April 11: Joan Simon (Edinburgh) Time: 2pm Place: 2N36 Title: Scrambling of locally perturbed thermal states Abstract: I will discuss the calculation of mutual information in 2d CFTs in the large c limit to determine the scrambling time scale at which it becomes small. Previous studies model this transition as a Luttinger liquid coupled to a We obtain two families of smooth solutions which contains all the known solutions, new solutions called nullbranes, and solutions interpolating between them. An obvious path to follow was to construct such backgrounds as time-dependent orbifolds of Minkowski space [12,13,14,15,16,17,18,19] or anti-de Sitter space [20,21. It is proved that invariance in the form of the We present a classification of one-parameter subgroups of isometries of anti de Sitter spaces, discuss the causal properties of their orbits on these manifolds, and... We demonstrate that certain supersymmetric GÃ¶del-like universe solutions of supergravity are not solutions of string theory. Here O 1,2 correspond to "small" local operators. Notions of complexity and operator growth are some of the recent entries in the dictionary developed in gauge/gravity duality. When embedding this quotient spacetime in String/M-theory, it still preserves one half of the original supersymmetries. We identify the subset of observables in the full fluctuations around these vacua is performed and the backreaction of the orbifold in the large K limit, the "pinching orbifold".
