An overview of Wavelets and MERA
Speaker(s): Glen Evenbly
Abstract: The use of wavelet-based constructions has led to significant progress in the analytic understanding of holographic tensor networks, such as the multi-scale entanglement renormalization ansatz (MERA). In this talk I will give an overview of the (past and more recently established) connections betwee... read more

PIRSA:17040049  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Hyper-invariant tensor networks and holography
Speaker(s): Glen Evenbly
Abstract: I will propose a new class of tensor network state as a model for the AdS/CFT correspondence and holography. This class shall be demonstrated to retain key features of the multi-scale entanglement renormalization ansatz (MERA), in that they describe quantum states with algebraic correlation functio... read more

PIRSA:15080065  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Tensor Network Renormalization and the MERA
Speaker(s): Glen Evenbly
Abstract: I describe a class of non-perturbative renormalization group (RG) transformations which, when applied to the (discrete time) Euclidean path integrals of a quantum systems on the lattice, can give results consistent with conformal transformations of quantum field theories. In particular, this class o... read more

PIRSA:14110137  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Tensor network renormalization
Speaker(s): Glen Evenbly
Abstract:

I will describe how to define a proper RG flow in the space of
tensor networks, with applications to the evaluation of classical
partition functions, euclidean path integrals, and overlaps of tensor
network states.

PIRSA:13050041  ( MP4 Medium Res , MP4 Low Res , MP3 , PDF ) Which Format?
Directed Influence in the RG Flow
Speaker(s): Glen Evenbly
Abstract: Given two lattice Hamiltonians H_1 and H_2 that are identical everywhere except on a local region R of the lattice, we propose a relationship between their ground states psi_1 and psi_2.  Specifically, assuming the states can be represented as multi-scale entanglement renormalization ansatz... read more

PIRSA:11100098  ( MP4 Medium Res , MP4 Low Res , MP3 , PDF ) Which Format?
MERA and CFT
Speaker(s): Glen Evenbly
Abstract: The MERA offers a powerful variational approach to quantum field theory. While the continuous MERA may allow us to directly address field theories in the continuum, the MERA on the lattice has already demonstrated its ability to characterize conformal field theories. In this talk I will explain how ... read more

PIRSA:10110076  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Holographic Branching and Entanglement Renormalization
Speaker(s): Glen Evenbly
Abstract: Entanglement renormalization is a coarse-graining transformation for quantum lattice systems. It produces the multi-scale entanglement renormalization ansatz, a tensor network state used to represent ground states of strongly correlated systems in one and two spatial dimensions. In 1D, the MERA is k... read more
