DAMA/LIBRA and dark matter: decisive tension or contrived cancellation
Giorgio Busoni, Jonathan M. Cornell, Will Handley +6
The ANAIS-112 and COSINE-100 experiments were constructed to test the long-observed dark matter-like annual modulation signal reported by DAMA. While they have reported null result…
Probing Bosonic Overdensities with Optomechanical Sensing
Katherine Slattery, Joshua Eby, Lauren Street +1
Previous work has shown that optomechanical force sensing can be used for efficient detection of ultralight (sub-eV) dark matter candidates. We propose to extend the reach of this…
WKB approximation to boson dark matter
Lauren Street, Peter Suranyi, L. C. R. Wijewardhana
Galactic dark matter halos may be composed of ultralight axions (ULAs) ( eV) with wave functions that satisfy nonlinear Schrödinger-Poisson equations (SPA). We find…
Testing multiflavored ULDM models with SPARC
Lauren Street, Nickolay Y. Gnedin, L. C. R. Wijewardhana
We perform maximum likelihood estimates (MLEs) for single and double flavor ultralight dark matter (ULDM) models using the Spitzer Photometry and Accurate Rotation Curves (SPARC) d…
Interacting dark energy axions in light of the Hubble tension
Ennis Mawas, Lauren Street, Richard Gass +1
A current problem within the ΛCDM framework is the tension between late and early time measurements of the Hubble parameter today, H0. We entertain the possibility that dark energy…
RG Flow and Symmetry Breaking in a Weakly Coupled Model
Thomas Appelquist, Lauren Street, L. C. R. Wijewardhana
We explore a weakly coupled gauge theory, examining its fixed-point structure and the transition from infrared conformality to spontaneous symmetry breaking. Following…
Using atomic clocks to detect local dark matter halos
Chris Kouvaris, Eleftherios Papantonopoulos, Lauren Street +1
It is possible that bosonic dark matter forms halos around the Sun or the Earth. We discuss the possibility of probing such halos with atomic clocks. Focusing on either a Higgs por…
Density profile of multi-state fuzzy dark matter
Lauren Street, Peter Suranyi, L. C. R. Wijewardhana
Equations of motion for excited states of weakly self-interacting bosons forming fuzzy dark matter are solved using the WKB approximation. The contribution of self-interactions are…
Global View of Axion Stars with (Nearly) Planck-Scale Decay Constants
Joshua Eby, Lauren Street, Peter Suranyi +1
We show that axion stars formed from axions with nearly Planck-scale decay constants are unstable to decay, and are unlikely to have phenomenological consequences. More general…
Galactic Condensates composed of Multiple Axion Species
Joshua Eby, Madelyn Leembruggen, Lauren Street +2
Ultralight scalar dark matter has been proposed to constitute a component of dark matter, though the minimal scenarios have increasingly become constrained. In this work, we analyz…
Probing Bosonic Stars with Atomic Clocks
Chris Kouvaris, Eleftherios Papantonopoulos, Lauren Street +1
Dark Matter could potentially manifest itself in the form of asymmetric dark stars. In this paper we entertain the possibility of probing such asymmetric bosonic dark matter stars…
Global view of QCD axion stars
Joshua Eby, Madelyn Leembruggen, Lauren Street +2
Taking a comprehensive view, including a full range of boundary conditions, we reexamine QCD axion star solutions based on the relativistic Klein-Gordon equation (using the Ruffini…
On Approximation Methods in the Study of Boson Stars
Joshua Eby, Madelyn Leembruggen, Lauren Street +2
We analyze the accuracy of the variational method in computing physical quantities relevant for gravitationally bound Bose-Einstein condensates. Using a variety of variational ansä…
