Towards Background-free RENP using a Photonic Crystal Waveguide

Understand

We study how to suppress multiphoton emission background in QED against radiative emission of neutrino pair (RENP) from atoms.

• We purse the possibility of background suppression using the photonic band structure of periodic dielectric media, called photonic crystals.
• The modification of photon emission rate in photonic crystal waveguides is quantitatively examined to clarify the condition of background-free RENP.
