Bendability parameter for twisted ribbons to describe longitudinal wrinkling and delineate the near-threshold regime

Madelyn Leembruggen, Jovana Andrejevic, Arshad Kudrolli +1

We propose a dimensionless bendability parameter, for wrinkling of thin, twisted ribbons with thickness , width , and tensional st…

A computational model of twisted elastic ribbons

Madelyn Leembruggen, Jovana Andrejevic, Arshad Kudrolli +1

We develop an irregular lattice mass-spring-model (MSM) to simulate and study the deformation modes of a thin elastic ribbon as a function of applied end-to-end twist and tension.…

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…

QCD Axion Star Collapse with the Chiral Potential

Joshua Eby, Madelyn Leembruggen, Peter Suranyi +1

In a previous work, we analyzed collapsing axion stars using the low-energy instanton potential, showing that the total energy is always bounded and that collapsing axion stars do…

Collisions of Dark Matter Axion Stars with Astrophysical Sources

Joshua Eby, Madelyn Leembruggen, Joseph Leeney +2

If QCD axions form a large fraction of the total mass of dark matter, then axion stars could be very abundant in galaxies. As a result, collisions with each other, and with other a…

Collapse of Axion Stars

Joshua Eby, Madelyn Leembruggen, Peter Suranyi +1

Axion stars, gravitationally bound states of low-energy axion particles, have a maximum mass allowed by gravitational stability. Weakly bound states obtaining this maximum mass hav…
