Quantum correction to chaos in Schwarzian theory
Abstract We discuss the quantum correction to chaos in the Schwarzian theory. We carry out the semi-classical analysis of the Schwarzian theory to study Feynman diagrams of the Schwarzian soft mode. We evaluate the contribution of the soft mode to the out-of- time-order correlator up to order 𝒪 (g 4...

| Summary: | Abstract We discuss the quantum correction to chaos in the Schwarzian theory. We carry out the semi-classical analysis of the Schwarzian theory to study Feynman diagrams of the Schwarzian soft mode. We evaluate the contribution of the soft mode to the out-of- time-order correlator up to order 𝒪 (g 4). We show that the quantum correction of order 𝒪 (g 4) by the soft mode decreases the maximum Lyapunov exponent 2 π β $$ \frac{2\pi }{\beta } $$ . |
