  1. 16. Dynamics for the special class of quantum master equations

    University essay from Linnéuniversitetet/Institutionen för matematik (MA)

    Author : Locatelli Pietro; [2022]
    Keywords : superoperators; density matrices; von Neumann entropy; camel-like entropy; steady states; open quantum systems; dynamical semigroups; decoherence free subspaces;

    Abstract : The paper is an analysis of a special class of the master equations such that the Dissipation superoperator is L(ρ) = [M, [M, ρ]], where M is an hermitian andunitary operator and ρ a density matrix. It mainly investigates the dynamics ofρ and its properties such as boundness of the operators of the master equation,the eigenvalues of these operators, the purity of the states, the steady states.

  3. 17. Black Hole Dynamics in Stellar Clusters

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

    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.

  4. 18. Analysis and modelling of grooming behaviour of mice

    University essay from KTH/Fysik

    Author : Wilhelm Sjöstedt; [2022]
    Keywords : Theoretical physics; Neuroscience; Embedded systems; Complex systems; Teoretisk fysik; Neurovetenskap; Inbyggda system; Komplexa system;

    Abstract : Mapping dynamical motion to neural brain activity is one of many challenges in the field of neuroscience. Further knowledge in this area could provide useful insights in fields such as medical treatment of brain disorders. READ MORE

  5. 19. Investigating Multi-Objective Reinforcement Learning for Combinatorial Optimization and Scheduling Problems : Feature Identification for multi-objective Reinforcement Learning models

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

    Author : Rikard Fridsén Skogsberg; [2022]
    Keywords : Multi-Objective Reinforcement Learning; Radio Resource Scheduling; Deep Q-Networks; Single-policy; Multi-policy; Scalarization.; Flermåls förstärkningsinlärning; Radio resurs schemaläggning; Djupa Q-nätverk; Enskilt mål; Flermål;

    Abstract : Reinforcement Learning (RL) has in recent years become a core method for sequential decision making in complex dynamical systems, being of great interest to support improvements in scheduling problems. This could prove important to areas in the newer generation of cellular networks. READ MORE

  6. 20. Turing's model for pattern formation

    University essay from KTH/Fysik

    Author : Oskar Forsström; Oskar Falgén Nikula; [2022]
    Keywords : Reaction-diffusion; Turing pattern; morphogen; Grier-Meinhardt; Schnakenberg; numerical analysis; minimum energy control;

    Abstract : In an attempt to describe how patterns emerge in biological systems, Alan Turing proposed a mathematical model encapsulating the properties of such processes. It details a partial differential equation governing the dynamics of two or more substances, called morphogens, reacting and diffusing in a specific manner, in turn generating what has now come to be denoted as Turing patterns.
