Rapid solution of the cryo-EM reconstruction problem by frequency marching
Alex Barnett, Leslie Greengard, Andras Pataki +1
Determining the three-dimensional structure of proteins and protein complexes at atomic resolution is a fundamental task in structural biology. Over the last decade, remarkable pro…
A fast, high-order solver for the Grad-Shafranov equation
Andras Pataki, Antoine J. Cerfon, Jeffrey P. Freidberg +2
We present a new fast solver to calculate fixed-boundary plasma equilibria in toroidally axisymmetric geometries. By combining conformal mapping with Fourier and integral equation…
On the efficient representation of the half-space impedance Green's function for the Helmholtz equation
Michael O'Neil, Leslie Greengard, Andras Pataki
A classical problem in acoustic (and electromagnetic) scattering concerns the evaluation of the Green's function for the Helmholtz equation subject to impedance boundary conditions…
Fast elliptic solvers in cylindrical coordinates and the Coulomb collision operator
Andras Pataki, Leslie Greengard
In this paper, we describe a new class of fast solvers for separable elliptic partial differential equations in cylindrical coordinates with free-space radiation conditio…
