Quantum Anomalies Program Seminar: Gökçe Basar, Stony Brook University

Title: “Chiral anomaly, kinetic theory, and the Chiral Magnetic/Vortical Effect” Speaker: Gökçe Basar, Stony Brook University Date: Thursday January 23 Time: 10:30am Place: Seminar Room 313, Simons Center Abstract: I will review the kinetic theory description of chiral fermions, which is suitable for systems that possess weakly interacting quasi-particles. In this picture, the chiral anomaly is captured by the Berry phase. … Read more

Quantum Anomalies Program Seminar: Tigran Kalaydzhyan, Stony Brook University

Title: “Intro: Holographic fluids and superfluids” Speaker: Tigran Kalaydzhyan, Stony Brook University Date: Thursday January 16 Time: 1:00pm Place: Seminar Room 313, Simons Center Abstract: I will present a pedagogical introduction to the fluid-gravity duality. I will start from the intuitive description of the AdS/CFT-correspondence without any use of the string theory, and describe the duality dictionary most suitable for the … Read more
