Differential torsion sensor for direct detection of ultralight vector dark matter

Ling Sun, Bram J. J. Slagmolen, Jiayi Qin

Ultralight bosons with masses in the range from $\sim 10^{-22}$ eV/$c^2$ to $\sim 1$ eV/$c^2$, are well-motivated, wave-like dark matter candidates. Particles on the lower-mass end…
