Condensed concepts

Quantisation of magnetic flux in a superconductor Magnets and electrical currents produce magnetic fields, regions of space where other magn...

 An example of emergent entities in condensed matter physics are quasiparticles. The concept can be described with the following analogue. W...

Tony Leggett died last week. The New York Times has a nice obituary. One measure of his influence on me is that more than 20 posts on this ...

In two dimensions the phase transition that occurs for superfluids, superconductors, and planar classical magnets is qualitatively different...

Two characteristics of states of matter are associated with them being referred to as quantum. One characteristic is the importance of quant...

Today I am giving a seminar on emergence at the University of Philippines Los Banos, in the Institute of Mathematical Sciences and Physics. ...

 A signature effect associated with superfluidity in liquid helium is that it can climb up the walls of a container and empty the container....

For the marketing plan for my Very Short Introduction , I was recently asked whether there were any significant anniversaries happening in c...

Earlier I suggested that the founders of condensed matter physics were Onnes, Landau, Bardeen, Anderson, and Wilson. I might also add  Bria...

I have now finished my first draft of   Chapter 7  of  Condensed Matter Physics: A Very Short Introduction.  The main purpose of the chapter...

I have now finished my  first draft of chapter 5,  of  Condensed Matter Physics: A Very Short Introduction.  The main purpose of the chapter...

Phil Anderson died two weeks ago. There have been many obituaries, including at The New York Times , Not Even Wrong  (Peter Woit), and Nanos...

I have now finished my first draft of chapter 4, of Condensed Matter Physics: A Very Short Introduction. The main purpose of the chapter i...

When studying quantum many-body theory, sometimes one gets lost in all the indices, functional integrals, Feynman diagrams, ... Then one ca...

An important concept in condensed matter is the role played by scales , i.e. how big or small physical quantities are. Length, time, energy,...

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...

At the weekly condensed matter theory cake meeting today we watched a video of a KITP blackboard talk given by Piers Coleman in 2015. Super...

In my previous post about the 2016 Nobel Prize in Physics I stated that the Kosterlitz-Thouless transition was a classical phase transitio...

Today I am giving a seminar "Emergent quantum matter" in the School of Physics at Central University of Hyderabad . Here are the ...
