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 Joint 28th AIRAPT and 60th EHPRG International Conference on High Pressure Science and Technology (AIRAPT-2023), originally scheduled for July 2021, will be held in Edinburgh, UK, from July 23-28, 2023.
The Conference will be held at the Edinburgh International Conference Centre (EICC) and it will be a face-to-face conference only.
Immediately prior to AIRAPT/EHPRG, from the 19th to 23rd of July 2023, a Summer School will take place, also based in Edinburgh, with accommodation provided in University Halls of Residence. The School is aimed at young researchers, and experimentalists wanting a grounding in theory and vice versa.
For more information, please visit the official webpage of AIRAPT-23.

 


The 59th European High Pressure Research Group Meeting on High Pressure Science and Technology (EHPRG2022) took place in Uppsala, Sweden, from 5th to 8th September 2022.
Meeting sessions were held virtually. The 59th EHPRG intended to be a large scope conference, in line with the rapid increase of high pressure activities in all areas of Physics, Chemistry, Food Science, Geosciences, Material Research, and Biosciences.

    In this work, the high-pressure and high-temperature (HPHT) method was applied to obtain crystalline tin disulfide (${\mathrm{SnS}}_{2}$). The synthesis was performed in a sulfur-tin-carbon growth system by placing the reaction mixture of sulfur and tin in a graphite capsule. The synthesized ${\math…

    Charge density wave and superconductivity in the kagome metal ${\mathrm{CsV}}_{3}{\mathrm{Sb}}_{5}$ around a pressure-induced quantum critical point
    by Chongze Wang, Shuyuan Liu, Hyunsoo Jeon, Yu Jia, and Jun-Hyung Cho
    Author(s): Chongze Wang, Shuyuan Liu, Hyunsoo Jeon, Yu Jia, and Jun-Hyung Cho

    Using first-principles density-functional theory calculations, we investigate the pressure-induced quantum phase transition (QPT) from the charge density wave (CDW) to the pristine phase in the layered kagome metal ${\mathrm{CsV}}_{3}{\mathrm{Sb}}_{5}$ consisting of three-atom-thick $\mathrm{Sb}\tex…

    Author(s): A. Tröster, C. Verdi, C. Dellago, I. Rychetsky, G. Kresse, and W. Schranz

    We investigate the properties of hard antiphase boundaries in ${\mathrm{SrTiO}}_{3}$ using machine-learned force fields. In contrast to earlier findings based on standard ab initio methods, for all pressures up to $120\phantom{\rule{0.16em}{0ex}}\mathrm{kbar}$ the observed domain wall pattern mainta…

    Here we report the discovery of pressure-induced superconductivity in quasi-one-dimensional ${\mathrm{Ta}}_{2}{\mathrm{PdSe}}_{6}$, through a combination of electrical transport, synchrotron x-ray diffraction, and theoretical calculations. Our transport measurements show that the superconductivity a…

    The ${\mathrm{Cr}}^{4+}$ oxidation state with two electrons in the $\mathrm{Cr}\phantom{\rule{0.28em}{0ex}}3d$ shell is not often observed in perovskite-type oxides, as high pressures and temperatures are generally required to stabilize the octahedral coordination. Herein, we present a comparative s…
