Quantum correlation is a fundamental feature of quantum mechanics that distinguishes quantum systems from the classical macroscopic world. Quantum correlation can be categorized into spatial and temporal quantum correlations. A well-known example of spatial quantum correlation is quantum entanglement, which has played a crucial role in advancing our understanding of quantum mechanics while also serving as a key resource for cutting-edge quantum technologies, such as quantum communication, quantum computing, and quantum sensing. Research on quantum correlations has recently extended to the temporal domain, exploring the characteristics of quantum correlations across different time points and their potential applications in quantum technologies.

Single crystals exhibiting glass-like thermal conductivity are exceptionally rare because of the fundamentally different heat conduction mechanisms and atomic structures between crystals and glasses. Typically, above the Debye temperature, the thermal conductivities of crystals decrease with increasing temperature until they asymptotically approach a lower limit. In contrast, the thermal conductivities of amorphous materials increase with rising temperature due to their lack of long-range order.

Multiferroic materials are a class of multifunctional materials that exhibit both ferroelectricity and magnetic ordering. Traditional multiferroic materials are typically classified into two categories. In type-I multiferroics, ferroelectricity originates from orbital degeneracy lifting due to broken crystal symmetry, resulting in weak magnetoelectric coupling between spontaneous polarization and magnetic order. In type-II multiferroics, magnetic order and polarization are directly correlated via spin-orbit coupling mechanisms, such as the Dzyaloshinskii-Moriya interaction, which theoretically enables high magnetoelectric coupling coefficients. However, in most transition metal compounds, the strength of spin-orbit coupling is relatively weak (on the order of ~10 meV), making it challenging to achieve large magnetoelectric coupling coefficients.

The recipients of the 11th Chinese Chemical Society-Royal Society of Chemistry Young Chemist Award were recently announced by the Chinese Chemical Society (CCS), with Liu Leo LIU, Associate Professor of the Department of Chemistry at the Southern University of Science and Technology (SUSTech), being recognized with this honor.
