5) Abstract
   - Magnons, the quantum-mechanical excitations of spin waves, are bosons whose number does not need to be conserved in scattering events. The field of magnonics aims to manipulate the properties of these fundamental magnetic excitations for practical applications. Information transfer and processing based on magnons do not suffer from Joule heating. Hence, magnonics may lead to alternative information technologies with lower power consumption that meet the demands for a carbon-neutral future. Strongly interacting artificial spin systems are magnetic metamaterials where magnetic domains can be mapped onto a spin-lattice model. These systems have emerged as functional material platforms for reconfigurable magnonics, including two-dimensional magnonic crystals, in which the desired magnon band structure is engineered, similar to the approach taken in photonics. Here, I will discuss how the complex behavior of magnons in strongly-interacting nanomagnetic arrays can be manipulated through an interplay between material properties, the geometrical arrangement of patterned ferromagnetic nanostructures, and the reconfigurability of their magnetization state. 
 
6) Biosketch

   - M. Benjamin Jungfleisch is an Assistant Professor at the University of Delaware in the Department of Physics and Astronomy. His research interest is in a wide range of magnetism-related effects focusing on spin-transport phenomena and spin dynamics in nanostructures. He received the Department of Energy Early Career Research Award in 2019 and the National Science Foundation EPSCoR RII Track-4 Fellowship in 2018. Before joining the University of Delaware, he was a postdoctoral researcher at Argonne National Laboratory within the Materials Science Division. He received his Ph.D. in Physics at the University of Kaiserslautern in 2013 and an M.S. in Physics in 2009 from the same institution.
