High-Frequency Gravitational Wave Constraints from Precision Spectroscopy
Dmitry Budker, Valerie Domcke, Joachim Kopp +1
Gravitational waves affect the propagation of electromagnetic waves in laser cavities, modulating the frequency of emitted photons. We use this effect to search for high-frequency…

High-Frequency Gravitational Waves from Phase Transitions in Nascent Neutron Stars
Katarina Bleau, Joachim Kopp, Jiheon Lee +1
Tentative evidence suggests that the cores of massive neutron stars consist of deconfined quark matter. We argue that the formation of such a quark matter core during a galactic su…
