What is recorded here?
Malnou and colleagues demonstrated a squeezed microwave receiver on a synthetic weak signal, reporting a 2.12 ± 0.08 scan-rate enhancement in a setup designed to mimic an axion search. The subsequent HAYSTAC experiment used related methods in a dark-matter search, reporting about a 1.9-fold gain over an optimal unsqueezed comparator and no axion signal in two selected mass windows.
Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.
Scientific scope
The 2018 prototype injected a synthetic signal into a fixed-frequency cavity with no applied magnetic field; it was not an axion detection or live astrophysical search. The later HAYSTAC gain is for its specified receiver and benchmark, and squeezing broadens sensitivity rather than improving the peak on resonance. Its aggregate constraint depends on halo and signal assumptions and omits the 4.140–4.145 GHz mode crossing; thirty-two initial excesses did not persist on rescan. Two semi-independent internal analyses share the same experimental data. A 2020 erratum corrects both color-scale axes in Figure 2 of the prototype paper: they begin at zero, not one. The individual contributor list for the later paper is incomplete; matching initials alone do not establish identity.
