Out-of-time-ordered-correlators for the pure inverted quartic oscillator: classical chaos meets quantum stability
P Romatschke - Journal of High Energy Physics, 2024 - Springer
A bstract 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 …

Quantum information scrambling in two-dimensional Bose–Hubbard lattices
It is a well-understood fact that the transport of excitations throughout a lattice is intimately
governed by the underlying structures. Hence, it is only natural to recognize that the …
