Nevertheless there are quite a number of experimental collaborations around.
Lighting through a wall experiment.
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.
To leading order we find that when the photon frequency ωis very close to the axion mass m there is a threshold cusp.
Recently axionlike particle search has received renewed interest.
Light shining through a wall setup.
Several different calculational methods are employed and compared and in all cases we retain a nonzero axion mass.
The analysis of light shining through a wall experiments.
An example of this is the so called axion.
This type of experiment was first performed using light by thomas young in 1801 as a demonstration of the wave behavior of light.
At first glance this sounds crazy.
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.
The wavy line indicates the photon field and the dashed line the axion field.
An x ray version of this experiment has recently been proposed by rabadán et al.
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.
The experiment is to search for particles that can shine light through a wall.
Shining light through walls.
In modern physics the double slit experiment is a demonstration that light and matter can display characteristics of both classically defined waves and particles.
And two recent optical laser lsw experiments have reported preliminary results.
However very feeble gravitational and electroweak effects allow for this exotic possibility.
We present here the 2sigma limits obtained so far with our novel setup consisting of a pulsed magnetic field and a pulsed laser.
Moreover it displays the fundamentally probabilistic nature of quantum mechanical phenomena.
