Generating Function for Tensor Network Diagrammatic Summation
Wei-Lin Tu, Huan-Kuang Wu, Norbert Schuch +2
The understanding of complex quantum many-body systems has been vastly boosted by tensor network (TN) methods. Among others, excitation spectrum and long-range interacting systems…
SU Chiral Spin Liquid on the Square Lattice: a View from Symmetric PEPS
Ji-Yao Chen, Sylvain Capponi, Alexander Wietek +3
Quantum spin liquids can be faithfully represented and efficiently characterized within the framework of Projected Entangled Pair States (PEPS). Guided by extensive exact diagonali…
Non-Abelian chiral spin liquid in a quantum antiferromagnet revealed by an iPEPS study
Ji-Yao Chen, Laurens Vanderstraeten, Sylvain Capponi +1
Abelian and non-Abelian topological phases exhibiting protected chiral edge modes are ubiquitous in the realm of the Fractional Quantum Hall (FQH) effect. Here, we investigate a sp…
SU(3) trimer resonating-valence-bond state on the square lattice
Xiao-Yu Dong, Ji-Yao Chen, Hong-Hao Tu
We propose and study an SU(3) trimer resonating-valence-bond (tRVB) state with point-group symmetry on the square lattice. By devising a projected entangled-pair state rep…
Discrete lattice symmetry breaking in a two-dimensional frustrated spin-1 Heisenberg model
Ji-Yao Chen, Sylvain Capponi, Didier Poilblanc
Spontaneous discrete symmetry breaking can be described in the framework of Projected Entangled Pair States (PEPS) by linearly superposing local tensors belonging to two (or more)…
