  1. 1. Integrability and Thermodynamics of the Gross-Neveu Model

    Master-uppsats, KTH/Fysik

    Författare :Valdemar Melin; [2023]
    Nyckelord :Mathematical Physics; Quantum Field Theory; Bethe Ansatz; Gross-Neveu Model; Matematisk fysik; kvantfältteori; Bethe-ansatsen; Gross-Neveu-modellen;

    Sammanfattning : The Gross-Neveu model is a quantum field theory of interacting N-flavor fermions in 1+1dimensions, with interaction term $(\bar{\psi}_f\psi_f )^2$. This model is studied using the property offactorized scattering. LÄS MER

  3. 2. Quantum signatures in the work fluctuation-dissipation relation protocol

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Matematisk fysik

    Författare :Jian Li; [2023]
    Nyckelord :Quantum entanglement; fluctuation; coherence; quantum information; quantum thermodynamics; Physics and Astronomy;

    Sammanfattning : Quantum thermodynamics deals with the behavior of thermal machines that operate in the quantum regime, where coherences and entanglement can have a significant impact. However, detecting such quantum effects in thermal machines can be challenging, as they are primarily manifested as fluctuations. LÄS MER

  4. 3. Continuous Quantum Control of Quantum Dot Systems

    Master-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Författare :Daniel Holst; [2022]
    Nyckelord :Quantum Control; Quantum Fokker-Planck Master Equation; Maxwell s demon; Quantum dots; Full counting statistics; Generalized Quantum Measurements; Thermodynamics; Physics and Astronomy;

    Sammanfattning : Control and feedback operation of quantum systems have in recent years gained a lot of interest since they are fundamental to achieving functional quantum information processing systems but also of great importance in applications of information to energy conversion within quantum thermodynamics. This thesis has treated a new formalism for feedback control of quantum systems. LÄS MER
