The Outcome of Collisions between Gaseous Clumps formed by Disk Instability

Yoav Matzkevich, Christian Reinhardt, Thomas Meier +2

The disk instability model is a promising pathway for giant planet formation in various conditions. At the moment, population synthesis models are used to investigate the outcomes…

High-Pressure Synthesis of Seven Lanthanum Hydrides with a Significant Variability of Hydrogen Content

Dominique Laniel, Florian Trybel, Bjoern Winkler +12

The lanthanum-hydrogen system has attracted significant attention following the report of superconductivity in LaH10 at near-ambient temperatures and high pressures. Here, we prese…

NMR close to Mega-Bar Pressures

Thomas Meier, Saiana Khandarkhaeva, Sylvain Petitgirard +4

The past 15 years have seen an astonishing increase in Nuclear Magnetic Resonance (NMR) sensitivity and accessible pressure range in high-pressure NMR experiments, owing to a serie…

A scaling relation for core heating by giant impacts and implications for dynamo onset

You Zhou, Peter E. Driscoll, Mingming Zhang +2

Accretional heating of Earth's interior during formation is pivotal to its subsequent thermal and chemical evolution. In particular, impact heating of Earth's core is expected, but…

On the origin of Jupiter's fuzzy core: constraints from N-body, impact and evolution simulations

Thomas Meier, Christian Reinhardt, Sho Shibata +3

It has been suggested that Jupiter's fuzzy core could be a result of a giant impact. Here, we investigate the expected impact conditions from N-body simulations. We then use state-…

Observation of robust spin-phonon coupling and indication of hidden structural transition in the spin-driven ferroelectrics Mn4B_2O_9 (B= Nb, Ta)

Rajesh Jana, Alka Garg, Rekha Rao +1

We report detailed Raman spectroscopic and magnetic susceptibility studies on the spin-driven ferroelectric compounds Mn4Nb2O9 (MNO) and Mn4Ta2O9 (MTO). Both systems exhibit strong…
