Gauge symmetry of excited states in projected entangled-pair state simulations
Yi Tan, Ji-Yao Chen, Didier Poilblanc +1
While gauge symmetry is a well-established requirement for representing topological orders in projected entangled-pair state (PEPS), its impact on the properties of low-lying excit…
Generating function for projected entangled-pair states
Wei-Lin Tu, Laurens Vanderstraeten, Norbert Schuch +3
Diagrammatic summation is a common bottleneck in modern applications of projected entangled-pair states, especially in computing low-energy excitations of a two-dimensional quantum…
Phase diagram of the chiral SU(3) antiferromagnet on the kagome lattice
Yi Xu, Sylvain Capponi, Ji-Yao Chen +6
Motivated by the search for chiral spin liquids (CSL), we consider a simple model defined on the kagome lattice of interacting SU(3) spins (in the fundamental representation) inclu…
Chiral spin liquids with projected Gaussian fermionic entangled pair states
Sen Niu, Jheng-Wei Li, Ji-Yao Chen +1
We study the parton construction of chiral spin liquids (CSLs) using projected Gaussian fermionic entangled pair states (GfPEPSs). First, we show that GfPEPSs can represent generic…
Entanglement Spectrum as a diagnostic of chirality of Topological Spin Liquids: Analysis of an PEPS
Mark J. Arildsen, Ji-Yao Chen, Norbert Schuch +1
We address the key question of representation of chiral topological quantum states in (2+1) dimensions (i.e., with non-zero chiral central charge) by Projected Entangled Pair State…
Chiral spin liquid in a Kitaev model
Li-Mei Chen, Tyler D. Ellison, Meng Cheng +2
We study a Kitaev model on the honeycomb lattice with nearest neighbor interactions. Based on matrix product state simulations and symmetry considerations, we find e…
