Condensed concepts

And why is it so amazing? Surprises [about physics in two dimensions] occurred in the 1980s when it became possible to study Landau levels ...

A long-standing question for superconductivity in organic charge transfer salts concerns the symmetry of the superconducting order parameter...

A definitive experimental signature of the crossover from a Fermi liquid metal to a bad metal is the disappearance of a Drude peak in the op...

Previously, I have posted about how in certain contexts one can relate non-equilibrium transport quantities to equilibrium thermodynamic qua...

It is hard to believe that we really don't understand the basic issues that I am going to discuss. Resitivity occurs in a metal becaus...

Superconducting organic charge transfer salts exhibit many signatures of strong electron correlations: Mott insulator, bad metal, renormalis...

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

Although I have written several papers about it I still struggle to understand the Berry phase and how it is or may be manifested in solids....

Earlier this year Jure Kokalj brought to my attention an interesting PRL Quantum Critical Transport near the Mott Transition by H. Terlets...

Understanding the Hall effect in strongly correlated electron materials is a challenge. In simple metals, the Hall coefficient R_H is, to a ...

I used to regularly write posts about charge transport in organic electronic materials . Some of these generated lively discussion in the co...

Jure Kokalj, Nigel Hussey, and I have just completed a paper, Transport properties of the metallic state of overdoped cuprate superconductor...

Solid state physics text books tell us that Matthiessen's rule is obeyed by simple metals: the temperature dependent resistivity is the ...

There is an interesting preprint,  Wigner-Mott scaling of transport near the two-dimensional metal-insulator transition  by M. M. Radonjic, ...

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

Ultimately much of quantum many-body theory concerns calculating correlation functions which are measurable. For example, the conductivity c...
