MSc. (Tech.) Juska Pekkanen was awarded the 2015 Fundamental Physics Special
Recognition Award by the CMS spokepersons Joseph Incandela and Tiziano Camporesi
7.12.2015 at the opening plenary session of CMS Physics Week at CERN. The
special recognition is due to Juska’s appreciated efforts in jet calibration
studies and his major contributions to the recently submitted dijet resonance
search result that is the first public new physics search with 13 TeV
proton-proton collisions (http://arxiv.org/abs/1512.01224).

Teleparallel gravity and the role of inertia in theories of gravity
Abstract: The central role in general relativity is played by the principle of equivalence, which suggests that gravity and inertia are locally indistinguishable, and it is hardcoded into general relativity through the use of the Levi-Civita geometry. In this talk, I will present an interesting work-around to this problem known as teleparallel gravity. It can be understood as a dual theory to general relativity, where gravity is attributed to torsion of spacetime, rather than curvature. As it turns out, in this theory it is possible to separate (non-locally) the problematic inertial contributions from gravity, and define the finite, purely gravitational, action. I will show that this subtraction of the inertial effects closely resembles holographic renormalization, and discuss its applications in holography and modified gravity.

Thermalization in the AdS/CFT duality
Abstract: We study examples of out of equilibrium systems in the context of the AdS/CFT duality. We attempt to draw general conclusions from these studies and in particular will highlight the role of black hole quasinormal frequencies in determining the rate at which these systems approach thermal equilibrium.
