Phase Transitions in Networks of Quantum Critical Systems

By Aleksandr V Sorokin

In this book we explore networks of many-body quantum systems, seeking to describe the new quantum and topological phases that arise from the interaction of individual sites. Tested networks are based on the semi-classical Lipkin-Meshkov-Glick model, and the couplings between different sites of the network are described with either one or two coupling constants. The effect of introducing a second coupling was studied on the example of a one-dimensional chain - an extension of the Su-Schrieffer-Heeger model to the many-body systems -, where the interplay between topological and quantum phases was the main question.
