Diffeomorphic density registration
Martin Bauer, Sarang Joshi, Klas Modin
In this book chapter we study the Riemannian Geometry of the density registration problem: Given two densities (not necessarily probability densities) defined on a smooth finite di…

General method for atomistic spin-lattice dynamics with first principles accuracy
Johan Hellsvik, Danny Thonig, Klas Modin +5
We present a computationally efficient general first-principles based method for spin-lattice simulations for solids. Our method is based on a combination of atomistic spin dynamic…

A Multiscale Theory for Image Registration and Nonlinear Inverse Problems
Klas Modin, Adrian Nachman, Luca Rondi
In an influential paper, Tadmor, Nezzar and Vese (Multiscale Model. Simul. (2004)) introduced a hierarchical decomposition of an image as a sum of constituents of different scales.…
