Recent progress in high-power laser technology and the advent of X-ray free electron lasers have energetically advanced our understanding of matter in extreme environments. Materials dynamically compressed by high-power laser irradiation, which reach ultra-high pressure and temperature states or warm dense matter states, are closely related not only to plasma physics and material science but also to earth and planetary science and inertial confinement fusion researches. Since such materials are highly complex systems, they are interdisciplinary research interests where both experimental and computational contributions are essential. In the scientific research area, we recognize that it is beneficial to hold a conference to promote international and interdisciplinary collaboration and overview the current status and prospects of the related fields. Thus, we propose to hold an international conference at the annual HEDS meeting with a topical focus on "Matter in Extreme Conditions". The conference aims to discuss a definite theme with distinguished overseas scientists with experiences in high-pressure science, shock physics, materials science, earth and planetary science, first-principles calculations, high-power lasers, and X-ray free electron lasers, increasing the number of foremost participants in related fields.

INTERNATIONAL CONFERENCE ON HIGH ENERGY DENSITY SCIENCES 2022 (HEDS2022) is organized to share recent advances in science and technology on the matter under extreme high-energy-density conditions. The conference will be held on April 19- 21, 2022, both online and in-person, with the sponsorship of the Laser Society of Japan, and Institute of Laser Laboratory, Osaka University.
