Condensed concepts

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

A piece of gold metal is shiny but a single gold atom is not. Tin is a superconductor but a single tin atom is not. Water is wet but a singl...

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

The two terms are often used interchangeably, but that is not appropriate. Condensed matter physics does not just involve solids but also ph...

There is an interesting preprint Viscosity Bound Violation in Viscoelastic Fermi Liquids   Matthew P. Gochan, Hua Li, Kevin S. Bedell Th...

A major achievement of ultra cold atoms was to simulate the Bose Hubbard model 14 years ago. Progress towards the fermion Hubbard model (b...

I have received a lot of helpful feedback on a recent paper about shear viscosity in strongly interacting quantum fermion fluids. As a resu...

Two weeks ago it was nice to have Meera Parish visit UQ and give a colloquium Fermions in Flatland.  She recently moved to Monash Universit...

This week at UQ there was a fascinating Quantum Science Seminar by Jorg Schmiedmayer, describing some beautiful ultra cold atom experiments....

There is an interesting preprint Breakdown of Fermi liquid description for strongly interacting fermions  Yoav Sagi, Tara E. Drake, Rabin ...

Previously, I posted about possible quantum limits to the shear viscosity in quantum many-body systems. This has attracted a lot of interest...

In a quantum many-body system a key thermodynamic quantity is the charge compressibility, the derivative of the charge density with respect ...

I have really enjoyed this week at the  Australasian Workshop on Emergent Quantum Matter.  My UQ colleague Matt Davis is to be congratulate...

Nandan Pakhira and I recent completed a paper Absence of a quantum limit to charge diffusion in bad metals This work was partly motivated...

Previously I posted about some interesting theory and cold atom experiments that suggest that the spin diffusion constant D has a lower boun...

An important and fundamental question concerning a strongly interacting many-body system is whether there are fundamental limits (lower boun...

Here are the slides for the talk I am giving today at the UQ Physics colloquium. I will show the video Quantum levitation , and discuss wh...

I recently heard a talk by someone working on cold atoms who kept saying again and again that these were strongly correlated systems. I may ...

Next week I am giving the Quantum science seminar at UQ. This is attended by people with diverse interests and backgrounds: cold atoms, cond...

In 2007 Gordon Baym gave a fascinating talk New States of Quantum Matter which is nicely summarised in a short conference paper.  You can w...
