The 2nd International Conference on Complex Orders in Condensed Matter

It is our pleasure to announce ICCOCM 2026, the second International Conference on Complex Orders in Condensed Matter to be held in Evian les Bains, France, from 27 September to 2 October 2026. The conference brings together researchers interested in how complexity in atomic structure—periodic, aperiodic, and disordered—emerges and governs the physical properties of materials. The conference focuses on systems in which long range periodic or aperiodic order, disorder, local structure play a central role in determining electronic, magnetic, dynamical, and functional behavior.

A central goal of the meeting is to bridge communities working on various structurally complex systems, such as aperiodic crystals and their approximant (incommensurately modulated phases, composites and quasicrystals), disordered materials, amorphous materials, high entropy alloys, strongly correlated electrons systems, charge and spin order, superconductivity, magnetically frustrated systems and complex functional materials. Particular attention is given to highlighting the interdisciplinary approach and the common concepts, experimental methods, and theoretical frameworks used across these different fields to understand structural complexity and its influence on physical and chemical properties.
