Group QM@HP

Quantum materials are a special class of materials which can exhibit variety of emergence phenomena with electronic, magnetic, and optical properties arising from quantum mechanical effects at the microscopic or mesoscopic levels. These materials often possess strongly correlated electron behavior, where the cooperative or collective behavior of many-body system gives rise to the emergence phenomena such as superconductivity, magnetism, or topological states. Since the properties of materials can be applied in various fields that includes electronics, energy storage, quantum computing and spintronics, the research field of quantum materials are an active area for exploring the new quantum phenomena, advancing the fundamental understanding of quantum physics and enabling technological advancements. As an effective tuning parameter, pressure plays a unique role in the studies of quantum materials, because the application of pressure on the materials can induce significant changes in their lattice parameters, electronic structure and corresponding physical properties. This allows to control the properties of a quantum system, explore new phenomena and understand the underlying physics that may be hidden or inaccessible under ambient conditions.

Our mission centers around the exploration of new phenomena and the study of physics in quantum materials. We are committed to employing advanced high-pressure techniques to conduct cutting-edge research projects. Through our dedicated efforts, we aim to advance our understanding of quantum materials, particularly those that exhibit superconducting or related electronic states.
