Ab initio density response and local field factor of warm dense hydrogen

open access: yesMatter and Radiation at Extremes
We present quasi-exact ab initio path integral Monte Carlo (PIMC) results for the partial static density responses and local field factors of hydrogen in the warm dense matter regime, from solid density conditions to the strongly compressed case.

Analytical Solutions of Symmetric Isotropic Spin Clusters Using Spin and Point Group Projectors

open access: yesMagnetism
Spin models like the Heisenberg Hamiltonian effectively describe the interactions of open-shell transition-metal ions on a lattice and can account for various properties of magnetic solids and molecules.

Understanding Understanding and Non-Understanding: The Problems and Possibilities

open access: yes, 2021
Life is not limited to the coordinated functioning of millions of cells that make an individual or to one’s struggle for survival. It’s also about our pursuit to reach the Ultimate, or the Absolute in Hegel’s terms. In his search for the absolute, he too yearned for someone who would truly understand him.
