A Flexible Power Method for Solving Infinite Dimensional Tensor Eigenvalue Problems

  title={A Flexible Power Method for Solving Infinite Dimensional Tensor Eigenvalue Problems},
  author={Roel Van Beeumen and Lana Perisa and Daniel Kressner and Chao Yang},
Abstract. We propose a flexible power method for computing the leftmost, i.e., algebraically smallest, eigenvalue of an infinite dimensional tensor eigenvalue problem, Hx = λx, where the infinite dimensional symmetric matrix H exhibits a translational invariant structure. We assume the smallest eigenvalue of H is simple and apply a power iteration of e with the eigenvector represented in a compact way as a translational invariant infinite Tensor Ring (iTR). Hence, the infinite dimensional…

On algorithms for and computing with the tensor ring decomposition
This paper investigates even lower storage‐cost representations in the tensor ring format, an extension of the Tensor train format with variable end‐ranks, and introduces algorithms for transforming the graph structure of graph‐based tensor formats, with orders of magnitude lower complexity than existing literature.
Variational optimization algorithms for uniform matrix product states
This work combines the density matrix renormalization group with matrix product state tangent space concepts to construct a variational algorithm for finding ground states of one-dimensional quantum lattices in the thermodynamic limit that works very efficiently for Hamiltonians with long-range interactions and for the simulation of two-dimensional models on infinite cylinders.
Time-dependent variational principle for quantum lattices.
We develop a new algorithm based on the time-dependent variational principle applied to matrix product states to efficiently simulate the real- and imaginary-time dynamics for infinite
Quantum Spin Chains
Serious scientific interest in one-dimensional (1-D) physics arose in the early 1960’s. This interest was stimulated by exact as well as accurate numerical solutions to a variety of quantum spin
Matrix product state representations
The freedom in representations with and without translation symmetry are determined, derive respective canonical forms and provide efficient methods for obtaining them.

Invariance under translation is exploited to efficiently simulate one-dimensional quantum lattice systems in the limit of an infinite lattice. Both the computation of the ground state and the
The Bethe ansatz after 75 years
A 1931 result that lay in obscurity for decades, Bethe’s solution to a quantum mechanical model now finds its way into everything from superconductors to string theory.
