Generative modeling with projected entangled-pair states

no code implementations16 Feb 2022 Tom Vieijra, Laurens Vanderstraeten, Frank Verstraete

We argue and demonstrate that projected entangled-pair states (PEPS) outperform matrix product states significantly for the task of generative modeling of datasets with an intrinsic two-dimensional structure such as images.

Efficient MPS methods for extracting spectral information on rings and cylinders

no code implementations22 Feb 2021 Maarten Van Damme, Robijn Vanhove, Jutho Haegeman, Frank Verstraete, Laurens Vanderstraeten

Despite the explicit breaking of translation symmetry by the MPS representation, we show that momentum emerges as a good quantum number, and can be exploited for labeling excitations on top of MPS ground states.

A scaling hypothesis for projected entangled-pair states

no code implementations5 Feb 2021 Bram Vanhecke, Juraj Hasik, Frank Verstraete, Laurens Vanderstraeten

We introduce a new paradigm for scaling simulations with projected entangled-pair states (PEPS) for critical strongly-correlated systems, allowing for reliable extrapolations of PEPS data with relatively small bond dimensions $D$.

Solving frustrated Ising models using tensor networks

no code implementations25 Jun 2020 Bram Vanhecke, Jeanne Colbois, Laurens Vanderstraeten, Frank Verstraete, Frédéric Mila

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 models in terms of infinite tensor networks %, i. e. tensor networks that can be contracted using standard algorithms for infinite systems.
