  1. 1. PVCFA: Principal Variation Context Feature Attribution : Distributed Chess for Perturbation-based Saliency Maps

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Marco Molinari; [2023]
    Keywords : Chess; Perturbation; Saliency maps; Multiagent; Reinforcement Learning; Schack; Perturbation; Saliency maps; Multiagent; Reinforcement Learning;

    Abstract : The research and development field of computer chess improved more in the last 5 years than in the whole history of computers. Unfortunately these unprecedented results comes with techniques that don’t leave much space to intuition and comprehensibility for humans. READ MORE

  3. 2. Generating Perturbative Solutions for Slowly Rotating Perfect Fluids Using the Hartle Scheme

    University essay from Umeå universitet/Institutionen för fysik

    Author : Elin Johansson; [2023]
    Keywords : ;

    Abstract : In this thesis, we study slowly rotating relativistic stars by modeling them as perfect fluids. The Hartle formalism is used to perturb a spherically symmetric static solution into slow rotation and the corresponding field equations to second order are presented. READ MORE

  4. 3. Beyond the Gross-Pitaevskii Equation: A Perturbative Approach

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Teknisk fysik (CI)

    Author : Anton Johansson; [2023]
    Keywords : Gross-Pitaevskii; Beyond mean-field; Many-body Perturbation Theory; Bose-Einstein Condensate; BEC; Physics and Astronomy;

    Abstract : We propose and implement a beyond Gross-Pitaevskii approach based on Many-Body Perturbation theory (MBPT) for the study of Bose-Einstein Condensate (BECs) ground states. Two partitions of the system Hamiltonian are considered. READ MORE

  5. 4. Non-perturbative models of diffractive hadronic collisions

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Edgars Karnickis; [2022]
    Keywords : diffractive process; proton-proton collision; elastic; parton; PDF; saturation; Physics and Astronomy;

    Abstract : In this thesis, a new model for diffractive proton-proton collisions is presented. Interpreting protons as systems of many partons, we treat diffraction in terms of elastic interactions between the partons of the colliding protons. READ MORE

  6. 5. 2d Gauge Theories

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Zhou Zheng; [2022]
    Keywords : ;

    Abstract : The Yang-Mills gauge theories play prominent role in modern high energy physics and the direct non-perturbative calculations present the main challenge in the field.Two dimensional gauge theories provide a nice playground where it is possible to carry out exact computations and at the same time some non-trivial phenomena canbe studied.
