Chiral projected entangled-pair state with topological order
Shuo Yang, Thorsten B. Wahl, Hong-Hao Tu +2
We show that projected entangled-pair states (PEPS) can describe chiral topologically ordered phases. For that, we construct a simple PEPS for spin-1/2 particles in a two-dimension…
Shadows of Anyons
Jutho Haegeman, Valentin Zauner, Norbert Schuch +1
The eigenvalue structure of the quantum transfer matrix is known to encode essential information about the elementary excitations. Here we study transfer matrices of quantum states…
Characterizing Topological Order with Matrix Product Operators
Mehmet Burak Şahinoğlu, Dominic Williamson, Nick Bultinck +4
One of the most striking features of quantum phases that exhibit topological order is the presence of long range entanglement that cannot be detected by any local order parameter.…
Semionic resonating valence bond states
Mohsin Iqbal, Didier Poilblanc, Norbert Schuch
The nature of the kagome Heisenberg antiferromagnet (HAFM) is under ongoing debate. While recent evidence points towards a Z_2 topological spin liquid, the exact nature of the topo…
Transfer Matrices and Excitations with Matrix Product States
V. Zauner, D. Draxler, L. Vanderstraeten +6
We investigate the relation between static correlation functions in the ground state of local quantum many-body Hamiltonians and the dispersion relations of the corresponding low e…
Gauging quantum states: from global to local symmetries in many-body systems
Jutho Haegeman, Karel Van Acoleyen, Norbert Schuch +2
We present an operational procedure to transform global symmetries into local symmetries at the level of individual quantum states, as opposed to typical gauging prescriptions for…
