Probing Complex Quantum Dynamics through
Out-of-time-ordered Correlators

Moved from 2020 to 2021 due to covid-19


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 as a privileged tool. 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.

Topics include

  • Out-of-time-ordered correlators (OTOCs) 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
  • OTOCs as tools to differentiate many-body and few-body quantum chaos
  • 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
