Tensor-network approach to phase transitions in string-net models
Alexis Schotte, Jose Carrasco, Bram Vanhecke +4
We use a recently proposed class of tensor-network states to study phase transitions in string-net models. These states encode the genuine features of the string-net condensate suc…

A scaling hypothesis for matrix product states
Bram Vanhecke, Jutho Haegeman, Karel Van Acoleyen +2
We revisit the question of describing critical spin systems and field theories using matrix product states, and formulate a scaling hypothesis in terms of operators, eigenvalues of…

Approaching the Kosterlitz-Thouless transition for the classical XY model with tensor networks
Laurens Vanderstraeten, Bram Vanhecke, Andreas M. Laeuchli +1
We apply variational tensor-network methods for simulating the Kosterlitz-Thouless phase transition in the classical two-dimensional XY model. In particular, using uniform matrix p…
