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.…
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…
Approximating Gibbs states of local Hamiltonians efficiently with PEPS
András Molnár, Norbert Schuch, Frank Verstraete +1
We analyze the error of approximating Gibbs states of local quantum spin Hamiltonians on lattices with Projected Entangled Pair States (PEPS) as a function of the bond dimension ($…
