Explores gauge symmetry, amplitudes, black holes, and fluids, highlighting the interplay between redundancy, diffeomorphisms, and the double copy phenomenon.
Explores the concept of scrambling in quantum chaotic systems, connecting classical chaos to quantum chaos and emphasizing sensitivity to initial conditions.
Introduces scalar gravity, covering covariant derivatives, Ricci tensor, Einstein Equivalence Principle, and the generalization of Newtonian gravity equations.
