Abstract:  
This note contains discussions on entanglement entropy and mutual information in a strongly coupled field theory with a critical point which has a holographic dual. We will discuss analytically, in specific regimes of parameters, how these nonlocal operators behave near critical point. Interestingly we obsrve that the mutual information diverges approaching the critical point with power 1/2 which equals the critical exponent known for this theory.
