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.

Selection of high-pressure related titles from top scientific journals.

Agonist antibody to guanylate cyclase receptor NPR1 regulates vascular tone
by Michael E. Dunn


Nature, Published online: 11 September 2024; doi:10.1038/s41586-024-07903-1

Durable agonism of NPR1 achieved with a novel investigational monoclonal antibody could mirror the positive hemodynamic changes in blood pressure and heart failure identified in humans with lifelong exposure to NPR1 coding variants.

Orientational Disorder Drives Site Disorder in Plastic Ammonia Hemihydrate
by Niccolò Avallone, Simon Huppert, Philippe Depondt, Leon Andriambariarijaona, Frédéric Datchi, Sandra Ninet, Thomas Plé, Riccardo Spezia, and Fabio Finocchi
Author(s): Niccolò Avallone, Simon Huppert, Philippe Depondt, Leon Andriambariarijaona, Frédéric Datchi, Sandra Ninet, Thomas Plé, Riccardo Spezia, and Fabio Finocchi


In the 2–10 GPa pressure range, ammonia hemihydrate ${\mathrm{H}}_{2}\mathrm{O}:({\mathrm{NH}}_{3}{)}_{2}$ (AHH) is a molecular solid in which intermolecular interactions are ruled by distinct types of hydrogen bonds. Upon heating, the low-temperature ordered $P{2}_{1}/c$ crystal (AHH-II) transits t…

Quenched Pair Breaking by Interlayer Correlations as a Key to Superconductivity in ${\mathrm{La}}_{3}{\mathrm{Ni}}_{2}{\mathrm{O}}_{7}$
by Siheon Ryee, Niklas Witt, and Tim O. Wehling
Author(s): Siheon Ryee, Niklas Witt, and Tim O. Wehling


The recent discovery of superconductivity in ${\mathrm{La}}_{3}{\mathrm{Ni}}_{2}{\mathrm{O}}_{7}$ with ${T}_{\mathrm{c}}≃80\text{ }\text{ }\mathrm{K}$ under high pressure opens up a new route to high-${T}_{\mathrm{c}}$ superconductivity. This material realizes a bilayer square lattice model featurin…

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.

${T}_{\mathrm{c}}$ and resistivity variation induced by external bending strain in flexible film of strain-sensitive ${(\mathrm{La},\mathrm{Sr})}_{2}\mathrm{Cu}{\mathrm{O}}_{4}$
by Tomoya Horide, Tomoaki Maekawa, Tatsuro Aikawa, Takanori Kitamura, and Kazuma Nakamura
Author(s): Tomoya Horide, Tomoaki Maekawa, Tatsuro Aikawa, Takanori Kitamura, and Kazuma Nakamura


Strain in materials changes their electronic structure, and the strain response realizes rich material properties and devices. Superconductivity under hydrostatic pressure and epitaxial strain suggests significant response to an external variable strain in a single sample, but this has not yet been …

We investigate the crystal and electronic structures as well as magnetic properties of ilmenite-type $\mathrm{NiV}{\mathrm{O}}_{3}$, which has attracted research interest as an $S$ = 1 honeycomb lattice magnet. Ilmenite-type $\mathrm{NiV}{\mathrm{O}}_{3}$ samples were synthesized under high-pressure…

Strong correlation between ionic bonding strength and superconductivity in compressed hydrides
by Xing Li, Zixuan Guo, Yansun Yao, Xiaohua Zhang, Shicong Ding, and Guochun Yang
Author(s): Xing Li, Zixuan Guo, Yansun Yao, Xiaohua Zhang, Shicong Ding, and Guochun Yang


Understanding the superconductivity in relation to chemical bonding is essential for the development of superconductors. We propose that pressure-reduced ionic bonding strength is beneficial for improving superconductivity in hydrides (negative correlation between bonding strength and critical tempe…

Author(s): Junyi Miao, Shi He, Kaihua He, Kewei Ding, Wei Dai, and Cheng Lu


Ammonia is the most stable compound of nitrogen and hydrogen at ambient pressure. However, the chemical reaction of nitrogen and hydrogen is more complex and difficult to explore at high pressures. Here, we have performed extensively structural searches of ammonia-hydrogen compounds based on particl…

Author(s): Shingo Araki, Kaisei Iwamoto, Kazuto Akiba, Tatsuo C. Kobayashi, Koji Munakata, Koji Kaneko, and Toyotaka Osakabe


The $α\text{−}\mathrm{Mn}$ phase exhibits a large anomalous Hall effect (AHE) in its pressure-induced weak ferromagnetic (WFM) state, despite its relatively small spontaneous magnetization of $∼0.02\phantom{\rule{0.222222em}{0ex}}{μ}_{\mathrm{B}}/\mathrm{Mn}$.

Single-crystalline FeSi samples with a conducting surface state were studied under high pressure and magnetic field by means of electrical resistance measurements to explore how the bulk semiconducting state and the surface state are tuned by the application of pressure. We found that the energy gap…
