New Method to Precisely Measure Strong Interaction Between Nucleons

Within the atomic nuclei, the positively charged protons should, in fact, repel each other. However, even heavy nuclei with numerous neutrons and protons stay bound together. This is feasible due to the so-called strong interaction.

A Technique to Sift Out the Universe’s First Gravitational Waves

In the moments immediately following the Big Bang, the very first gravitational waves rang out. The product of quantum fluctuations in the new soup of primordial matter, these earliest ripples through the fabric of space-time were quickly amplified by inflationary processes that drove the universe to explosively expand.

Reducing Background Noise to Make Quantum Gravity Experiment More Manageable

Is gravity a quantum phenomenon- That has been one of the big outstanding questions in physics for decades. Together with colleagues from the UK, Anupam Mazumdar, a physicist from the University of Groningen, proposed an experiment that could settle the issue.
