Progress is seeing the cloud from the particles I reckon. I am excited to see practical uses of measuring entanglement to push forward materials research. I’m curious about what other materials have linear changes related to temperature or other inputs, seems uncommon.

IANAP, but I thought that quantum field theory (which isn't incredibly controversial) already treats particles as merely emergent convenient ways to describe common excitations of the fields. I'm surprised it isn't mentioned here at all.

so electrons are just like photons being a wave/particle? The article seems to suggest in strange metals their particle properties are absent and only 'electron field' gradients move, like if electrons exhanged their 'charge'.
