Flat holography is stimulated by the success of AdS/CFT and has attracted much attention due to its potential applications in realistic physical processes. In this seminar, I will introduce Carrollian holography in which the dual field theory is assumed to live on the null boundary of asymptotically flat spacetime. At first, I will review basic elements on Carrollian manifold and introduce quantum flux operators which realize various geometric symmetry of Carrollian manifold. Second, I will explore the definition of Carrollian amplitude which is the central object that integrates geometry, quantum effects and holography. At last, I will discuss its potential applications to gravitational physics.
