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…
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…
Entanglement scaling for
Bram Vanhecke, Frank Verstraete, Karel Van Acoleyen
We study the model in dimensions at criticality, and effectuate a simultaneous scaling of UV and IR physics. We demonstrate that the order parameter , the correlati…
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…
