A Fast Volume Integral Equation Solver with Linear Basis Functions for the Accurate Computation of Electromagnetic Fields in MRI
Ioannis P. Georgakis, Ilias I. Giannakopoulos, Mikhail S. Litsarev +1
A stable volume integral equation (VIE) solver based on polarization/magnetization currents is presented, for the accurate and efficient computation of the electromagnetic scatteri…
Memory footprint reduction for the FFT-based volume integral equation method via tensor decompositions
Ilias I. Giannakopoulos, Mikhail S. Litsarev, Athanasios G. Polimeridis
We present a method of memory footprint reduction for FFT-based, electromagnetic (EM) volume integral equation (VIE) formulations. The arising Green's function tensors have low mul…
On the Generalization of DIRECTFN for Singular Integrals Over Quadrilateral Patches
Alexandra Tambova, Mikhail Litsarev, Georgy Guryev +1
A set of fully numerical algorithms for evaluating the four-dimensional singular integrals arising from Galerkin surface integral equation methods over conforming quadrilateral mes…
What Lies Beneath the Surface: Topological-Shape Optimization With the Kernel-Independent Fast Multipole Method
Igor Ostanin, Ivan Tsybulin, Mikhail Litsarev +2
The paper presents a new method for shape and topology optimization based on an efficient and scalable boundary integral formulation for elasticity. To optimize topology, our appro…
The valence and spectral properties of rare-earth clusters
L. Peters, I. Di Marco, M. S. Litsarev +5
The rare-earths are known to have intriguing changes of the valence, depending on chemical surrounding or geometry. Here we make predictions from theory that combines density funct…
Fast low-rank approximations of multidimensional integrals in ion-atomic collisions modelling
M. S. Litsarev, I. V. Oseledets
An efficient technique based on low-rank separated approximations is proposed for computation of three-dimensional integrals arising in the energy deposition model that describes i…
A low-rank approach to the computation of path integrals
M. S. Litsarev, I. V. Oseledets
We present a method for solving the reaction-diffusion equation with general potential in free space. It is based on the approximation of the Feynman-Kac formula by a sequence of c…

Correlated electronic structure and chemical bonding of Ce pnictides and gamma-Ce
Mikhail S. Litsarev, Igor Di Marco, Patrik Thunstrom +1
We present calculated spectral properties and lattice parameters for cerium pnictides (CeN, CeP, CeAs, CeSb, CeBi) and gamma-Ce, within the LDA/GGA+DMFT (local density approximatio…
The DEPOSIT computer code: calculations of electron-loss cross sections for complex ions colliding with neutral atoms
Mikhail Litsarev
A description of the DEPOSIT computer code is presented. The code is intended to calculate total and m-fold electron-loss cross sections (m is the number of ionized electrons) and…
