Dark Matter-Induced Stellar Oscillations in the de Broglie Regime
Qiuyue Liang, Jeremy Sakstein
We investigate stellar oscillations driven by the time-dependent gravitational potential of ultralight dark matter (ULDM) in the de Broglie regime. The response is controlled by th…
Detecting Parity-Violating Gravitational Wave Backgrounds with Pulsar Polarization Arrays
Qiuyue Liang, Kimihiro Nomura, Hidetoshi Omiya
Pulsar timing arrays probe isotropic stochastic gravitational wave (GW) backgrounds in the nanohertz band but are insensitive to its parity-violating component. Motivated by recent…
First astrometric constraints on parity-violation in the gravitational wave background
Santiago Jaraba, Sachiko Kuroyanagi, Qiuyue Liang +2
Astrometry, the precise measurement of stellar positions and velocities, offers a promising approach to probing the low-frequency stochastic gravitational wave background (SGWB). N…
Semantics at an Angle: When Cosine Similarity Works Until It Doesn't
Kisung You
Cosine similarity is a standard comparison rule for learned representations in information retrieval, natural language processing, computer vision, and multimodal learning. Its pop…
Relativistic Fractons and their Dust
Qiuyue Liang, Tom Melia
We define a relativistic version of the global symmetries responsible for the restricted mobility of fracton quasiparticles. The theories have a symmetry current that is proportion…
Simulations of Shapiro, Gravitational, and Doppler time delays in pulsar networks for ultralight dark matter
Andrew Eberhardt, Qiuyue Liang, Elisa G. M. Ferreira
The study of ultralight dark matter helps to constrain the lower bound of the mass in minimally coupled dark matter models. The granular structure of ultralight dark matter density…
