A complex network description of thermal quantum states in the Ising spin chain
Bhuvanesh Sundar, Marc Andrew Valdez, Lincoln D. Carr +1
We use network analysis to describe and characterize an archetypal quantum system - an Ising spin chain in a transverse magnetic field. We analyze weighted networks for this quantu…

Quantifying Complexity in Quantum Phase Transitions via Mutual Information Complex Networks
Marc Andrew Valdez, Daniel Jaschke, David L. Vargas +1
We quantify the emergent complexity of quantum states near quantum critical points on regular 1D lattices, via complex network measures based on quantum mutual information as the a…
