Nelson-Barr ultralight dark matter
We show that, in the Nelson-Barr solution to the strong CP-problem, a naturally light scalar
can arise. It gives rise to a completely new phenomenology beyond that of the celebrated …

Detection of bosenovae with quantum sensors on Earth and in space
In a broad class of theories, the accumulation of ultralight dark matter (ULDM) with particles
of mass 10-22 eV< m ϕ< 1 eV leads to the formation of long-lived bound states known as …
