Out-of-time-ordered-correlators for the pure inverted quartic oscillator: classical chaos meets quantum stability

Abstract Out-of-time-ordered-correlators (OTOCs) have been suggested as a means to diagnose chaotic behavior in quantum mechanical systems. Recently, it was found that OTOCs display exponential growth for the inverted quantum harmonic oscillator, mirroring the fact that this system is classically an...
