Previously I posted about the challenge of understanding the colossal thermoelectric effect in FeSb2 and the puzzles of the classic Kondo in...

Here are a couple of things I find surprising about the electronic transport properties of materials. 1. One cannot simply have materials,...

On tuesday I had nice discussion with Raghu Mahajan, Maissam Barkeshli, and Sean Hartnoll about their recent preprint  Non-Fermi liquids and...

Jaime Merino and I just finished a paper Effective Hamiltonian for the electronic properties of the quasi-one-dimensional material Li0.9Mo6O...

The graph below shows the temperature dependence of the Nernst signal measured in the normal metallic state of a family of electron doped cu...

Several earlier posts discussed the thermoelectric effect in strongly correlated electron materials. The Seebeck coefficient S is a quantit...

There is a nice preprint,  Thermoelectric Power of the YbT2Zn20 (T = Fe, Ru, Os, Ir, Rh, and Co) Heavy Fermions  by E. D. Mun, S. Jia, S. L....

The Nernst effect is a thermal conduction analogue of the Hall effect for electrical conductivity, i.e., it measures the transverse electric...

What is so unique about the optimal doping at which the superconducting transition temperature is a maximum in the cuprates? There is an in...

The linear chain compound Li0.9Mo6O17 exhibits a subtle competition between superconductivity, a "bad" metal, and a strange "...

I have been reading through the nice review Finite temperature properties of doped antiferromagnets by Jaklic and Prelovsek from 2000. They...

Thermoelectric materials  are of significant technological interest and present some fundamental scientific questions. An extremely useful ...

A key question concerning the cuprate superconductors is what is the relationship between the pseudogap state and superconductivity? I prev...

There is a nice paper in Science this week which provides experimental evidence for gapless spin excitations (possibly deconfined spinons) ...
