SNUTP 97-072 Production of photons by the parametric resonance in the dynamical Casimir effect
نویسندگان
چکیده
We calculate the number of photons produced by the parametric resonance in a cavity with vibrating walls. We consider the case that the frequency of vibrating wall is nω1(n = 1, 2, 3, ...) which is a generalization of other works considering only 2ω1, where ω1 is the fundamental-mode frequency of the electromagnetic field in the cavity. For the calculation of time-evolution of quantum fields, we introduce a new method which is borrowed from the time-dependent perturbation theory of the usual quantum mechanics. This perturbation method makes it possible to calculate the photon number for any n and to observe clearly the effect of the parametric resonance. 03.65.Ca, 03.65.-w, 42.50.Dv Typeset using REVTEX Electronic address: [email protected] Electronic address: [email protected] Electronic address: [email protected] Electronic address: [email protected] 1

متن کاملDynamical Casimir effect with cylindrical waveguides
I consider the quantum electromagnetic field in a coaxial cylindrical waveguide, such that the outer cylindrical surface has a time-dependent radius. The field propagates parallel to the axis, inside the annular region between the two cylindrical surfaces. When the mechanical frequency and the thickness of the annular region are small enough, only Transverse Electromagnetic (TEM) photons may be...
متن کاملDynamical Casimir effect in a Josephson metamaterial
The zero-point energy stored in the modes of an electromagnetic cavity has experimentally detectable effects, giving rise to an attractive interaction between the opposite walls, the static Casimir effect. A dynamical version of this effect was predicted to occur when the vacuum energy is changed either by moving the walls of the cavity or by changing the index of refraction, resulting in the c...
متن کاملOkhep–98–11 Sonoluminescence and the Dynamical Casimir Effect
It has been suggested by various authors that the ‘dynamical Casimir effect’ might prove responsible for the production of visible-light photons in the bubble collapse which occurs in sonoluminescence. Previously, I have argued against this point of view based on energetic considerations, in the adiabatic approximation. Those arguments have recently been strengthened by the demonstration of the...
متن کاملPhoton production from the vacuum close to the superradiant transition: linking the dynamical Casimir effect to the Kibble-Zurek mechanism.
The dynamical Casimir effect (DCE) predicts the generation of photons from the vacuum due to the parametric amplification of the quantum fluctuations of an electromagnetic field. The verification of such an effect is still elusive in optical systems due to the very demanding requirements of its experimental implementation. We show that an ensemble of two-level atoms collectively coupled to the ...
