classical picture of radiation dynam…
Causal signal transmission by quantum fields. Quantum electrodynamics in response representation
L. I. Plimak, S. T. Stenholm
Using electromagnetic interaction as an example, response transformations [L.P. and S.S., Ann.Phys. 323, 1963, 1989 (2008), 324, 600 (2009)] are applied to the standard perturbativ…
