EHPRGWelcome
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.
Upcoming EHPRG Meeting
The 63rd EHPRG Meeting will take place in Montpellier, France, in the period August 23-28, 2026.
The conference will be chaired by Julien Haines and Jérôme Rouquette, ICGM, Université de Montpellier, France.
Immediate past EHPRG Meetings
The 62nd EHPRG Meeting took place in Manchester, UK, at the Lowry, in the period August 31-September 5, 2025.
The conference was chaired by John Proctor, Salford University, UK.

The 61st EHPRG Meeting has taken place in Thessaloniki, Greece, at the Porto Palace Hotel, in the period September 1-6, 2024.
The conference has been chaired by John Arvanitidis and Dimitris Christofilos, Aristotle University of Thessaloniki.

The Joint 28th AIRAPT and 60th EHPRG International Conference on High Pressure Science and Technology (AIRAPT-2023) took place in Edinburgh, UK, at the Edinburgh International Conference Centre (EICC), from July 23-28, 2023.
Immediately prior to AIRAPT/EHPRG, from the 19th to 23rd of July 2023, a Summer School had taken place, also based in Edinburgh, with accommodation provided in University Halls of Residence. The School was aimed at young researchers, and experimentalists wanting a grounding in theory and vice versa.
A photo album is available on the AIRAPT website.

Pressure-Induced Polyhedral Reorganization Causes Indirect-to-Direct Band-Gap Transition in Spinel Structure
by Pengfei Shen, Donghao Xu, Zhiguo Xia, and Mingguang Yao
Author(s): Pengfei Shen, Donghao Xu, Zhiguo Xia, and Mingguang Yao
Spinel oxides (${\mathrm{AB}}_{2}{\mathrm{O}}_{4}$) are promising optoelectronic materials due to their structural stability and tunable electronic properties. However, conventional strategies like doping, element substitution, and thermal treatment have achieved limited success in optimizing their …

Flowing Menisci: Coupled Dynamics and Liquid Exchange with Soap Films
by Alexandre Vigna-Brummer, Antoine Monier, Isabelle Cantat, Christophe Brouzet, and Christophe Raufaste
Author(s): Alexandre Vigna-Brummer, Antoine Monier, Isabelle Cantat, Christophe Brouzet, and Christophe Raufaste
Liquid foams exhibit menisci whose lengths range from hundreds of microns in microfoams to several centimeters in macroscopic bubble arrangements. These menisci are known to thin under gravity until reaching a steady thickness profile, where hydrostatic and capillary pressures are balanced. However,…

Neutron diffraction reveals that superconductivity in UTe2 emerges near an incommensurate antiferromagnetic phase under pressure, pointing to antiferromagnetic—rather than ferromagnetic—correlations as a key driving force.

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.

Pressure suppresses the density wave order in kagome metal ${\mathrm{LuNb}}_{6}{\mathrm{Sn}}_{6}$
by William R. Meier, David E. Graf, Brenden R. Ortiz, Shirin Mozaffari, and David Mandrus
Author(s): William R. Meier, David E. Graf, Brenden R. Ortiz, Shirin Mozaffari, and David Mandrus
The density waves that develop in kagome metals ${\mathrm{ScV}}_{6}{\mathrm{Sn}}_{6}$ and ${\mathrm{LuNb}}_{6}{\mathrm{Sn}}_{6}$ at low temperature appear to arise from underfilled atomic columns within a V-Sn or Nb-Sn scaffolding. Compressing this network with applied pressure in ${\mathrm{ScV}}_{6…

by Brenden W. Hamilton and Timothy C. Germann
Author(s): Brenden W. Hamilton and Timothy C. Germann
High-pressure shear band formation is a critical phenomenon in energetic materials because of its ability to form hotspots and influence mechanical strength. Shear banding is known to occur in a variety of these materials, but the governing dynamics of the mechanisms are not well defined for molecul…
