We welcome you to the conference on Theory of Complex Disorder in Materials in Linköping. 

This A rapid method development is currently taking place within our community allowing the first-principles treatment of materials with complex disorder and excitations.

Example of such cases are magnetic materials above the critical ordering temperature where many-body excitations, magnetic disorder, lattice vibrations and structural defects co-exist. Another case is compositionally complex and high-entropy alloys at elevated temperatures where lattice vibrations and magnetism are coupled to the configurational disorder. A third example is the interaction of configurational, vibrational, and magnetic disorder with spectroscopic, mechanical, piezo- and pyroelectric properties and thermal transport. Yet another developing direction is the usage of many-body techniques for strongly correlated materials together with treatments of vibrational and configurational disorder.

We also want to point towards the emergent usage of machine learning to grasp complex and non-intuitive cases of disordered materials, and to find accurate and efficient models and potentials for e.g. molecular dynamics in presence of disorder.
Method-wise well established approaches like the cluster expansion technique for alloys, phonon calculations for lattice vibrations and disordered local moments for paramagnetism are getting interwoven with techniques such as ab-initio molecular dynamics, atomistic spin dynamics, and dynamical mean-field theory.

Material science questions that have recently been addressed by these methodologies include modeling of the invar effect, magnetism of Fe-Ni under high pressure, anomalous piezoelectric response in Sc-Al-N alloys, magnetolattice coupling in paramagnetic CrN, explanations of vibrational spectra in high-entropy alloys, effects of defects on dislocation core properties, and vibrationally mediated properties in disordered materials.

It is becoming clear that in many cases, the electronic, magnetic, vibrational, and structural degrees of freedom can not be adiabatically decoupled. Many groups are active in these areas and it is timely to arrange a workshop where the different newly developed approaches and their results for specific materials are compared and critically discussed. We foresee that this workshop will serve an important role in keeping this development going and focused on the most promising directions and most relevant areas for the wider community.
