abstract
This Letter reports new results from the HAYSTAC experiment's search for dark matter axions in our galactic halo. It represents the widest search to date that utilizes squeezing to realize sub-quantum limited noise. The new results cover 1.71 $\mu$eV of newly scanned parameter space in the mass ranges 17.28-18.44 $\mu$eV and 18.71-19.46 $\mu$eV. No statistically significant evidence of an axion signal was observed, excluding couplings $|g_\gamma|\geq$ 2.75$\times$$|g_{\gamma}^{\text{KSVZ}}|$ and $|g_\gamma|\geq$ 2.96$\times$$|g_{\gamma}^{\text{KSVZ}}|$ at the 90$\%$ confidence level over the respective region. By combining this data with previously published results using HAYSTAC's squeezed state receiver, a total of 2.27 $\mu$eV of parameter space has now been scanned between 16.96-19.46 $\mu$eV, excluding $|g_\gamma|\geq$ 2.86$\times$$|g_{\gamma}^{\text{KSVZ}}|$ at the 90$\%$ confidence level. These results demonstrate the squeezed state receiver's ability to probe axion models over a significant mass range while achieving a scan rate enhancement relative to a quantum-limited experiment.

Suppressed Quantum Effects of Weakly Coupled Waves
Nonclassical (quantum) signatures of weakly coupled waves are suppressed by an extra power of the tiny conversion efficiency η (~10^-21 for axions, ~10^-33 for gravitons), so experiments cannot establish the quantizat...

Abelian-Higgs vortices in the oscillating axion background
Axion oscillations can resonantly amplify electric fields inside Abelian-Higgs vortex cores and induce attractive or repulsive forces between vortices, even in the BPS limit.

Axiverse Lampposts
In a hierarchical multi-axion theory with random couplings, axion field ranges shrink with 1/sqrt(N), generic axion–SM couplings are suppressed, but the QCD axion's coupling is unsuppressed.

Probing the axion-electron coupling at cavity experiments
Cavity walls radiate microwave photons when axion dark matter generates a chiral magnetic current at the conductor surface, turning existing haloscope data into a bound on the axion-electron coupling g_ae ≲ 10^-5.
