  1. 1. Towards a tunable, wide-band acoustic transducer operating in the quantum regime.

    University essay from KTH/Tillämpad fysik

    Author : Abel Hugot; [2022]
    Keywords : Hybrid quantum systems; Acoustics; Impedance matching; SQUIDs; Hybrida kvantsystem; Akustik; Impedansanpassning; SQUIDs.;

    Abstract : In the past decade we have seen fast development of new quantum technologies that promise to revolutionise communications and computing. Many different routes are explored to physically implement such quantum technologies. Among others, we can mention superconducting circuits, spin-based devices and photonic devices. READ MORE

  2. 2. Design and Construction of a Multi-Port Beamsplitter Based on Few-Mode-Fibers

    University essay from Linköpings universitet/Informationskodning

    Author : Daniel Spegel-Lexne; [2022]
    Keywords : beamsplitter; spatial modes; Space division multiplexing; superpositions; LP-modes; few-mode fibers; multi-mode interference; self-imaging; heterogeneous fiber structures; quantum communication; quantum optics;

    Abstract : A MBS (Multi-port beamsplitter) for higher dimensional quantum communication has been designed and constructed and the theory and method for this is presented in this thesis. It uses optical fibers in a heterogeneous structure with a single-mode fiber spliced to a multi-mode fiber and then spliced to a few-mode fiber. READ MORE

  3. 3. Theoretical and experimental investigation of themagneto-optical eect in graphene in the THz region

    University essay from Uppsala universitet/FREIA

    Author : Mircea-George Coman; [2022]
    Keywords : ;

    Abstract : In many optics applications we need lenses with dynamically tunable focal lengths. One design of such a lensis developed in and it relies on the magneto-optical eect. In this design, a graphene layer is placed ina magnetic eld that varies quadratically in space. READ MORE

  4. 4. ELECTRONIC STRUCTURE AND THERMODYNAMIC PROPERTIES OF LI-IONINSERTION IN SULFONAMIDES COMPOUNDS AS ORGANIC HIGH-ENERGY DENSITY CATHODES

    University essay from Uppsala universitet/Materialteori; Uppsala universitet/Kärnfysik

    Author : Mirna Alhanash; [2021]
    Keywords : Organic batteries; computational; DFT; sulfonamides;

    Abstract : The world’s ever-growing energy demand has evoked great interest in exploring renewable energy sources along with sustainable energy storage systems. While inorganic physics of rocking chair mechanism used in Li-ion battery have proven to provide high energy density and high performance, there are problems yet to be overcome in terms of sustainability and recyclability.

  5. 5. Dispersed bio-based binders as drop-in solution for non-woven industry

    University essay from KTH/Fiber- och polymerteknologi

    Author : Emma Ingo; [2021]
    Keywords : Dispersion; Modified Biopolymers; Non-Woven; Binders; Green Chemistry; Dispersion; Modifierade Biopolymerer; Non-Woven; Bindemedel; Grön Kemi;

    Abstract : Sammanfattning på svenska: Målet med projektet var att utveckla ett system av disperserade bindemedel för non-wovenindustrin som inte förutsätter omfattande förändringar i befintliga processer. Bindemedlet ska vara biobaserat, bionedbrytbart och endast bestå av byggstenar som är matkontaktsgodkända av FDA och BFR. READ MORE
