Lighting Through A Wall Experiment

Light shining through a wall setup.

Lighting through a wall experiment.

The idea behind the double slit experiment is that even if the photons are sent through the slits one at a time there s still a wave present to produce the interference pattern. Recently axionlike particle search has received renewed interest. In particular several groups have started light shining through a wall experiments based on magnetic field and laser both continuous which is very demanding in terms of detector background. Like the wimps the suspected particle does not belong to the standard model of particle physics nor is it clear that it actually exists.

In this paper we have described and characterized our apparatus and demonstrated the data analysis procedures. To leading order we find that when the photon frequency ωis very close to the axion mass m there is a threshold cusp. The analysis of light shining through a wall experiments. Unfortunately with present and near future technologies the opportunity to observe light shining through walls via these effects is completely out of question.

The alps collaboration runs a light shining through a wall lsw experiment to search for photon oscillations into weakly interacting sub ev particles wisps inside of a superconducting hera dipole magnet at the site of desy. Nevertheless there are quite a number of experimental collaborations around. And two recent optical laser lsw experiments have reported preliminary results. The experiment is to search for particles that can shine light through a wall.

An example of this is the so called axion. In modern physics the double slit experiment is a demonstration that light and matter can display characteristics of both classically defined waves and particles. However very feeble gravitational and electroweak effects allow for this exotic possibility. The wavy line indicates the photon field and the dashed line the axion field.

At first glance this sounds crazy. Shining light through walls. This type of experiment was first performed using light by thomas young in 1801 as a demonstration of the wave behavior of light. Moreover it displays the fundamentally probabilistic nature of quantum mechanical phenomena.
