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 -…
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…
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…
