  1. 1. Full Configuration Interaction Model for 1-D Quantum System

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

    Author : Adam Asaad; [2022]
    Keywords : Physics and Astronomy;

    Abstract : The many-body problem is one of the most challenging problems in physics due to the complexity emerging from the interactions of many quantum particles. Since the advent of computers with increasing power, computational methods have been very successful in providing insight and precise solutions to this problem. READ MORE

  2. 2. Energy Landscapes for Early T Cell Development

    University essay from Lunds universitet/Beräkningsbiologi och biologisk fysik

    Author : Yukun Cheng; [2022]
    Keywords : Physics and Astronomy;

    Abstract : T cell lineage development from an early thymic progenitor involves programmed shutoff of progenitor gene expression, upregulation of T cell specification genes, and proliferation. This biological system has been deeply studied and a gene regulatory network (GRN) that can accurately describe the system has been presented. READ MORE

  3. 3. Time-resolved x-ray diffraction study of longitudinal optical phonons in zincblende semiconductors

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Lassi Linnala; [2022]
    Keywords : femtosecond THz radiation; ultrafast x-ray diffraction; pump-probe; longitudinal optical phonons; zincblende semiconductors; anharmonic decay; density functional perturbation theory; Physics and Astronomy;

    Abstract : Anharmonic decay of longitudinal optical (LO) phonons in zincblende semiconductors is not at present well characterized due to the polar and many-body nature of the problem. Femtosecond THz radiation offers a novel route to this study, as the interaction of this radiation is directly with the phonon lattice and these THz excited phonons do not have enough energy to excite electrons over the band gap.

  4. 4. Black Hole Dynamics in Stellar Clusters

    University essay from Lunds universitet/Institutionen för astronomi och teoretisk fysik; Lunds universitet/Astronomi

    Author : Markus Strickert; [2022]
    Keywords : Black Holes; Globular Clusters; Dynamics; Intermediate-mass black holes; Simulations; Physics and Astronomy;

    Abstract : Star clusters can harbour many exotic objects, including black holes (BHs), X-ray binaries and blue straggler stars. In dense stellar environments like globular clusters (GCs), two-body relaxation drives their dynamical evolution, where gravitational interactions between stars strive to equalize their kinetic energy in the cluster.

  5. 5. Quantum Computing in Nuclear Physics

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

    Author : Luca Bernecker; [2022]
    Keywords : quantum computing; nuclear physics; qubits; theoretical physics; Physics and Astronomy;

    Abstract : In this thesis, we investigate many–body systems using simulations of quan- tum computers. Quantum computing is a computational paradigm based on qubits which are defined in a Hilbert space instead of the familiar binary bits. READ MORE
