The peak heat flux conjecture for the first Dirichlet eigenmode of convex planar domains
Zijian Wang, Jeremy G. Hoskins, Manas Rachh +1
In this paper, we study the scale-invariant quantity \[\mathcal{G}(Ω)=\frac{\|\partial_n u_1\|_{L^\infty(\partialΩ)}}{λ_1},\]where is the first -normalized Dirichlet Lap…
Self-reorganization and Information Transfer in Massive Schools of Fish
Haotian Hang, Chenchen Huang, Alex Barnett +1
The remarkable cohesion and coordination observed in moving animal groups and their collective responsiveness to threats are thought to be mediated by scale-free correlations, wher…
A fully adaptive, high-order, fast Poisson solver for complex two-dimensional geometries
Daniel Fortunato, David B. Stein, Alex H. Barnett
We present a new framework for the fast solution of inhomogeneous elliptic boundary value problems in domains with smooth boundaries. High-order solvers based on adaptive box codes…
nifty-ls: Fast and Accurate Lomb-Scargle Periodograms Using a Non-Uniform FFT
Lehman H. Garrison, Dan Foreman-Mackey, Yu-hsuan Shih +1
We present nifty-ls, a software package for fast and accurate evaluation of the Lomb-Scargle periodogram. nifty-ls leverages the fact that Lomb-Scargle can be computed using a non-…
High-order and adaptive optical conductivity calculations using Wannier interpolation
Lorenzo Van Muñoz, Jason Kaye, Alex Barnett +1
We present an automatic, high-order accurate, and adaptive Brillouin zone integration algorithm for the calculation of the optical conductivity with a non-zero but small broadening…
Superfast direct inversion of the nonuniform discrete Fourier transform via hierarchically semi-separable least squares
Heather Wilber, Ethan N. Epperly, Alex H. Barnett
A direct solver is introduced for solving overdetermined linear systems involving nonuniform discrete Fourier transform matrices. Such matrices can be transformed into a Cauchy-lik…
Trapped acoustic waves and raindrops: high-order accurate integral equation method for localized excitation of a periodic staircase
Fruzsina J. Agocs, Alex H. Barnett
We present a high-order boundary integral equation (BIE) method for the frequency-domain acoustic scattering of a point source by a singly-periodic, infinite, corrugated boundary.…
