We construct gray soliton configurations, which move at constant speeds, inholographic superfluids for the first time. Since there should be nodissipation for a moving soliton to exist, we use the simplest holographicsuperfluid model at zero temperature, considering both the standard andalternative quantizations. For comparison purpose, we first investigate blacksolitons in the zero temperature holographic superfluids, which are staticconfigurations. Then we focus on the numerical construction of gray solitonsunder both quantizations, which interpolate between the (static) black solitonsand sound waves (moving at the speed of sound). Interestingly, under thestandard quantization, a peculiar oscillation of the soliton configurations isobserved, very much resembling the Friedel oscillation in fermionic superfluidsat the BCS regime. Some implications and other aspects of the solitonconfigurations are also discussed.
