On April 14th, from Instituto de Física Teórica, Universidad Autonoma de Madrid and Consejo Superior de Investigaciones Científicas, in Spain, Dr. Mario Flory gave a seminar talk about the connection between the AdS/CFT correspondence and condensed matter physics.

In the first half of the talk, he briefly reviewed the ideas of the correspondence and its history. The most important breakthrough is that Juan Maldacena first proposed the AdS/CFT in the late '90s. It is known that the entropy of the black hole is proportional to its area, so that this feature suggests a holographic principle. The AdS/CFT correspondence serves a better understanding of this principle by connecting strongly coupled CFTs to classical gravity.

In the second half, Dr. Flory addresses the important application of the correspondence to condensed matter physics. Because of the AdS/CFT correspondence, the problems of the Kondo model in condensed matter physics can be tackled by solving gravity problems. He specifically discussed the entanglement problem through the correspondence in detail. We thank Dr. Flory for giving an excellent talk.
