D0-brane matrix model and holography
Masanori Hanada
(University of Surrey)
Abstract:
The D0-brane matrix model (the BFSS matrix model and the BMN matrix model) can describe various objects including type IIA black zero-brane, M-theory black hole, M2-branes and M5-branes. We study this theory from several different angles. We put the emphasis on the importance of the dynamics of eigenvalues of matrices, and more generally, color degrees of freedom. Furthermore we explain how the Euclidean theory can be studied by using the Monte Carlo method, and discuss the future directions. If you have a good idea we can test it on computer together!

Density matrix for the 2D black hole from an integrable spin chain
Sergei Lukyanov
(Rutgers and Kharkevich IITP)
Abstract:
Twenty years ago Maldacena, Ooguri and Son constructed a modular invariant partition function for the Euclidean black hole (cigar) NLSM. They also proposed an expression for the corresponding density matrix.
This result played a key role in the formulation of
the remarkable conjecture by Ikhlef, Jacobsen and Saleur that the Euclidean black hole NLSM underlies the critical behaviour of a certain integrable spin chain.
In this talk we critically reexamine the above proposals.
The talk is based on the recent (unpublished) joint work with V. Bazhanov and G. Kotousov.
