    Abstract : Entanglement is a fundamental aspect of quantum computation and quantum information processes. In this work, we analyse the entanglement of two microwave resonators when connected to a semiconductor double quantum dot. READ MORE

  3. 2. Hydrogen Absorption in Metal Hydrides : Transmission of light in relation to hydrogen concentration and site occupancy of ultrathin vanadium films

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : David Sörme; [2022]
    Keywords : metal hydrides; iron-vanadium superlattice; hydrogen; hydrogen site occupancy; hydrogen concentrationm; hydrogen storage;

    Abstract : In this study the effect of hydrogenation on the optical properties in the wavelength range 400-1023 nm of an ultrathin iron-vanadium superlattice is investigated. Specifically, mea- surements of transmission are performed under different states of hydrogenation, along with measurements of absolute hydrogen concentration and hydrogen site occupancy. READ MORE

  4. 3. Geometry Dependent Optimal Bounds of Absorption and Scattering Cross-section for Small Nanoparticles

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Md Shabbir Hossain Khan; [2022]
    Keywords : Scattering; Absorption; Nanoparticle; Cross-section; Mie; Electromagnetic; FDTD; dipole; Wavenumber.;

    Abstract : Light-matter interaction in particles of subwavelength size mostly depends on the size, shape, composition of the particles and relies on the properties of incident light. Henceforth, resonant behavior of light can be effectively controlled by changing the aforesaid geometrical parameters. READ MORE

  5. 4. Optical Study of Micro-Resonators with G-centers as an Active Medium

    University essay from KTH/Tillämpad fysik
