Matrix product states for anyonic systems and efficient simulation of dynamics
Sukhwinder Singh, Robert N. C. Pfeifer, Guifre Vidal +1
Matrix product states (MPS) have proven to be a very successful tool to study lattice systems with local degrees of freedom such as spins or bosons. Topologically ordered systems c…
Improving the efficiency of variational tensor network algorithms
Glen Evenbly, Robert N. C. Pfeifer
We present several results relating to the contraction of generic tensor networks and discuss their application to the simulation of quantum many-body systems using variational app…
Measures of entanglement in non-Abelian anyonic systems
Robert N. C. Pfeifer
Bipartite entanglement entropies, calculated from the reduced density matrix of a subsystem, provide a description of the resources available within a system for performing quantum…
Faster identification of optimal contraction sequences for tensor networks
Robert N. C. Pfeifer, Jutho Haegeman, Frank Verstraete
The efficient evaluation of tensor expressions involving sums over multiple indices is of significant importance to many fields of research, including quantum many-body physics, lo…
