  1. 1. Spin-Glass Behaviour in Ordered Solids

    Kandidat-uppsats, Uppsala universitet/Materialteori

    Författare :Erik Karpelin; [2023]
    Nyckelord :spin-glass; self-induced; variation; Edwards-Andersson; glassy;

    Sammanfattning : The spin-glass is a peculiar magnetic phase, exhibiting non-trivial dynamics at low temperatures, characterized by an continuously evolving state without long-range order. The behavior requires some degree of disorder to occur, often in the way of impurities or random exchange energy between the spins. LÄS MER

  3. 2. Användning av svensk ull i möbeltyger

    Kandidat-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Hedvig Nygren; Agnes Paterson Flisberg; [2023]
    Nyckelord :Swedish wool; coarse wool; woven upholstery fabric; textile value chain; sustainability; circularity; fiber characterization; quality testing.; Svensk ull; grov ull; vävda möbeltyger; textil värdekedja; hållbarhet; cirkularitet; fiberkarakterisering; kvalitetstestning.;

    Sammanfattning : Syntetiska material står idag för merparten av produktionskedjan för textilmaterial globalt. Behovet av biobaserade regenererade fibrer ligger i framkant när det gäller framtida val för produktion av textilmaterial i samband med målen för hållbar utveckling. LÄS MER

  4. 3. Creating Artificial Quantum Chiral States : Time Evolving Open Spin Chains

    Kandidat-uppsats, Uppsala universitet/Materialteori

    Författare :Emil Beiersdorf; [2023]
    Nyckelord :Quantum chirality; chirality; spin interaction; Heisenberg interaction; DM interaction; quantum physics; quantum mechanics; molecular nanomagnet; mathematical physics; theoretical physics; Kvantkiralitet; kiralitet; spinninteraktioner; Heisenberginteraktion; DMinteraktion; kvantfysik; kvantmekanik; molekylär nanomagnet; matematisk fysik; teoretisk fysik;

    Sammanfattning : The discoveries in applications of chirality in various areas of science seem to never cease to emerge. Chirality, being the property that some objects are geometrically distinguishable from their mirror image, is a tiny difference of vast importance. LÄS MER

  5. 4. Classical motion in synthetic monopole fields

    Kandidat-uppsats, Uppsala universitet/Materialteori

    Författare :Ola Carlsson; [2022]
    Nyckelord :;

    Sammanfattning : In the Born-Oppenheimer approximation for a quantum system the emergent synthetic magnetic field can be seen as generated by monopoles at points of degeneracy, in full analogue to the synthetic fields generating the geometric phase of adiabatically evolving quantum systems. The plausibility of using these synthetic magnetic monopoles as a means to study magnetic monopole dynamics in the absence of fundamental magnetic monopoles has been explored. LÄS MER

  7. 5. Folding HP Proteins on a Quantum Annealer

    Master-uppsats, Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

    Författare :Lucas Knuthson; [2022]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Quantum annealing provides a promising avenue for obtaining good approximate solutions to difficult optimization problems. Protein folding represents one such problem. For testing novel algorithms and technologies, simplified lattice models are well suited, as they represent considerable computational challenges despite their simplicity. LÄS MER
