Heating electrons in twisted MoS$_2$ counterintuitively freezes an itinerant quantum liquid into a localized Wigner crystal, proving that isospin entropy can invert conventional thermodynamic melting in moiré flat bands.

While hydrostatic pressure routinely degrades polarization in conventional ferroelectrics, squeezing bilayer boron nitride actually amplifies its switchable polarization by 80%.
