Description
The workshop aims at reviewing the state-of-the-art in non-equilibrium systems affected by (quantum) fluctuations and decoherence mechanisms bringing together scholars of international calibre active in diverse research communities, such as condensed matter, linear and non-linear optics, cold atoms and quantum information.

The workshop aims at reviewing the state-of-the-art and propose developments in the theoretical description and experimental control of decoherence and fluctuations in an ample set of physical contexts. One of the aims of the workshop is to identify similarities and differences between decoherence in model systems, such as optomechanical cavities and open quantum systems, and non-equilibrium phenomena in complex materials.
The goal is to set the roadmap to develop a universal view on how decoherence processes and quantum fluctuations govern the non-equilibrium dynamics in different systems.

Topics:
 
  • Quantum materials
  • Open quantum systems
  • Non equilibrium quantum systems and processes
  • Optomechanical systems
  • Decoherence
  • Cold Atoms

Contributed talks:
Limited space for contributing talks is available.

Poster session:
A poster session will be organized.

Grants:

A limited number of grants are available to support the attendance of selected participants, with priority given to participants from developing countries. There is no registration fee.

      • 09:20 Order parameter recovery dynamics in pump and probe experiments 40' 
        One of the central challenges of ultrafast experiments is understanding order parameter recovery dynamics following a quench induced by the pump pulse. I will present theoretical analysis of this problem using large-N effective model of overdamped dynamics. Interesting features of this model include strong dependence of the recovery time on the strength of the pump pulse and different relaxation timescales for excitations at different lengthscales. Similar features have been observed in systems with different types of order, including CDW order in LaTe3 and AF order in Sr2Ir2O4. I discuss other predictions of the model that can be tested experimentally, including over-population of low momentum modes and emergent universal scaling form of transient correlation functions.
