Entanglement transitions in translation-invariant tensor networks

Yi-Cheng Wang, Samuel J. Garratt, Ehud Altman

We study the complexity of approximately contracting translation-invariant tensor networks. The computational cost of row-by-row tensor network contraction, which defines a discret…

Self-adjoint extensions with compact resolvent

Yicao Wang

Let $T$ be a densely defined closed symmetric operator with equal deficiency indices in a separable complex Hilbert space $H$ . In this paper, we prove that $T$ has a self-adjoint e…
