EHPRG: The European High Pressure Research Group

Welcome

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 62nd EHPRG Meeting will take place in Manchester, UK, at the Lowry, in the period August 31-September 5, 2025.
The conference will be chaired by John Proctor, Salford University, UK.
For more information, please visit the official webpage of EHPRG-62 (to appear).

Immediate past EHPRG Meetings

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.
For more information, please visit the official webpage of EHPRG-61.

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.

Colloquium: Room temperature superconductivity: The roles of theory and materials design

by 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.

Interplay of altermagnetism and pressure in hexagonal and orthorhombic MnTe

by Nayana Devaraj, Anumita Bose, and Awadhesh Narayan

Alternative magnetic materials, or “altermagnets,” characterized by their unconventional nonrelativistic, momentum-dependent spin-split states, represent a cutting-edge advancement in the field of collinear magnetism, offering promising avenues for spintronic applications. Among these materials, hex…

Republished: Colossal density-driven resistance response in the negative charge transfer insulator ${\mathrm{MnS}}_{2}$

by Jasmine K. Hinton, Dylan Durkee, Melanie White, Nathan Dasenbrock-Gammon, G. Alexander Smith, Elliot Snider, Dean Smith, Christian Childs, Keith V. Lawler, and Ashkan Salamat

The Mn chalcogenides show a remarkable variation in structural and physical properties with density. In ${\mathrm{MnS}}_{\text{2}}$ we observe a pronounced difference with the effects of varying hydrostaticity with pressure inducing a structural transition at 300 K. Within the pyrite phase, a coloss…

Phonon-mediated superconductivity in the transition metal trioxides $X{\mathrm{O}}_{3} (X=\mathrm{Ru},\mathrm{Re},\mathrm{Os},\mathrm{Ir},\mathrm{Pt})$ under pressure

by Aiqin Yang, Xiangru Tao, Yundi Quan, and Peng Zhang

A recent experiment by P. F. Shan et al. (arXiv:2304.09011) found that rhenium trioxide ${\mathrm{ReO}}_{3}$, a simple metal at ambient pressure, becomes superconducting with a transition temperature as high as 17 K at 30 GPa. In this paper, we analyze the electron-phonon origin of superconductivity…

Crystal structure prediction of lithium-beryllium alloys under pressure with distinctive electronic and dynamic behaviors

by Zhongwei Zhang, Qing Lu, Chi Ding, Tianheng Huang, Yijie Zhu, Yu Han, Junjie Wang, Xiaomeng Wang, and Jian Sun

Using machine learning–assisted crystal structure search and first-principles calculations, we have unveiled two hitherto undiscovered thermodynamically stable stoichiometries, namely, Cmmm $\mathrm{Li}{\mathrm{Be}}_{5}$ and $R\overline{3}m\phantom{\rule{4pt}{0ex}}\mathrm{Li}{\mathrm{Be}}_{6}$, alon…

Role of pressure-induced stacking faults on the magnetic properties of gadolinium

by Rafael Martinho Vieira, Olle Eriksson, Alena Vishina, Torbjörn Björkman, Ondřej Šipr, Patrik Thunström, and Heike C. Herper

Experimental data show that under pressure, Gd goes through a series of structural transitions $\mathrm{hcp}→\mathrm{Sm}$-type (close-packed rhombohedral) $→\mathrm{dhcp}$ that is accompanied by a gradual decrease of the Curie temperature and magnetization till the collapse of a finite magnetization…

Unconventional pressure-dependent interorbital and interlayer doping in superconducting nickelates

by Y. N. Huang and David J. Singh

The discovery of nickelate superconductivity provided the first example of a non-copper-based material with superconductivity strongly analogous to the cuprates. However, recent findings raise questions and inconsistencies around the electron counts and doping phase diagrams. We show using supercond…

Exploring ${\mathrm{NH}}_{x}\text{−}\mathrm{Xe}$ compounds with high hydrogen storage capacity and stability at high pressure

by Min Zou, Wenwen Cui, Jian Hao, Jingming Shi, and Yinwei Li

Recent studies have demonstrated that the chemical reactivity of noble gas elements, such as Xe and He, increases significantly under high pressure, leading to the discovery of many unconventional compounds that are unstable under ambient conditions. In this paper, we propose three different and ene…
