Prof Bingyang Cao, as the leading Guest Editors, is starting up a Journal of Physics: Condensed Matter (IOP Publishing) Focus on Tsinghua University: Condensed Matter Physics for Energy. This Institutional Focus Collection aims to collect the latest research results and insights from researchers at Tsinghua University, with strong comprehensive strength and great reputation in both condensed matter physics and energy research. We encourage high-quality submissions and hope to provide fundamental physics advances to promote the development of energy technologies. Focus details can be found at: https://iopscience.iop.org/collections/jpcm-230516-234.
