Simulating thermal density operators with cluster expansions and tensor networks
Bram Vanhecke, David Devoogdt, Frank Verstraete +1
We provide an efficient approximation for the exponential of a local operator in quantum spin systems using tensor-network representations of a cluster expansion. We benchmark this…
The Chiral Gross-Neveu model on the lattice via a Landau-forbidden phase transition
Gertian Roose, Jutho Haegeman, Karel Van Acoleyen +2
We study the phase diagram of the -dimensional Gross-Neveu model with both and interaction terms on a spatial lattice. The continuous…
Variational methods for contracting projected entangled-pair states
Laurens Vanderstraeten, Lander Burgelman, Boris Ponsioen +5
The norms or expectation values of infinite projected entangled-pair states (PEPS) cannot be computed exactly, and approximation algorithms have to be applied. In the last years, m…
Direct sampling of projected entangled-pair states
Tom Vieijra, Jutho Haegeman, Frank Verstraete +1
Variational Monte Carlo studies employing projected entangled-pair states (PEPS) have recently shown that they can provide answers on long-standing questions such as the nature of…
Efficient MPS methods for extracting spectral information on rings and cylinders
Maarten Van Damme, Robijn Vanhove, Jutho Haegeman +2
Based on the MPS formalism, we introduce an ansatz for capturing excited states in finite systems with open boundary conditions, providing a very efficient method for computing, e.…
A scaling hypothesis for projected entangled-pair states
Bram Vanhecke, Juraj Hasik, Frank Verstraete +1
We introduce a new paradigm for scaling simulations with projected entangled-pair states (PEPS) for critical strongly-correlated systems, allowing for reliable extrapolations of PE…
