What's for Lunch? A systematic ordering of foods in the Soup-Salad-Sandwich phase space
Madelyn Leembruggen, Caroline Martin
The statistical physics of phase transitions has been hugely successful at describing numerous natural, physical, and technological phenomena, and now a rigorous examination of the…
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…
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…
Stability of Condensed Fuzzy Dark Matter Halos
Joshua Eby, Madelyn Leembruggen, Peter Suranyi +1
Stability properties of gravitationally bound condensates composed of ultralight axionic Fuzzy Dark Matter (FDM) are studied. Previous work has shown that astrophysical collisions…
