Searching for dark matter with the Th-229 nuclear lineshape from laser spectroscopy
Elina Fuchs, Fiona Kirk, Eric Madge +5
The recent laser excitation of the low-lying Th-229 isomer transition is starting a revolution in ultralight dark matter searches. The enhanced sensitivity of this transition to th…
Nelson-Barr ultralight dark matter
Michael Dine, Gilad Perez, Wolfram Ratzinger +1
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 celebrate…
A Coordinate-Independent Formalism for Detecting High-Frequency Gravitational Waves
Wolfram Ratzinger, Sebastian Schenk, Pedro Schwaller
In an external electric or magnetic field, a gravitational wave (GW) may be converted into electromagnetic radiation. We present a coordinate-invariant framework to describe the GW…
