Gradient methods for variational optimization of projected entangled-pair states
Laurens Vanderstraeten, Jutho Haegeman, Philippe Corboz +1
We present a conjugate-gradient method for the ground-state optimization of projected entangled-pair states (PEPS) in the thermodynamic limit, as a direct implementation of the var…

Quasi-particle interactions in frustrated Heisenberg chains
Laurens Vanderstraeten, Jutho Haegeman, Frank Verstraete +1
Interactions between elementary excitations in quasi-one dimensional antiferromagnets are of experimental relevance and their quantitative theoretical treatment has been a theoreti…
