Probes to entropy flow in strange metals

The discovery of an unexpectedly large thermoelectric response in a 2D material establishes its power to probe the entropy carried by its charge carriers in the hotly debated strange metal phase.

The Nernst effect is the thermoelectric analogy to the electrical Hall effect. Whereas the Hall effect measures how much the electrons turn sideways in a magnetic field, the Nernst effect characterizes how strong a sideways electric field is generated by the magnetic field when entropy is transported as a heat flow. Now, writing in Nature Physics, Yusen Yang and collaborators1 indicate a potential new source of the Nernst effect in the strange metal phase of quantum materials.
