Sadly, I had to cancel my participation in this exciting mini-programme at the last minute, for personal reasons, however I was able to deliver my talk by video-conference and had some interesting exchanges with the audience then and also later via email.<\/p>\n<p><a href=\"http:\/\/blogs.kent.ac.uk\/strongcorrelations\/files\/2015\/05\/qcep-like.png\"><img loading=\"lazy\" class=\"alignnone wp-image-1327 size-medium\" src=\"http:\/\/blogs.kent.ac.uk\/strongcorrelations\/files\/2015\/05\/qcep-like-300x152.png\" alt=\"qcep-like\" width=\"300\" height=\"152\" srcset=\"https:\/\/blogs.kent.ac.uk\/strongcorrelations\/files\/2015\/05\/qcep-like-300x152.png 300w, https:\/\/blogs.kent.ac.uk\/strongcorrelations\/files\/2015\/05\/qcep-like-1024x520.png 1024w, https:\/\/blogs.kent.ac.uk\/strongcorrelations\/files\/2015\/05\/qcep-like-500x254.png 500w, https:\/\/blogs.kent.ac.uk\/strongcorrelations\/files\/2015\/05\/qcep-like.png 1047w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/a><\/p>\n<p align=\"justify\">My talk centred on nodal line re-construction topological transitions in superconductors and specifically on their specific heat signatures. I argued for the existence of a topological transition state which, far from being a special point in the phase diagram, requiring fine-tuning, dominates a vast swathe of it very much like a quantum critical point does. In fact I argued that the nodal reconstruction instablity must be a quantum critical endpoint in very much the same way that the Lifshitz transition is one [see Carr, S. T., Quintanilla, J. &amp; Betouras, J. J. Lifshitz transitions and crystallization of fully polarized dipolar fermions in an anisotropic two-dimensional lattice. <i>Physical Review B<\/i> <b>82,<\/b> 045110 (2010). <a href=\"http:\/\/dx.doi.org\/10.1103\/PhysRevB.82.045110\">10.1103\/PhysRevB.82.045110<\/a>]. I also put forward the idea that such state may be stabilised further by a mechanism akin to the order-by-disorder and that it may even have some hiterto unexplored applications. The latter flows from recent work by <a href=\"http:\/\/blogs.kent.ac.uk\/strongcorrelations\/people\/phil-whittlesea\/\">Phil Whittlesea<\/a> that we hope to publish soon.<\/p>\n<p align=\"justify\">Here is a link to the <a href=\"http:\/\/blogs.kent.ac.uk\/strongcorrelations\/files\/2015\/05\/abstract.pdf\">abstract<\/a> I gave to the organisers before the talk (PDF format).<\/p>\n<p align=\"justify\">\n<ul class=\"kent-social-links\"><li><a href='http:\/\/www.facebook.com\/sharer.php?u=https:\/\/blogs.kent.ac.uk\/strongcorrelations\/2015\/05\/21\/anomalous-thermodynamic-power-laws-at-the-topologial-transition-state-in-nodal-superconductors\/&amp;t=Anomalous thermodynamic power-laws at the topologial transition state in nodal superconductors (talk at MPI-PKS, Dresden)' target='_blank'><i class='ksocial-facebook' title='Share via Facebook'><\/i><\/a><\/li><li><a href='http:\/\/twitter.com\/home?status=Anomalous thermodynamic power-laws at the topologial transition state in nodal superconductors (talk at MPI-PKS, Dresden)%20https:\/\/blogs.kent.ac.uk\/strongcorrelations\/2015\/05\/21\/anomalous-thermodynamic-power-laws-at-the-topologial-transition-state-in-nodal-superconductors\/' target='_blank'><i class='ksocial-twitter' title='Share via Twitter'><\/i><\/a><\/li><li><a href='https:\/\/plus.google.com\/share?url=https:\/\/blogs.kent.ac.uk\/strongcorrelations\/2015\/05\/21\/anomalous-thermodynamic-power-laws-at-the-topologial-transition-state-in-nodal-superconductors\/' target='_blank'><i class='ksocial-google-plus' title='Share via Google Plus'><\/i><\/a><\/li><li><a href='http:\/\/linkedin.com\/shareArticle?mini=true&amp;url=https:\/\/blogs.kent.ac.uk\/strongcorrelations\/2015\/05\/21\/anomalous-thermodynamic-power-laws-at-the-topologial-transition-state-in-nodal-superconductors\/&amp;title=Anomalous thermodynamic power-laws at the topologial transition state in nodal superconductors (talk at MPI-PKS, Dresden)' target='_blank'><i class='ksocial-linkedin' title='Share via Linked In'><\/i><\/a><\/li><li><a href='mailto:content=https:\/\/blogs.kent.ac.uk\/strongcorrelations\/2015\/05\/21\/anomalous-thermodynamic-power-laws-at-the-topologial-transition-state-in-nodal-superconductors\/&amp;title=Anomalous thermodynamic power-laws at the topologial transition state in nodal superconductors (talk at MPI-PKS, Dresden)' target='_blank'><i class='ksocial-email' title='Share via Email'><\/i><\/a><\/li><\/ul>","protected":false},"excerpt":{"rendered":"<p>Yesterday I gave a talk at a mini-programme being organised by Joseph Betouras (Loughboroguh) at the Max Planck Institut for Complex Systems, in Dresden.
