Entanglement in QFTlar set of quantum systems, it is useful to build some intuition in a more familiar setting. In this and the next section, we will therefore focus our attention on getting some insight into the concept of entanglement and learn some of the techniques which are used to characterize it. The discussion

Entanglement Entropy in CFT2tional integral, it helps to develop some intuition as to where the computation can be carried out explicitly. For a general QFT in . > 2 the computation appears intractable in all but the simplest of cases of free field theories [.]. However, it turns out to be possible to leverage the power of con

Deriving Holographic Entanglement Proposalse that the various known properties of entanglement entropy are satisfied by the holographic construction, this per se does not pin down a precise proposal. Furthermore, it does not explain how the prescription for the computation of entanglement entropy relates to the dynamics of the gravitational

The general class of systems that is of interest in this context is that of many electron systems, which lead to various phases of matter depending on the details of the interactions etc. Over the course of the last few decades, we have come across many exoti

While the microscopic dynamics are prescribed in terms of some fundamental degrees of freedom, if our interest is
