Is the Conventional Picture of Coherence Time Complete? Dark Matter Recoherence
Chaitanya Paranjape, Gilad Perez, Wolfram Ratzinger +1
The local solar gravitational potential forms a basin for ultralight dark matter (ULDM), with discrete energy levels. Even if barely populated, it introduces a new characteristic t…

Lorentz violating backgrounds from quadratic, shift-symmetric, ultralight dark matter
Minyuan Jiang, Benjamin D. Pecjak, Gilad Perez +1
We consider an effective theory for a shift-symmetric, quadratically-coupled, ultralight spin-0 field. The leading CP-conserving interactions with Standard Model fields in the effe…
