Application of Gauge/Gravity Duality to Application of Gauge/Gravity Duality to Condensed matter systems Condensed matter systems An introduction From Black Hole to Superconductor 曾化碧 （渤海大学） （渤海大学） Content • What is AdS/CFT? Applied AdS/CFT • How it works? • Two typical examples of AdS/CMT • Conclusion and future What is Gauge/Gravity duality and the position of it • An important progress in theoritical physics in 20 years. (change the usual understanding of nature) The duality between the largest scale theory and smallest scale theory. Gravity and Quantum field theory Gauge Field Theory and (Quantum) Gravity a) Electromagnetism b) Weak nuclear d) c) Strong nuclear Quantum Gravity: Standard Model String Theory, Loop Quantum Problem: Strong Coupled system in QCD. CMT. Gravity. Gauge Field Theory and Quantum Gravity challenge VS chance a) Electromagnetism b) Weak nuclear ? d) c) Strong nuclear Quantum Gravity: Standard Model String Theory, Loop Quantum Problem: Strong Coupled system in QCD. CMT. Gravity. Motivations • The holographic principle (‘t
