Heat flows through matter like water through pipes: sometimes fast, sometimes barely. Engineers seek materials that almost don't let heat pass — like clogged pipes. Such insulators are vital for energy saving and devices that turn heat into electricity. The neural network KappaFormer quickly evaluates the "throughput" of an atomic structure.

In the depths of a diamond crystal, studded with NV centers, a symphony slumbers. Each defect is like a tuning fork, ready to respond to a passing acoustic wave. But alone, their voices are barely audible: the spin-phonon coupling is weaker than a whisper. A maestro is needed, one who can turn timid vibrations into a resounding choir.
