The SECUF series of annual conferences and summer schools was firstly launched in 2022, for promoting academic exchange and collaboration on cutting-edge research in condensed matter physics and material science under synergetic extreme conditions. It is based on a newly accomplished user facility - Synergetic Extreme Condition User Facility (SECUF) which is located in Huairou, Beijing and is now opening to academic and industrial users in China and world-wide. Previously, SECUF-2022 (online), SECUF-2023 (in person) and SECUF-2024 (in person) were successfully organized, with the participation of hundreds of invited speakers and a large audience.

SECUF-2025 consists of two parts. The first part is a Summer School, which delivers tutorial lectures on fundamental knowledges of researches under extreme physical conditions, together with the introduction of the experimental conditions available in SECUF. The second part is a Conference containing two plenary sessions and four parallel sessions, for exchanging newest research progresses under extreme physical conditions.

Plenary Sessions 1&2: Physics under synergetic extreme conditions.

Session 1: Emergent quantum materials and phenomena under high pressures

Session 2: Novel physical properties of materials under extreme conditions

Session 3: Quantum transport in low dimensional materials and quantum devices at ultralow temperatures.
