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

    University essay from Uppsala universitet/Materialteori

    Author : Emil Beiersdorf; [2023]
    Keywords : 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;

    Abstract : 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. READ MORE

  3. 2. Integrability of super spin chains in 6D N=(1,0) SCFTs

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Zuxian He; [2023]
    Keywords : 6D SCFTs; integrability; spin chains; representation theory; symmetry; oscillators; Lie algebra;

    Abstract : Superconformal field theories (SCFTs) are an important class of quantum field theories. These SCFTs have been a significant component in exploring and comprehending the fundamental framework of quantum field theories. READ MORE

  4. 3. Crosscap States in Integrable Spin Chains

    University essay from KTH/Fysik

    Author : Christopher Ekman; [2022]
    Keywords : Theoretical Physics; Mathematical Physics; Integrability; Integrable Systems; Spin chains; Heisenberg model; Integrable Boundary States; Crosscap states; Teoretisk fysik; Matematisk fysik; Integrabilitet; Integrabla system; Spinnkedjor; Heisenbergmodellen; Integrabla gränstillstånd; Crosscaptillstånd;

    Abstract : We consider integrable boundary states in the Heisenberg model. We begin by reviewing the algebraic Bethe Ansatz as well as integrable boundary states in spin chains. Then a new class of integrable states that was introduced last year by Caetano and Komatsu is described and expanded. We call these states the crosscap states. READ MORE

  5. 4. Folding HP Proteins on a Quantum Annealer

    University essay from Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

    Author : Lucas Knuthson; [2022]
    Keywords : Physics and Astronomy;

    Abstract : 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. READ MORE

  6. 5. Exact eigenstates of the Inozemtsev spin chain

    University essay from KTH/Fysik

    Author : Simon Lentz; [2021]
    Keywords : Theoretical physics; Mathematical physics; quantum mechanics; many-body problems; spin chain; Inozemtsev; Calogero-Sutherland; Teoretisk fysik; Matematisk fysik; kvantmekanik; mångpartikel problem; spinnkedjor; Inozemtsev; Calogero-Sutherland;

    Abstract : This thesis deals with the following question: are there more eigenfunctions, other than the already known eigenfunctions, of the spin chain with elliptic interactions known as the Inozemtsev spin chain? The Inozemtsev spin chain interpolates between two quantum integrable spin chains, theHeisenberg spin chain and the Haldane-Shastry spin chain. Therefore it is interesting to explore eigenfunctions of the Inozemtsev spin chain in greater detail. READ MORE
