- Abstract: A recent proposal describes space based gravitational wave (GW) detection
with optical lattice atomic clocks [Kolkowitz et. al., Phys. Rev. D 94, 124043
(2016)] [1]. Based on their setup, we propose a new measurement method for
gravitational wave detection in low frequency with optical lattice atomic
clocks. In our method, n successive Doppler signals are collected and the
summation for all these signals is made to improve the sensitivity of the
low-frequency GW detection. In particular, the improvement is adjustable by the
number of Doppler signals, which is equivalent to that the length between two
atomic clocks is increased. Thus, the same sensitivity can be reached but with
shorter distance, even though the acceleration noises lead to failing to
achieve the anticipated improvement below the inflection point of frequency
which is determined by the quantum projection noise. Our result is timely for
the ongoing development of space-born observatories aimed at studying physical
and astrophysical effects associated with low-frequency GW.
