  "A geometrical derivation of entanglement entropy using the AdS/CFT  
correspondence"

  Abstract



The entanglement entropy of a quantum critical system in d+1- 
dimensions described by a Conformal Field Theory is calculated as the  
"area" of a d-dimensional minimal surface in a d+2-dimensional Anti- 
deSitter space. This formulation is analogous to the Bekenstein- 
Hawking formula for the black hole entropy.
