Re-using model results to determine materials properties: connector theory approach
Marco Vanzini, Ayoub Aouina, Martin Panholzer +2
Computational materials design often profits from the fact that some complicated contributions are not calculated for the real material, but replaced by results of models. We turn…
Optimized correlations inspired by perturbation theory
Martin Panholzer, Raphael Hobbiger, Helga Böhm
We study the accuracy of analytical wave function based many-body methods derived by energy minimization of a Jastrow-Feenberg ansatz for electrons (`Fermi hypernetted chain / Eule…
Dynamic Many-Body Theory. II. Dynamics of Strongly Correlated Fermi Fluids
H. M. Böhm, R. Holler, E. Krotscheck +1
We develop a systematic theory of multi-particle excitations in strongly interacting Fermi systems. Our work is the generalization of the time-honored work by Jackson, Feenberg, an…
Theoretical analysis of neutron and X-ray scattering data on He-3
Eckhard Krotscheck, Martin Panholzer
X-ray scattering experiments on bulk liquid He-3 have indicated the possibility of the existence of a sharp collective mode at large momentum transfers. We address this issue withi…
Pair Excitations and Vertex Corrections in Fermi Fluids
Helga M. Böhm, Eckhard Krotscheck, Martin Panholzer
Based on an equations--of--motion approach for time--dependent pair correlations in strongly interacting Fermi liquids, we have developed a theory for describing the excitation spe…
