EHPRG

Welcome to the official website of the European High Pressure Research Group (EHPRG).

EHPRG is non-profitable academic association established in 1963 which is devoted to science and technology of matter under high pressure. It organizes an annual meeting which brings together hundreds of scientists of various fields, mainly physics, chemistry, Earth and planetary sciences, bio- and food science and technology.

The reasonable size of the group, low conference fees, and a friendly relationship between the attendants have made EHPRG meetings a major event in the European high-pressure community for more than half a century.

The potential for bridgmanite megacrysts to drive magma ocean segregation
by Jie Deng


Nature, Published online: 21 January 2026; doi:10.1038/s41586-025-10063-5

Large-scale molecular dynamics simulations show that the crystal–melt interfacial energies of MgSiO3 bridgmanite increase substantially with pressure, potentially forming unusually large bridgmanite crystals and suggesting a new physical mechanism driving magma ocean segregation.

Colloquium: Room temperature superconductivity: The roles of theory and materials design
by Warren E. Pickett
Author(s): Warren E. Pickett


Superconductivity, discovered in 1911 and first theoretically understood in 1957, remains a fascinating phenomenon for reasons both fundamental and applied. Reliably calculating the critical temperature of a given material, and even more so predicting it, turned out to be a considerable challenge. This Colloquium explains how theoretical developments have led to increasingly reliable predictions that have culminated in the discovery of the hydride materials that display superconductivity under high pressure at temperatures just shy of room temperature.

Enhancement of antiferromagnetic spin fluctuations in ${\mathrm{UTe}}_{2}$ under pressure revealed by $^{125}\mathrm{Te}$ NMR
by Devi Vijayan Ambika, Qing-Ping Ding, Corey E. Frank, Sheng Ran, Nicholas P. Butch, and Yuji Furukawa
Author(s): Devi Vijayan Ambika, Qing-Ping Ding, Corey E. Frank, Sheng Ran, Nicholas P. Butch, and Yuji Furukawa


The authors investigate here the evolution of magnetic fluctuations under pressure in the spin-triplet superconductor candidate UTe2, which exhibits multiple superconducting phases. These are SC1, in which the critical temperature (Tc) decreases with increasing pressure, and SC2, where Tc increases. Using 125Te NMR measurements, the authors reveal the coexistence of antiferromagnetic and ferromagnetic fluctuations, where the antiferromagnetic fluctuations are enhanced as pressure increases. This suggests a significant role for antiferromagnetic fluctuations in stabilizing the SC2 phase, while rendering the SC1 phase less favorable.
