Emergence of ferromagnetism at onset Kondo breakdown in moiré bilayer lattices (phys.org) 8 points by wglb 2y ago ↗ HN
[–] Mithriil 2y ago ↗ The graph in the first figure shows negative Kelvin.. Can someone explain how that is possible? [–] wbl 2y ago ↗ Temperature measures entropy as a systems energy changes. This is a system where the high energy state is less entropic. [–] sadhorse 2y ago ↗ Is this related to lasers behaving as as a body with negative temperature when they manage to heat something to a hotter temperature by radiation?
