Maths HEP Lunchtime Seminars: Spatially modulated phases in AdS/CFT
5 October 2012 13:00 in CM221
The AdS/CFT correspondence is a powerful tool to analyse strongly coupled quantum field theories. Over the past few years there has been a surge of activity aimed at finding possible applications to condensed matter systems. One focus has been to holographically realise various kinds of phases via the construction of fascinating new classes of black hole solutions. In this framework, I will discuss the possibility of describing finite temperature phase transitions leading to spontaneous breaking of translational invariance of the dual field theory at strong coupling and finite chemical potential. For the marginally stable case, I will also describe a mechanism which leads to a strong effect in the low frequency optical conductivity, similar to what happens in strange metals.
