  1. 1. Exploring time-extended complexity measures in magnetic systems

    University essay from Uppsala universitet/Materialteori

    Author : Jannes van Poppelen; [2023]
    Keywords : ;

    Abstract : Complexity, a fundamental concept in physics, encompasses phenomena spanning atomic to cosmic scales. The natural emergence of complexity can be explained by self-organized criticality. In this work, two complexity measures in magnetic systems are explored. READ MORE

  2. 2. Spin correlations in top quark pair production at the Large Hadron Collider

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Simon Ahlstedt; [2022]
    Keywords : Top quarks; Top quark pair production; LHC; Spin correlations; MadGraph5_aMC@NLO; Dilepton decay channel; Leading order; Interference effects; Event generation.; Physics and Astronomy;

    Abstract : In this work we investigate the spin correlation effect of the interference between signal and irreducible background events present in top quark pair production at the LHC at LO in the dilepton channel. To simulate the high energy proton-proton collisions of the LHC, MadGraph5_aMC@NLO framework is used as an event generator. READ MORE

  3. 3. Real-time Entanglement of Auger and XPS-electrons: a preliminary investigation

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Philip Johansson; [2019]
    Keywords : Entanglement; Auger; Auger decay; photoemission; XPS; ED; exact diagonalization; Physics and Astronomy;

    Abstract : In this work, we employ a semi-classical approach to light matter interaction to describe and char- acterize spin configurations resulting from quantum correlations between electrons created by a photoemission event and by the following Auger decay. The system studied consists of three atomic levels and two continua. READ MORE

  4. 4. Testing Direct Coupling Analysis on HP Model Proteins

    University essay from Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Author : Mustafa Kadhim; [2018]
    Keywords : Direct Coupling Analysis HP model proteins; Physics and Astronomy;

    Abstract : Direct coupling analysis (DCA) models correlations in sets of related (homologous) protein sequences using a Potts-like spin model ansatz. From the couplings of the Potts model, derived by inverse statistical mechanics, residue-pair contacts in the 3D structure of the protein are predicted. READ MORE

  5. 5. Thermopower simulation of a two level spinless quantum dot

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Matematisk fysik

    Author : Susanna Hammarberg; [2014]
    Keywords : quantum dot transport thermopower; Physics and Astronomy;

    Abstract : Quantum dots are interesting candidates for a broad variety of electronic components, with single electron transistors and LEDs being two examples already well on their way. In nanostructures, such as quantum dots, quantum effects greatly influence the transport. READ MORE
