"We study 3d N=2 Chern-Simons quiver theories on Σg×S¹. Using localization results, we examine their twisted index in the large rank limit and requiring the resulting matrix models to be local, find quiver theories that have quivers in one-to-one correspondence with the affine-ADE Dynkin diagrams. We give explicit results for the twisted index of affine-AD quivers, leading to certain predictions for their holographic duals. If time and interest permits, we will work out the result for D₄ quiver."

"Global Climate Models of increasing sophistication have come to dominate climate studies. Yet, simplified climate models continue to offer insights in the climate system. This talk focusses on the use of idealised models to study how surface temperature and the water cycle respond to perturbations in different radiation components at the surface. Simple quantitative driver-response relationships derived from these models are shown to have wide explanatory power: reconciling “paradoxes” in observations of climate variables, understanding certain biases in GCM output, and why the sensitivity of the water cycle is different to greenhouse gases and aerosols. This also allows for the rapid formulation and first-order studies of new climate change scenarios."

"At high enough baryon densities, when the nucleons are crushed into quark matter, the quark matter that results is expected to be in one of a family of superconducting phases at low temperatures. Such kind of matter could be there in the core of neutron stars. Neutron stars are also expected to have a strong magnetic field. There has been a lot of progress during the last few years on the properties of quark matter in the presence of magnetic field. In the present talk, I shall discuss the current status of color superconducting phase of quark matter in the presence of strong magnetic field. Imposition of charge neutrality conditions here leads to 'gapless' modes. Possible consequences of such modes on transport properties of quark matter will be discussed."
