Progress to Opto-Spintronics

Researchers from Sweden, Finland and Japan have now constructed a semiconductor component in which information can be efficiently exchanged between electron spin and light – at room temperature and above. Semiconductor spintronics have potential for opto-spintronics, which will allow integration of spin-based information processing/storage with photon-based information transfer/communications. Unfortunately, progress has so far been severely …

Casimir effect theoretically could stabilize and manipulate higher dimensions for warp drive

Arxiv – the Casimir e ffect may serve as a mechanism to mediate higher dimensional stability, and also as a possible mechanism for creating a small but non-zero vacuum energy density. Chapters of 120 page dissertation on Casimir effect 1. we review the nature of the quantum vacuum and discuss the diff erent contributions to …
