Quantum MERA Channels
Full text linkTensor networks representations of many-body quantum systems can be described
in terms of quantum channels. We focus on channels associated with the
Multi-scale Entanglement Renormalization Ansatz (MERA) tensor network that has
been recently introduced to efficiently describe critical systems. Our approach
allows us to compute the MERA correspondent to the thermodynamic limit of a
critical system introducing a transfer matrix formalism, and to relate the
system critical exponents to the convergence rates of the associated channels.Comment: 4 pages, 2 figure
Critical exponents of one-dimensional quantum critical models by means of MERA tensor network
Full text linkAn algorithm for optimizing the MERA tensor network in an infinite system is
presented. Using this technique we compute the critical exponents of Ising and
XXZ model.Comment: 4 pages, 4 figure
