Kagome metals with van Hove singularities near the Fermi level can host intriguing quantum phenomena such as chiral loop currents, electronic nematicity, and unconventional superconductivity. However, to our best knowledge, unconventional magnetic states driven by van Hove singularities–like spin-density waves–have not been observed experimentally in kagome metals. Here, we report ...

There are substantial changes in soil structure in regions where the soil is freezing. Water movements in the freezing soil introduce level changes beyond what can be expected by the expansion of water when it freezes. The impact of frost heave is seasonal damage to our built environment ...
