Abstract
This dissertation explores the non-equilibrium thermodynamics of quantum systems, specifically focusing on spin-1 nuclei and the dual influences of external perturbations and quadrupolar interactions. We first analyze the dynamic responses of these nuclei to external perturbations, utilizing principles from quantum and statistical mechanics. By manipulating a work parameter and treating work as a random variable, we collect data from finite-duration cyclic processes to compute the generated work distribution. We then extend our investigation to the contributions of quadrupolar interactions, comparing their effects with those of external perturbations. Through this comprehensive analysis, we derive key equilibrium quantities, such as the free energy difference between initial and final states, while deepening our understanding of work distribution properties. Overall, this research enhances our insights into the complex dynamics of non-equilibrium quantum thermodynamics and sets the stage for future explorations of quantum systems under varying conditions.
