Infinite randomness with continuously varying critical exponents in the random XYZ spin chain

  title={Infinite randomness with continuously varying critical exponents in the random XYZ spin chain},
  author={Brenden Roberts and O. Motrunich},
We study the antiferromagnetic XYZ spin chain with quenched randomness, focusing on a critical line between localized Ising magnetic phases. A previous calculation of Slagle et al., Phys. Rev. B 94, 014205 (2016), using the spectrum-bifurcation renormalization group and assuming marginal many-body localization, proposed that critical indices for Edwards–Anderson correlators vary continuously. In this work we solve the low-energy physics using an unbiased numerically exact tensor network method… Expand

The ITensor Software Library for Tensor Network Calculations
The philosophy behind ITensor, a system for programming tensor network calculations with an interface modeled on tensor diagram notation, and examples of each part of the interface including Index objects, the ITensor product operator, Tensor factorizations, tensor storage types, algorithms for matrix product state (MPS) and matrix product operator (MPO) tensor networks, and the NDTensors library are discussed.
