  Description:

Venue

Nordita, Stockholm, Sweden

Scope

  • Entangled and competing orders
  • Dynamic multiferroicity and coupled critical points
  • Dynamic orders and time orders
  • Transient dynamics and correlations
  • Dynamics of hidden orders
  • Discoveries of classical active matter
  • Dynamics of classical and quantum fluids
  • Hidden and odd frequency orders

Over the past century, the starting points in nearly any new study of condensed matter have been Fermi liquid theory and the associated Landau-Ginzburg-Wilson approach to phase transitions, supplemented with important concepts including localization and classification according to symmetry. These ideas are based on the fundamental notion of an ordered state characterized by a Landau order parameter and the emergence of quasiparticles corresponding to the broken symmetry that can often be approximated as non-interacting. This paradigm has been remarkably successful, with the most prominent example being the BCS theory of superconductivity and a Fermi liquid theory.

The conventional approaches for treating condensed matter described above have therefore been challenged recently. We see a growing library of states that do not display classic Fermi liquid behavior or conventional Landau orders, e.g., topological and non-local orders that go beyond the Landau-Ginzburg-Wilson approach. We also witness discoveries of many materials that exist on the verge of transitions to different types of ordered states. As a result, the conventional notion of well-defined quasiparticles no longer applies.

These developments are encapsulated within the new category of condensed matter known as “quantum materials”, which has stimulated a host of new ideas based on unconventional correlated, entangled, and topological orders. Importantly, entangled orders, where the description of one order is incomplete without specifying its entangled counterpart, are purely quantum in nature and thus inherent to these materials. These materials have been challenging to understand and model with traditional approaches, but also offer great potential for new functionalities (e.g., using multiferroic materials) tuned by varying external conditions (e.g., temperature and doping). Microscopic features (e.g., correlations, entanglement, novel orders in time domain like odd frequency superconductivity and topology) that determine the properties of quantum materials naturally reveal themselves in the time domain, since their temporal evolution is governed by the full Hamiltonian, which contains interactions. These interactions determine transient correlations and coherences in quantum materials.

Attendant with the developments on theory and modeling we see a rapid rise of new probes of matter, most prominently, MAX IV and ESS that are capable of revealing a new and exciting behavior of quantum matter at the short time scale with high spatial resolution.

In a broader context, similar developments impact research on classical matter. To stimulate the exchange of ideas between classical and quantum matter research we will also have a lecture on the dynamic classical matter.

The workshop is coordinated with the KTH Materials Dialogue Day which is an annual event for materials related research at KTH Royal Institute of Technology. The 2018 Materials Dialogue Day takes place December 13 and is on the topic Quantum Materials.
