Alexander Khitun receives two new grants from NSF and Intel

Dr. Khitun has recently received an NSF award - FET: Small: Magnonic Active Ring Memory and Logic, of $500,000.00 amount for the development of a new type of magnetic memory using spin waves for information read-out. The grant is supported by the CCF Division of the CISE Directorate. Spin waves—or magnons, the quanta of spin waves—represent the excitations of the electron spin subsystem in magnetically ordered media and are observed in ferro- and ferrimagnets, as well as in antiferromagnets. The coherence length of spin waves in ferrite structures may be as large as one centimeter at room temperature allowing us to exploit spin wave interference. The operation of spin wave devices is similar to optical holographic devices that use coherent optical beams for information retrieval. The uniqueness of the spin wave approach is the ability to combine holographic logic units with magnetic memory. This project aims to explore the feasibility of using spin waves for parallel magnetic bit rea-out, investigate device immunity to structure imperfections, study a combination of magnonic and electronic circuits. 

Dr. Khitun has also received an award from Intel Corporation with $435,000.00 amount for the development of Magnonic Active Ring co-Processor for special task data processing. This co-processor is aimed to speed up NP-hard problem solutions (e.g., Prime Factorization, Traveling Salesman problem, The Königsberg bridge problem) by exploiting spin wave superposition. This approach combines the advantages of holographic computing, magnetic data storage, and superposition-based algorithms. The use of built-in memory promises significant power minimization to the level below 1nW per input. These innovative ideas provide us a strong motivation for building a Magnonic co-Processor capable of parallel data processing with ultra-low power consumption.
