This Thursday, 02.12 at 11.00 am we will have a FH seminar where Prof. Yair Shokef from Tel Aviv University will give a lecture titled "Effective Magnetism in Mechanical Metamaterials: from Spin Glass to Spin Ice". See the details in the file attached.
Metamaterials are artificial structures made of arrays of multiple building blocks of
mesoscopic length scales. For many mechanical metamaterials, the possible geometric states
of each building block may be linked to discrete spin states of a magnetic system. I will show
how designing the building blocks and their mutual spatial arrangement in a metamaterial
enables much flexibility in setting the interactions in the corresponding spin system. This
control of the frustration and the topological features of the spin system leads to novel
functionalities such as response to predefined mechanical textures, spatial steering of stress
and deformation fields, and multiple coexisting steady states.
