Axion-like-particle search with high-intensity lasers

High Intensity Lasers in Periodontics: A Review

Background and Aim: Lasers can serve as a new powerful tool in dentistry. High intensity laser therapy is becoming the treatment of choice compared with conventional periodontal therapy due to accurate incision and soft and hard tissue ablation, hemostasis, reduction of postoperative pain and infection, optimal debridement, and enhanced healing. Although high intensity laser therapy assumes to ...

Cornering the axion-like particle explanation of quasar polarisations

In a series of paper, it has been shown that the distribution of polarisation position angles for visible light from quasars is not random in extremely large regions of the sky. As explained in a recent article, the measurement of vanishing circular polarisation for such quasars is an important problem for a mechanism involving the mixing with axionlike particles in external magnetic fields. In...

Axion search with optical technique

A brief review of particle physics motivations for axion existence is followed by a discussion of optical observables that can be used for axion detection. It is emphasised that the resonant photon axion transition can occur in the presence of low density gas bringing the experimentally accessible quantities within the reach of the present day technology.
