Projected Entangled Pair States with flexible geometry

Siddhartha Patra, Sukhbinder Singh, Román Orús

Projected Entangled Pair States (PEPS) are a class of quantum many-body states that generalize Matrix Product States for one-dimensional systems to higher dimensions. In recent yea…

Dissipative Symmetry-Protected Topological Order

Luan M. Veríssimo, Marcelo L. Lyra, Roman Orus

In this work, we investigate the interplay between dissipation and symmetry-protected topological order. We considered the one-dimensional spin-1 Affleck-Kennedy-Lieb-Tasaki model…

Universal features of entanglement entropy in the honeycomb Hubbard model

Jonathan D'Emidio, Roman Orus, Nicolas Laflorencie +1

The entanglement entropy is a unique probe to reveal universal features of strongly interacting many-body systems. In two or more dimensions these features are subtle, and detectin…

Kitaev honeycomb antiferromagnet in a field: quantum phase diagram for general spin

Saeed S. Jahromi, Max Hörmann, Patrick Adelhardt +4

We combine tensor-network approaches and high-order linked-cluster expansions to investigate the quantum phase diagram of the antiferromagnetic Kitaev's honeycomb model in a magnet…

Thermodynamics of 3D Kitaev quantum spin liquids via tensor networks

Saeed S. Jahromi, Hadi Yarloo, Roman Orus

We study the 3D Kitaev and Kitaev-Heisenberg models respectively on the hyperhoneycomb and hyperoctagon lattices, both at zero and finite-temperature, in the thermodynamic limit. O…

Benchmarking global symmetry in 2d tensor network algorithms

Philipp Schmoll, Roman Orus

We implement and benchmark tensor network algorithms with symmetry for systems in two spatial dimensions and in the thermodynamic limit. Specifically, we implement -…

Topological RVB quantum spin liquid on the ruby lattice

Saeed S. Jahromi, Roman Orus

We construct a short-range resonating valence-bond state (RVB) on the ruby lattice, using projected entangled-pair states (PEPS) with bond dimension . By introducing non-local…

Fine-Grained Tensor Network Methods

Philipp Schmoll, Saeed S. Jahromi, Max Hörmann +3

We develop a strategy for tensor network algorithms that allows to deal very efficiently with lattices of high connectivity. The basic idea is to fine-grain the physical degrees of…
