Quantum Chaos Download This review covers developments across disciplines, from high energy physics and gravity through many body physics to quantum information science. these disciplines feature different vocabularies. We propose a new diagnostic for quantum chaos. we show that the time evolution of complexity for a particular type of target state can provide equivalent information about the classical lyapunov exponent and scrambling time as out of time order correlators. Abstract: in this talk i will describe a picture which has emerged over the past few years regarding the statistical interpretation of semiclassical gravity and how this relates to wormholes, averaging and the so called factorization puzzle. We show that isolated "quantum chaotic" systems do in fact relax to states in which observables are well described by statistical mechanics. moreover, we argue that the time evolution itself only plays an auxiliary role as thermalization occurs at the level of individual eigenstates.

IIT Gandhinagar | Physics Seminar/Colloquium Abstract: in this talk i will describe a picture which has emerged over the past few years regarding the statistical interpretation of semiclassical gravity and how this relates to wormholes, averaging and the so called factorization puzzle. We show that isolated "quantum chaotic" systems do in fact relax to states in which observables are well described by statistical mechanics. moreover, we argue that the time evolution itself only plays an auxiliary role as thermalization occurs at the level of individual eigenstates. Applications range from quantum computation to condensed matter physics and quantum gravity. we seek to bridge the approaches of these fields, which define and study complexity using different frameworks and tools. Abstract: several puzzles and issues in quantum gravity are related to the question of what type of high energy information is actually available to low energy observers. in this talk i will try to argue that the best description available to a low energy observer is probably of a statistical nature. One hallmark of chaos is sensitive dependence to initial conditions, the “butterfly effect.” we will discuss recent advances in our understanding of the quantum butterfly effect and its connection to the quantum physics of black holes. I will present a simple picture of how thermalization of isolated systems can occur, with universal properties of chaotic quantum dynamics as the underlying mechanism. a large and growing array of analytic, numerical, and experimental evidence now supports this picture.
