Tensor networks for complex quantum systems
Roman Orus
Tensor network states and methods have erupted in recent years. Originally developed in the context of condensed matter physics and based on renormalization group ideas, tensor net…
Quantum criticality on a chiral ladder: an iDMRG study
Philipp Schmoll, Andreas Haller, Matteo Rizzi +1
In this paper we study the ground state properties of a ladder Hamiltonian with chiral -invariant spin interactions, a possible first step towards the construction of truly…
A programming guide for tensor networks with global symmetry
Philipp Schmoll, Sukhbinder Singh, Matteo Rizzi +1
This paper is a manual with tips and tricks for programming tensor network algorithms with global symmetry. We focus on practical details that are many times overlooked whe…
Stabilization of three-dimensional charge order in YBaCuO via epitaxial growth
M. Bluschke, A. Frano, E. Schierle +12
Incommensurate charge order (CO) has been identified as the leading competitor of high-temperature superconductivity in all major families of layered copper oxides, but the perplex…
A universal tensor network algorithm for any infinite lattice
Saeed S. Jahromi, Roman Orus
We present a general graph-based Projected Entangled-Pair State (gPEPS) algorithm to approximate ground states of nearest-neighbor local Hamiltonians on any lattice or graph of inf…
Spin- Heisenberg antiferromagnet on the star lattice: Competing valence-bond-solid phases studied by means of tensor networks
Saeed S. Jahromi, Roman Orus
Using the infinite Projected Entangled Pair States (iPEPS) algorithm, we study the ground-state properties of the spin- quantum Heisenberg antiferromagnet on the star lattice…
