Visualizing differences in nuclear structure
Helium usually has two protons and two neutrons strongly bound to each other, often forming a substructure within the nucleus. A nucleus composed of several such substructures is called a cluster structure. In the standard picture, nuclei are difficu.....»»
High harmonic spectroscopy retrieves electronic structure of high-pressure superconductors
High pressure has revealed surprising physics and created novel states in condensed matter. Exciting examples include near room temperature superconductivity (Tc > 200 K) in high-pressure hydrides such as H3S and LaH10......»»
Improving Arctic greenhouse gas sink and source estimates with field measurements, remote sensing
