Strongly coupled chameleon fields: Possible test with a neutron Lloydʼs mirror interferometer

The consideration of possible neutron Lloydʼs mirror interferometer experiment to search for strongly coupled chameleon fields is presented. The chameleon scalar fields were proposed to explain the acceleration of expansion of the Universe. The presence of a chameleon field results in a change of a particleʼs potential energy in vicinity of a massive body. This interaction causes a phase shift of neutron waves in the interferometer. The sensitivity of the method is estimated.
