    Abstract : The demand and consumption of energy is increasing dramatically all around the world. Broad adoption of fossil fuels has triggered an enormous threat to the environment. To ensure sustainability of our species and habitat, new solutions to fulfill the energy demand have to be found. READ MORE

  4. 7. Near-Field Radiative Heat Transfer between Plasmonic Nanostructures

    Author : Jin Dai; Min Yan; Philippe Ben-Abdallah; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fysik; Physics; Energy Technology; Energiteknik;

    Abstract : Radiative heat transfer (RHT) due to coupled electromagnetic near field scan significantly exceed that dictated by Planck’s law. Understanding such phenomenon is not only of fundamental scientific interest, but also relevant to a broad range of applications especially connected to nanotechnologies. READ MORE

  5. 8. Confinement Sensitivity in Quantum Dot Spin Relaxation

    Author : Carl Wesslén; Eva Lindroth; Andrei Manolescu; Stockholms universitet; []

    Abstract : Quantum dots, also known as artificial atoms, are created by tightly confining electrons, and thereby quantizing their energies. They are important components in the emerging fields of nanotechnology where their potential uses vary from dyes to quantum computing qubits. Interesting properties to investigate are e.g. READ MORE

  6. 9. Growth and Characterization of ZnO Nanocrystals

    Author : Leif KE Ericsson; Kjell O Magnusson; Lars SO Johansson; Hanmin M Zhang; Omer Nour; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; ZnO; Nanocrystals; Surface physics; XPS; SEM; AES; AFM; STM; Physics; Fysik;

    Abstract : The understanding of surfaces of materials is of crucial importance to all of us. Considering nanocrystals (NCs), that have a large surface to bulk ratio, the surfaces become even more important. Therefore, it is important to understand the fundamental surface properties in order to use NCs efficiently in applications. READ MORE

  7. 10. Quantum Optics and Waveguide Quantum Electrodynamics in Superconducting Circuits

    Author : Emely Wiegand; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Quantum Optics; Circuit Quantum Electrodynamics; Waveguide Quantum Electrodynamics; Superconducting Qubits; Artificial Atoms;

    Abstract : Waveguide circuit quantum electrodynamics (waveguide circuit QED) studies light-matter interaction with superconducting circuits in one dimension. In circuit QED, natural atoms are replaced by superconducting qubits consisting of a non-linear Josephson junction, resulting in an anharmonic energy spectrum just like real atoms. READ MORE
