Automatic transformation of irreducible representations for efficient contraction of tensors with cyclic group symmetry
Yang Gao, Phillip Helms, Garnet Kin-Lic Chan +1
Tensor contractions are ubiquitous in computational chemistry and physics, where tensors generally represent states or operators and contractions express the algebra of these quant…

Dynamical Phase Transitions in a 2D Classical Nonequilibrium Model via 2D Tensor Networks
Phillip Helms, Garnet Kin-Lic Chan
We demonstrate the power of 2D tensor networks for obtaining large deviation functions of dynamical observables in a classical nonequilibrium setting. Using these methods, we analy…
