Holographic spin networks from tensor network states
Sukhwinder Singh, Nathan A. McMahon, Gavin K. Brennen
In the holographic correspondence of quantum gravity, a global onsite symmetry at the boundary generally translates to a local gauge symmetry in the bulk. We describe one way how t…
Tensor network state correspondence and holography
Sukhwinder Singh
In recent years, tensor network states have emerged as a very useful conceptual and simulation framework to study quantum many-body systems at low energies. In this paper, we descr…
Simulation of braiding anyons using Matrix Product States
Babatunde M. Ayeni, Sukhwinder Singh, Robert N. C. Pfeifer +1
Anyons exist as point like particles in two dimensions and carry braid statistics which enable interactions that are independent of the distance between the particles. Except for a…
Finite Density Matrix Renormalisation Group Algorithm for Anyonic Systems
Robert N. C. Pfeifer, Sukhwinder Singh
The numerical study of anyonic systems is known to be highly challenging due to their non-bosonic, non-fermionic particle exchange statistics, and with the exception of certain mod…
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…
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…
