Lattice regularisation and entanglement structure of the Gross-Neveu model
Gertian Roose, Nick Bultinck, Laurens Vanderstraeten +3
We construct a Hamiltonian lattice regularisation of the -flavour Gross-Neveu model that manifestly respects the full symmetry, preventing the appearance of any…
Robustness of critical U(1) spin liquids and emergent symmetries in tensor networks
Henrik Dreyer, Laurens Vanderstraeten, Ji-Yao Chen +2
We study the response of critical Resonating Valence Bond (RVB) spin liquids to doping with longer-range singlets, and more generally of U(1)-symmetric tensor networks to non-symme…
Solving frustrated Ising models using tensor networks
Bram Vanhecke, Jeanne Colbois, Laurens Vanderstraeten +2
Motivated by the recent success of tensor networks to calculate the residual entropy of spin ice and kagome Ising models, we develop a general framework to study frustrated Ising m…
Efficient variational contraction of two-dimensional tensor networks with a non-trivial unit cell
A. Nietner, B. Vanhecke, F. Verstraete +2
Tensor network states provide an efficient class of states that faithfully capture strongly correlated quantum models and systems in classical statistical mechanics. While tensor n…
Tangent-space methods for truncating uniform MPS
Bram Vanhecke, Maarten Van Damme, Jutho Haegeman +2
A central primitive in quantum tensor network simulations is the problem of approximating a matrix product state with one of a lower bond dimension. This problem forms the central…
