Prof. Hyun Seok Yang (CQUeST, Sogang Univ.)20/02/2012, 19:00We will show how cosmic inflation can be generated by conformal Hamiltonian system in emergent gravity. We will also discuss a background independent completion of the spacetime generation through the cosmic inflation.Go to contribution page

Dr Arman Shafieloo (IEU, Ewha W. Univ.)20/02/2012, 19:30Nature of dark energy is one of the biggest unknowns of the modern cosmology. I will summarizes general attempts to reconstruct the expansion history of the universe and to probe the nature of dark energy. Reconstruction methods can be broadly classified into parametric and non-parametric approaches. Presenting the analysis of the most recent cosmological data, some pitfalls of each approach...Go to contribution page

Dr Kanghoon Lee (CQUeST)20/02/2012, 20:20This talk aims to illustrate our recent supersymmetric extension of double field theory and its connection to supergravity. In terms of novel stringy differential geometry we propose, our action consists of five simple terms - two bosonic plus three fermionic - and manifests not only diffeomorphism and one-form gauge symmetry of B-field, but also O(10,10) T-duality as well as a direct product...Go to contribution page

Dr Jaehoon Jeong (Yonsei Univ.)20/02/2012, 20:50We construct the gravity background which describes the dual field theory with aging invariance. We choose the decay modes of the bulk scalar field in the internal spectator direction to obtain the dissipative behavior of the boundary correlation functions of the dual scalar fields. In particular, the two-time correlation function at zero temperature has the characteristic features of the...Go to contribution page
