How to reconcile the definitions of classical and quantum chaos? D. A. Trunin Princeton University, Department of Physics |
|||
Abstract: One of the most popular definitions of quantum chaos is based on the exponential growth of out-of-time-order correlators (OTOC). Unfortunately, this definition has a flaw: it falsely assigns a positive Lyapunov exponent to some integrable systems. In this report, I will explain what causes this discrepancy and suggest a way to correct it. |
