Condensed concepts

In 1994 superconductivity was discovered in strontium ruthenate (Sr2RuO4). This attracted considerable interest because it had a perovskite...

In honour of International Women's Day, I bring to your attention a fascinating recent piece in The Conversation , Who was Amelia Frank?...

Since the discovery of the iron-based superconductors, it has become clear that the combination of multiple orbitals and strong correlations...

Alejandro Mezio and I just posted a preprint Orbital-selective bad metals due to Hund’s rule and orbital anisotropy: a finite-temperature s...

Over the past two decades, a powerful new technique has been developed to determine quasi-particle properties in strongly correlated electro...

The BCS theory of superconductivity is one of the towering intellectual achievements of the twentieth century. There are many ingredients to...

An important and fascinating issue in many-body physics is the emergence of new energy scales, particularly scales that are orders of magni...

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...

One of most interesting new ideas about quantum matter from the last decade is that of a Hund's metal. This is a strongly correlated met...

It is fun to come up with clever names for new physical phenomena: quark, big bang, Janus , slepton,  chromodynamics, inflation,  squashon, ...

One of the most fundamental and profound concepts in quantum many-body theory is the emergence of low energy scales  that are much smaller t...

Some of my UQ colleagues and Jaime Merino have written a series of nice papers inspired by an organometallic molecular material Mo3S7(dmit)3...

Two key ideas concerning unconventional superconductors are the following. 1. s-wave and p-wave pairing (in momentum space) are associated...

The spin-1 antiferromagnetic Heisenberg chain provides a nice example of emergence in a quantum many-body system. Specifically, there are t...

Last week in Ljubljana, I had a nice discussion with Denis Arčon about this paper concerning fullerenes, A3C60 where A = alkali metal. Opt...

There is a nice preprint Strong Correlations, Strong Coupling and s-wave Superconductivity in Hole-doped BaFe2As2 Single Crystals  F. Hard...

In Telluride Francesco Paesani gave a nice talk about his work on metal-organic-frameworks , including those that exhibit spin crossover. ...

Five years ago, Antoine Georges and collaborators invoked the metaphor of the greek god Janus to represent the "two-faced" effects...

A wonderful thing about the web is that now there is so much material online. A pioneer in putting all their seminars and colloquia online i...

I think one of the most interesting ideas to emerge in the theory of correlated electron materials over the past five years is that of a Hun...
