Potential of the neutron Lloyd's mirror interferometer for the search for new interactions

Understand

We discuss the potential of the neutron Lloyd's mirror interferometer in a search for new interactions at small scales.

• We consider three hypothetical interactions that may be tested using the interferometer.
• The chameleon scalar field proposed to solve the enigma of accelerating expansion of the Universe produces interaction between particles and matter.
• The axion-like spin-dependent coupling between neutron and nuclei or/and electrons may cause P- and T-non-invariant interaction with matter.
