Abstract
In this dissertation, we studied quantum entanglement in the context of many-body physics. Based on quasi-free bipartite fermionic models, we were able to study the entanglement entropy and its spectrum in various quantum phases. Particularly, we studied the p wave superconducting paring states, which contain quantum critical phases with different Fermi surface topology, and we also studied the p

wave superconducting paring states, which contain not only quantum critical phases but also quantum topological phases.
