What is the group of a quantum group? From to MPO representations of
Weronika Wiesiolek, Romain Couvreur, Dmitry Chernyak +2
Generalized symmetries realized by matrix product operators (MPOs) have so far been tied to discrete data leaving continuous symmetries outside the framework. Quantum groups fill t…
The Algebraic Bethe Ansatz and Tensor Networks
Valentin Murg, Vladimir E. Korepin, Frank Verstraete
We describe the Algebraic Bethe Ansatz for the spin-1/2 XXX and XXZ Heisenberg chains with open and periodic boundary conditions in terms of tensor networks. These Bethe eigenstate…
Finite-temperature mutual information in a simple phase transition
J. Wilms, J. Vidal, F. Verstraete +1
We study the finite-temperature behavior of the Lipkin-Meshkov-Glick model, with a focus on correlation properties as measured by the mutual information. The latter, which quantifi…
The computational difficulty of finding MPS ground states
Norbert Schuch, Ignacio Cirac, Frank Verstraete
We determine the computational difficulty of finding ground states of one-dimensional (1D) Hamiltonians which are known to be Matrix Product States (MPS). To this end, we construct…
