  2. 1. Dispersion Engineering : Negative Refraction and Designed Surface Plasmons in Periodic Structures

    Author : Zhichao Ruan; Min Qiu; Henri Benisty; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; photonic crystal; dispersion property; negative refraction; surface plasmon polariton; designed surface plasmon; negative index material; layer-KKR method; finite-difference time-domain method; plane wave method; subwavelength imaging; open cavity; enhanced transmission; slowing light; Photonics; Fotonik;

    Abstract : The dispersion property of periodic structures is a hot research topic in the last decade. By exploiting dispersion properties, one can manipulate the propagation of electromagnetic waves, and produce effects that do not exist in conventional materials. READ MORE

  4. 2. Experimental investigations of some time-dependent phenomena in the slowing down and diffusion of neutrons

    Author : Gudmar Grosshög; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

  5. 3. Towards a Circular Economy with Environmental Product Policy : Considering dynamics in closing and slowing material loops for lighting products

    Author : Jessika Luth Richter; Internationella miljöinstitutet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; extended producer responsibility; Circular Economy; critical materials; Policy Evaluation; product lifetime; lamps; lighting products; WEEE; Product Policy; ecodesign;

    Abstract : A Circular Economy (CE) can help to achieve the sustainable development goal of responsible consumption and production. Product policies, in turn, can support CE objectives by promoting reuse of products, recycling of materials, and providing ecodesign incentives for more durable products. READ MORE

  6. 4. Cognitive control in reinforcement learning : brain structure and function

    Author : Björn C Schiffler; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Adapting behaviour according to internal or external feedback is a fundamental property of cognitive control. For example, humans tend to slow down when they make mistakes, a process called post-error slowing (PES), which has previously received extensive attention in research on response inhibition.

  7. 5. Dynamics of complex magnetic systems

    Author : Kristian Jonason; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; Solid State Physics; fasta tillståndets fysik;

    Abstract : Dynamic magnetic properties of disordered and frustrated magnetic systems have beenexperimentally investigated utilising SQUID (Superconducting Quantum Interference Device)magnetometry. The studied systems are spin glasses, reentrant ferromagnets, reentrantantiferromagnets and diluted Ising antiferromagnets. READ MORE
