“…[11]), which uses the motional effects of radiation pressure to cool mechanical degrees of freedom to sub-Kelvin temperatures [12][13][14], and even close to the quantum ground state [15]. Relevant to this is work on "radiation damping" [16,17] in highly dispersive systems such as photonic crystals [18] and atomic multilayers [19]. This paper adds to other recent work on velocity-dependent forces in optomechanics [20], generalizing such treatments to an arbitrary direction of motion.…”

Radiation pressure in stratified moving media

A general theory of optical forces on moving bodies is here developed in terms of generalized 4 × 4 transfer and scattering matrices. Results are presented for a planar dielectric of arbitrary refractive index placed in an otherwise empty space and moving parallel and perpendicular to the slab-vacuum interface. In both regimes of motion the resulting force comprises lateral and normal velocity-dependent components, which may depend in a subtle way on the Doppler effect and s-p-polarization mixing. For lateral displacements in particular, polarization mixing, which is here interpreted as an effective magnetoelectric effect due to the reduced symmetry induced by the motion of the slab, gives rise to a velocity-dependent force contribution that is sensitive to the phase difference between the two polarization amplitudes. This term gives rise to a rather peculiar optical response on the moving body, and specific cases are illustrated for incident radiation of arbitrarily directed linear polarization. The additional force due to polarization mixing may cancel to first order in V /c with the first order Doppler contribution yielding an overall vanishing of the velocity-dependent component of the force on the body. The above findings bear some relevance to modern developments of nano-optomechanics and to the problem of the frictional component of the Casimir force.

“…[6,9] vacuum squeezing was predicted/observed for very high laser intensity comparable with hyperfine splitting of the 87 Rb ground state (∼ 6.8 GHz). Under such conditions the influence of atomic coherence on nonlinear properties of an atomic vapor is insignificant [16]. Under such conditions the D 1 transition of 87 Rb can be treated as a two-level system J = 1/2 → J ′ = 1/2, where nonlinear circular birefringence occurs due to optical pumping.…”

We present experimental study of polarization quantum noise of laser radiation passed through optically think vapor of Rb 87 . We observe a step-like noise spectrum. We discuss various factor which may result in such noise spectrum and prevent observation of squeezing of quantum fluctuations predicted in Matsko et al, Phys. Rev. A 63, 043814 (2001).PACS numbers: 42.50. Gy, 42.65.Ky The sensitivity of many experiments is ultimately limited by quantum fluctuations of electromagnetic field. This stimulates the development of various methods for generation of light with non-classical statistics ("squeezed light"). Usage of such light field in an experiment often allows measurement noise reduction below shot noise limit [1,2]. Photon statistics modification often requires nonlinear optical medium; the degree of change depends on the strength of the nonlinear effects and linear losses in such medium [2,3].Recent proposals of photon statistics control based on coherent atomic vapor look quite promising from that point of view. Atomic coherence created between two hyperfine ground states of an alkali metal by a strong classical control field eliminates linear absorption and simultaneously produces strong nonlinear dispersion for a weak probe field (classical or quantized). This effect is known as electromagnetically induced transparency (EIT) [1]. Third-order nonlinear susceptibility in an EIT medium is substantial and comparable with linear susceptibility, which enhances coupling between electromagnetic fields participating in such nonlinear processes [4]. Ref. [5] demonstrated effective projection of photon quantum state on collective spin excitation of an atomic ensemble under EIT condition, long storage time, and the ondemand retrieval of quantum information.Matsko et al.[6] predicted squeezing of vacuum quantum fluctuations for laser light propagating through an EIT medium with coherence between Zeeman states of the same hyperfine atomic sublevel. Theoretical calculations estimated squeezing up to 8dB under realistic experimental conditions.The main purpose of this work was to study the polarization quantum noise of laser radiation for the D 1 line of Rb and to explore the possibility for squeezed vacuum observation on that transition. In particular, we studied the relation between laser intensity and the bandwidth of laser-induced quantum noise.The mechanism of polarization quantum noise squeezing proposed in [6] is the following: linearly polarized laser radiation is decomposed into two circularly polarized components σ + and σ − , as shown in Fig. 1(a), which form a Λ system and create coherence between |m F = −1 and |m F = +1 Zeeman sublevels, producing EIT. In an ideal three-level Λ system phase difference for two circularly polarized components does not change after interaction with atoms. However, under realistic conditions interaction of light with additional atomic levels (in particular with the other far-detuned hyperfine sublevel(s) of the excited state), Doppler effect, optical losses, etc., causes...

“…Radiation pressure arises from the momentum of light and depends upon the velocity of the body being pushed [1,2]. Take light incident onto the surface of a perfectly reflecting mirror that moves along the surface normal; in the mirror rest frame, the momentum and rate of arrival of the incident photons will appear either increased or decreased relative to the laboratory, depending on whether the mirror moves toward, or away from, the light source.…”

The dependence of macroscopic radiation pressure on the velocity of the object being pushed is commonly attributed to the Doppler effect. This need not be the case, and here we highlight velocity-dependent radiation pressure terms that have their origins in the mixing of s and p polarizations brought about by the Lorentz transformation between the lab and the material rest frame, rather than in the corresponding transformation of frequency and wavevector. The theory we develop may be relevant to the nano-optomechanics of moving bodies.
