Phase Transitions in Networks of Quantum Critical Systems - Softcover

Inhaltsangabe

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.
