THE GENERALIZED OTOC FROM SUPERSYMMETRIC QUANTUM MECHANICS: Study of Random Fluctuations from Eigenstate Representation of Correlation Functions
The concept of out-of-time-ordered correlation (OTOC) function is treated as a very strong theoretical probe of quantum randomness, using which one can study both chaotic and non-chaotic phenomena in
Dynamics of quantum information scrambling under decoherence effects measured via active spin clusters
Developing quantum technologies requires the control and understanding of the non-equilibrium dynamics of quantum information in many-body systems. Local information propagates in the system by
Complexity from the reduced density matrix: a new diagnostic for chaos
TLDR
It is demonstrated that the evolution of complexity is a possible diagnostic of chaos through explicit calculations on a toy model of two coupled harmonic oscillators, where one or both of the oscillators are inverted.
Classical and quantum chaos in chirally-driven, dissipative Bose-Hubbard systems
We study the dissipative Bose-Hubbard model on a small ring of sites in the presence of a chiral drive and explore its long-time dynamical structure using the mean-field equations and by simulating
Entanglement Phase Transitions in Measurement-Only Dynamics
Unitary circuits subject to repeated projective measurements can undergo an entanglement transition as a function of the measurement rate. This transition is generally understood in terms of a
Information Scrambling and Loschmidt Echo.
TLDR
Analytically and numerically, the out-of-time order correlator is demonstrated to be given by the thermal average of Loschmidt echo signals, a well-appreciated familiar diagnostic that captures the dynamical aspect of chaotic behavior in the time domain and is accessible to experimental studies.
Out-of-time-order correlations in the quasiperiodic Aubry-André model
We study out-of-time-ordered correlators (OTOC) in a free fermionic model with a quasiperiodic potential. This model is equivalent to the Aubry-Andr\'e model and features a phase transition from an
Out-of-time-order correlator in weakly perturbed integrable systems
Classical quasi-integrable systems are known to have Lyapunov times much shorter than their ergodicity time, but the situation for their quantum counterparts is less well understood. As a first
Quasi-integrable systems are slow to thermalize but may be good scramblers.
TLDR
The quantum Lyapunov exponent, defined by the evolution of the four-point out-of-time-order correlator (OTOC), of integrable systems which are weakly perturbed by an external noise is examined, a setting that has proven to be illuminating in the classical case.
Scaling at the OTOC Wavefront: Integrable versus chaotic models
Out of time ordered correlators (OTOCs) are useful tools for investigating foundational questions such as thermalization in closed quantum systems because they can potentially distinguish between

Out-of-time-order fluctuation-dissipation theorem.
TLDR
A generalized fluctuation-dissipation theorem is proved for a certain class of out-of-time-ordered correlators (OTOCs) with a modified statistical average, which are bipartite OTOCs for general quantum systems in thermal equilibrium and it is shown that the theorem can be generalized to higher-order n-partite OT OCs as well as in the form of generalized covariance.

TLDR
It is formally demonstrated that the multiple-quantum coherence spectra, a specific family of OTOCs well known in NMR, can be used as an entanglement witness and as a direct probe of multiparticle entanglements.
