Analytical methods for dynamic simulation of non-penetrating rigid bodies
A method for analytically calculating the forces between systems of rigid bodies in resting (non-colliding) contact is presented. The systems of bodies may either be in motion or ...

Dielectric anisotropy in the GW space-time method
Excited-state calculations, notably for quasiparticle band structures, are nowadays routinely performed within the GW approximation for the electronic self-energy. Nevertheless, c...
