Abstract: Tensor network states are new kinds of variational wavefunctions that help us to understand quantum phases and phase transitions beyond Landau paradigm. In this talk, I will first review the major development of tensor network simulation...

Abstract: I will introduce a new 2d gravity/matrix integral duality. The bulk theory is a two-dimensional string theory defined by coupling two copies of Liouville CFT with central charges c = 13 ± is on the worldsheet. We call this string theory...

Abstract: The large-scale structure of our Universe is well described by a model in which matter is predominantly Cold Dark Matter (CDM). While CDM was initially thought to have trouble reproducing the small scales of our Universe (dwarf galaxies...

Description: During the IAS Amplitudes Group Meetings, we discuss recent results about scattering amplitudes and have pedagogical overview lectures on well-established topics in scattering theory. In this introductory meeting, we will decide on the...

Abstract: The existence of multi black hole solutions in asymptotically flat spacetimes is one of the expectation from the final state conjecture. In this talk, I will present preliminary works in this direction via a semilinear toy model in...
