Identifying quantum phases from injectivity of symmetric matrix product states
Sukhwinder Singh
Given a local gapped Hamiltonian with a global symmetry on a one dimensional lattice we describe a method to identify if the Hamiltonian belongs to a quantum phase in which the sym…

Tensor network states and algorithms in the presence of a global U(1) symmetry
Sukhwinder Singh, Robert N. C. Pfeifer, Guifre Vidal
Tensor network decompositions offer an efficient description of certain many-body states of a lattice system and are the basis of a wealth of numerical simulation algorithms. In a…
