Chan-Paton gauge enhancement In its most immediate (albeit naive) form, the formulation of the problem of gauge enhancement in M-theory proceeds from the expected double dimensional reduction (2) of the black branes of M-theory (see [HSS18] for a precise account), to those of type IIA string theory, which for black branes looks as follows [To95a,To95b. general relativity and the Landau problem in and ; in particular, the classical geodesics correspond to Larmor orbits in the Landau problem. equivalence between a class of helical, strongly coupled Luttinger liquids and 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.

We classify and construct all the smooth Kaluza-Klein reductions to ten dimensions of the M2- and M5-brane configurations which preserve some of the supersymmetry. The relation among spacetime supersymmetry algebras and the world volume approach to string theory is reviewed. Our analysis is performed in terms of Fourier modes, which do not mix with other operators as time evolves, and whose correlation functions are determined by their two-point functions alone, at leading order in the large-N limit.

Further, in certain cases, the 4d black hole can be lifted to a solution of 5d gravity [20][21][22], in which case its near horizon geometry contains a BTZ black hole in AdS 3 space-time.
