# Quantum dissection of a covalent bond with the entanglement spectrum

@article{Tubman2014QuantumDO, title={Quantum dissection of a covalent bond with the entanglement spectrum}, author={Norm M. Tubman and D ChangMo Yang}, journal={arXiv: Strongly Correlated Electrons}, year={2014} }

We propose that spatial density matrices, which are singularly important in the study of quantum entanglement, encode the electronic fluctuations and correlations responsible for covalent bonding. From these density matrices, we develop tools that allow us to analyse how many body wave functions can be broken up into real space pieces. We apply these tools to the first row dimers, and in particular, we address the conflicting evidence in the literature about the presence of an inverted fourth…

A complete electronic band theory is proposed, which builds on the conventional band theory of electrons, highlighting the link between the topology and local chemical bonding and can be used to predict many more topological insulators.

This work shows that a useful paradigm for generating efficient selected CI/exact diagonalization algorithms is driven by fast sorting algorithms, much in the same way iterative diagonalization is based on the paradigm of matrix vector multipli- cation.

It is proposed that the low-lying entanglement spectrum can be used as a "fingerprint" to identify topological order and is compared with a generic 5/2 state obtained by finite-size diagonalization of the second-Landau-level-projected Coulomb interactions.

The paper accounts for the author's activity in developing bond order and valence indices since the early 80s, and shows the sufficient conditions under which the bond order index of a homonuclear diatomics is equal to the “chemist's bond order,” i.e., the half of the difference between the number of electrons occupying bonding and antibonding orbitals.
