Probing Complex Quantum Dynamics through
Out-of-time-ordered Correlators
International Workshop
11 - 15 October 2021
Scrambling, loss and possible retrieval of quantum information in many-body systems are important concepts presently studied in various setups. The workshop will discuss progress and future directions in the inter-related fields of information scrambling, complex quantum dynamics, chaos and criticality, by focusing on out-of-time-ordered correlators and related tools. Quantifying the time-growth of operators provides a unifying paradigm that favors the convergence of different physics communities to be represented at the workshop, comprising both theory and experiment. After a long period, we plan to resume the incomparable face-to-face exchange of scientific ideas and results at the MPI-PKS, but we will also offer virtual participation.
Topics include
- Out-of-time-ordered correlators (OTOCs), spectral form factors, and related tools, as indicators for various types of quantum many-body dynamics
- Relation of OTOCs to other measures of (in)stability and complexity growth
- Experiments and experimental protocols
- Generality of the bounds on chaos
- Probing quantum chaos and holography
- Semiclassical approaches to OTOCs
- OTOCs, entanglement and quantum thermodynamics
- OTOCs and the eigenstate thermalization hypothesis
- Dynamical quantum phase transitions and many-body chaos near phase transitions
We plan for a hybrid workshop with a number of participants on-site and the others connected via video conference.
For accepted participants, online attendance will be possible in any case. The organizers will decide and inform about an option of on-site attendance at a later stage.
