Re: 'Strange metals' point to a whole new way to understand electricity
#2Progress 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.

#4IANAP, 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.

#5so 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'.

A regular particle isn't really emergent, it corresponds 1:1 to the excitation of the field
Quasiparticles arise out of a collection of particles, that's why they're emergent

Yeah, electrons are waves and experience quantum tunneling which we see in high density electronics and specifically apply in flash memories.

#8The article says that resisivity in normal metals follows a quadratic curve, but the article also says that it follows an exponential curve. Does anyone know which it right?

QFT is perfect for a single particle, but it gets harder to describe the behavior of particles en masse. It's super hard to find simplifications that reveal emergent behavior.

Yeah, everything is just like photons, everything is a wave/particle
