Cognitive load theory is intended to provide instructional strategies derived from experimental, cognitive load effects. Each effect is based on our knowledge of human cognitive architecture, primarily the limited capacity and duration of a human working memory. These limitations are ameliorated by changes in long-term memory associated with learning. Initially, cognitive load theory's view of ...

The author's calculations show that magnetic skyrmions in metallic multilayers such as Co/Pt can be controllably moved on surfaces, simply by using a focused laser beam. Temperature gradients at the spot directly yield skyrmion motion, due to temperature dependence of parameters, but another contribution even more important: Thermoelastic lattice expansion results strain-induced local gradient ...

To enable ultrahigh capacity laser communications in future networks, CONSRT is developing all-optical buffers, high-speed lasers, broadband optical amplifiers and memory devices to replace the speed-limiting optical-electrical-optical (OEO) switching system currently used in optic fiber communication. To date, realization of an all-optical communication network has been stymied by the lack of ...

The specific features including high factor and long vibration lifetime of nanomechanical resonator (NR) in nano-optomechanical systems have stimulated research to realize some optical devices. In this work, we demonstrate theoretically that it is possible to achieve quantum memory for light on demand via a quantum dot system coupled to a nanomechanical resonator. This quantum memory for light ...

All-optical photonic devices are crucial for many important photonic technologies and applications, ranging from optical communication to quantum information processing. Conventional design of all-optical devices is based on photon propagation and interference in real space, which may rely on large numbers of optical elements, and the requirement of precise control makes this approach challengi...
