Effect of atomic state measurement on squeezing of the field

Using the theory of ideal quantum measurements as a basis, we show that the atomic state measurement has a great effect on squeezing of the field in the Jaynes-Cummings model.Received 7 February 1989DOI:https://doi.org/10.1103/PhysRevA.40.4797©1989 American Physical Society

Maximal velocity of photons in non-relativistic QED

Jean‐François Bony, Jérémy Faupin, Israel Michael Sigal

We consider the problem of propagation of photons in the quantum theory of non-relativistic matter coupled to electromagnetic radiation, which is, presently, the only consistent quantum theory of matter and radiation. Assuming that the matter system is in a localized state (i.e for energies below the ionization threshold), we show that the probability to find photons at time t at the distance greater than ct, where c is the speed of light, vanishes as t goes to infinity as an inverse power of t.

Measurement of the velocity of a Dirac particle

P. C. W. Davies

Using a model quantum clock, the author shows how the velocity of a relativistic particle can be measured. The results are used to analyse the long-standing problem of the velocity of a Dirac particle.

On the Fermionic Quasi-particle Interpretation in Minimal Models of Conformal Field Theory

Alexander A. Belavin, A. (Freie Univ. Berlin (Germany). Inst. fuer Theoretische Physik) Fring, Technische Univ. Berlin (Germany). Sonderforschungsbereich 288 -Differentialgeometrie und Quantenphysik

The conjecture that the states of the ferminonic quasi-particles in minimal conformal field theories are eigenstates of the integrals of motion to certain eigenvalues is checked and shown to be correct only for the Ising model.
