Condensed concepts

In February 1986, Bednorz and Müller made a stunning discovery: superconductivity at a temperature of 35 K in a doped copper oxide (cuprate)...

Bribie Island, just north of Brisbane. The University of Queensland has just advertised several jobs that may be of interest to readers of t...

"Ecological and evolutionary dynamics are intrinsically entwined. On short timescales, ecological interactions determine the fate and i...

One of the most basic ideas in science is the controlled experiment. A single "independent" variable is changed while all others a...

For an experimentalist one of the "easiest" quantities to measure for a metal is the electrical resistivity. Yet, for a many-body ...

Life is truly amazing! Life is beautiful! ...and it involves quantum many-body physics... There is a beautiful (short) review Heme: Fro...

To my readers my best wishes for the New Year and the new decade! It is worth reflecting on what has been achieved in condensed matter and...

It is that time of year again. I have not made predictions for a few years. For physics this year I predict Experiments for testing Bell ...

There is a nice paper Bad metallic transport in a cold atom Fermi-Hubbard system  Peter T. Brown, Debayan Mitra, Elmer Guardado-Sanchez, R...

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

Several years ago I posted about Density Matrix Embedding Theory  (DMET), proposed as a (computationally cheaper) alternative to Dynamical ...

A central concept of quantum-many body theory is that of coherent quasi-particles. Their key property is a well-defined relationship between...

Ben Powell and I have just advertised for a new postdoc position to work with us at the University of Queensland on strongly correlated ele...

The past two decades have seen impressive advances in Angle-Resolved PhotoEmission Spectroscopy (ARPES). This technique has played a particu...

Since my previous post about the search for a Weyl semimetal in pyrochlore iridates (such as R2Ir2O7, where R=rare earth) read two more inte...

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

In the metallic state of many strongly correlated electron materials, Fermi liquid properties are only observed at relatively low temperatur...

Dynamical Mean-Field Theory (DMFT) has given many insights into the Mott metal-insulator transition in strongly correlated electron material...
