One-DAY UK-APP Meeting Morning II
- Jamie McDonald (University of Manchester)
Many well theoretically motivated models of ultralight dark matter are expected to give rise to feeble oscillatory forces on macroscopic objects. Optically trapped sensors have high force sensitivies but have remained relatively unexplored in this context. In this talk we propose a new, tunable, optically trapped sensor specifically designed to detect such forces. Our design features a...
In a broad class of theories, the accumulation of ultralight dark matter (ULDM) with particles of mass $10^{-22}~\textrm{eV} < m_{\phi} < 1~\textrm{eV}$ leads to the formation of long-lived bound states known as boson stars. When the ULDM exhibits self-interactions, prodigious bursts of energy carried by relativistic bosons are released from collapsing boson stars in bosenova explosions. We...
