| Abstract: | We propose a novel idea to discover millicharged particles (mCPs) captured by the earth during its existence. It has been demonstrated that the mCPs accumulation inside the earth leads to the enhancement of its number density much larger than the corresponding virial density. We propose to utilize an unconventional laser interferometer to probe these earth-bound mCPs through the detection of the photons's phase shift. We demonstrate that, for mCPs mass in the range between 1 GeV to 10 12 GeV, the sensitivity of probing their fractional electric charge ϵ could reach as low as 10 - 12 to 10 - 6 provided that mCPs number density is greater than 1 cm - 3 and the interferometer operates at the Heisenberg limit.
