Semiclassical Analysis

We do a semiclassical analysis for two or three spins which are coupled antiferromagnetically to each other. The semiclassical wave functions transform correctly under permutations of the spins if one takes into account the Wess-Zumino term present in the path integral for spins. The Wess-Zumino term here is a total derivative which has no effect on the energy spectrum. The semiclassical problem is related to that of anyons moving on a sphere with the statistics parameter θ being 2πS for two spins and 3πS for three spins. Finally, we present a novel way of deriving the semiclassical wave functions from the spin wave functions.

Spin Wave Theory

A spin wave theory of magnetic thin films in the HOLSTEIN—PRIMAKOFF approximation is presented which includes cases like SC (100), SC (101), FCC (111), BCC (100) and hexagonal (0001) for any spin S. In the center of interest are the wave functions of the spin waves. Furthermore, a comparison is given with the theories of ABBEL 1 and JELITTO 2, both elaborated for spin S=1/2 and based on another formalism.

Over the past few years, several novel nanoscale computing concepts have been proposed as potential post-complementary metal oxide semiconductor (CMOS) computing fabrics. In these, key focus is on inventing a faster and lower power alternative to conventional metal oxide semiconductor field effect transators. Instead, we propose a fundamental shift in mindset towards more functional building blocks, replacing simple switches with more sophisticated information encoding and computing based on alternate state variables to achieve a significantly more efficient and compact logic. Specifically, we propose wave computation enabled by magnetic spin wave interactions called as spin wave functions (SPWFs). In SPWFs, computation is based on wave interference and information can be encoded in a wave's phase, amplitude and frequency. In this paper, we provide an update on key fabric concepts and design aspects. Our analysis shows that circuit design choices can have a significant impact on overall fabric/device capabilities required and vice versa. Thereby, we adapt an integrated fabric-circuit exploration methodology. Control schemes for wave streaming and synchronization are also discussed with several SPWF circuit topologies. Our estimations show that significant area and power benefits can be expected for SPWF-based designs versus CMOS. In particular, for a 1-bit adder up to 40X area benefit and up to 304X power consumption reduction may be possible with SPWF-based implementation versus 45 nm CMOS.
