Fourier Transform-Based Computation of Two-Electron Four-Center Coulomb Repulsion Integrals
William Chen, Lior Silberman, Ury Segal +1
We present a Fourier-based method for evaluating two-electron four-center Coulomb repulsion integrals over Slater-type orbitals. Spherical Fourier-Bessel coefficients of the convol…

Preconditioning for Diffuse Interface Tumor Growth Models
Jessica Bosch, Pelin Çiloğlu, Chen Greif +1
Computational models of tumor growth form a contemporary area of study. Diffuse interface models have been proposed as an important tool for cancer modeling. In this work, we consi…
