$c$ -Birkhoff polytopes

Esther Banaian, Sunita Chepuri, Emily Gunawan +1

In a 2018 paper, Davis and Sagan studied several pattern-avoiding polytopes. They found that a particular pattern-avoiding Birkhoff polytope had the same normalized volume as the o…

$O (k)$ -Equivariant Dimensionality Reduction on Stiefel Manifolds

Andrew Lee, Harlin Lee, Jose A. Perea +2

Many real-world datasets live on high-dimensional Stiefel and Grassmannian manifolds, $V_{k} (R^{N})$ and $G r (k, R^{N})$ respectively, and benefit from projection onto l…

Aligning a Majorana fermion's anapole moment with an external current through photon emission mediated by the fermion's generalized polarizabilities

Kiana Walter, Kobi Hall, David C. Latimer

The sole static electromagnetic property of a spin- $\frac{1}{2}$ Majorana fermion is its anapole moment. Though they cannot couple to single real photons, these particles can inter…

Optimal renormalization of multi-scale systems

Jacob Price, Brek Meuris, Madelyn Shapiro +1

While model order reduction is a promising approach in dealing with multi-scale time-dependent systems that are too large or too expensive to simulate for long times, the resulting…

$Z_{/ p} \times Z_{/ p}$ actions on $S^{n} \times S^{n}$

Jim Fowler, Courtney Thatcher

We determine the homotopy type of quotients of $S^{n} \times S^{n}$ by free actions of $Z_{/ p} \times Z_{/ p}$ where $2 p > n + 3$ . Much like free $Z_{/ p}$ actions, t…

Scattering from a quantum anapole at low energies

Kyle M. Whitcomb, David C. Latimer

In quantum field theory, the photon-fermion vertex can be described in terms of four form factors which encode the static electromagnetic properties of the particle, namely its cha…
