How Tensor Network Renormalization quantifies circuit complexity and why this is a problem of [considerable] gravity
Speaker(s): Bartek Czech
Abstract: According to a recent proposal, in the AdS/CFT correspondence the circuit complexity of a CFT state is dual to the Einstein-Hilbert action of a certain region in the dual space-time. If the proposal is correct, it should be possible to derive Einstein's equations by varying the complexity in a class... read more

Some Information for Assembling Space
Speaker(s): Bartek Czech
Abstract: In holographic duality a gravitational spacetime emerges as an equivalent description of a lower-dimensional conformal field theory (CFT) living on the asymptotic boundary. Traditionally, the dimension not present in the CFT is interpreted in terms of its Renormalisation Group flow. In this talk I e... read more

Tensor Networks from Integral Geometry
Speaker(s): Bartek Czech
Abstract: The analogy between Multi-scale Entanglement Renormalization Ansatz (MERA) and the spatial slice of three-dimensional anti-de Sitter space (AdS3) has motivated a great interest in tensor networks among holographers. I discuss a way to promote this analogy to a rigorous, quantitative, and constru... read more

Three Perspectives on Eternal Inflation
Speaker(s): Bartek Czech
Abstract: I will discuss three ways in which (the string landscape and) eternal inflation is fun: (1) because it motivates revisiting some beautiful, classic calculations; (2) because its global description requires asking novel questions with possible broad ramifications; and (3) because it leads to experime... read more
