Symposium QM02-Functional Ferroic Materials for Unconventional Computing

Ferroic materials with spontaneous magnetic or electric long-range order are a rich source for emergent functional phenomena, enabling conceptually new pathways towards unconventional computing. The dynamical properties of spin- and dipole-systems displaying frustration or competing interactions, for example, can be utilized for the implementation of reservoir computing. Furthermore, tunnel junctions with ferroelectric barriers allow continuous conductivity changes that can be leveraged for multilevel data storage in memristor chips, whereas magnetic tunnel junctions behave as oscillators, to be used as artificial synapsis and neuron devices for neuromorphic computing. Recently, topological solitons have moved into focus, adding a strong cross-disciplinary dimension to the field, connecting the ferroelectrics and the magnetism communities. Innovative device concepts based on magnetic materials and ferroelectrics, as well as overarching theoretical descriptions, are now being investigated and combined to develop a joint fundamental understanding, propelled by the recent developments in theory, synthesis and characterization.

This symposium aims to bring together scientific experts and young scientists with an interest in ferroic materials (ferroelectric, ferromagnetic, and multiferroic), topological phenomena and innovative technologies, fostering interactions and advancing knowledge of emergent functional properties and related hardware concepts for unconventional computing.
