Göran Lindblad’s foundational contributions have laid the groundwork for a deeper understanding of quantum open systems, particularly through the formalism of Markovian Master Equations known as the Lindblad or Gorini-Kossakowski-Sudarshan (GKS) equations. These equations provide a robust framework for describing the dynamics of quantum systems that interact with their environment, allowing for an exploration of non-equilibrium thermodynamics in the quantum regime One significant application of the Lindblad formalism is in the study of laser systems, where quantum open system dynamics can reveal intriguing thermodynamic properties. Lasers, as coherent light sources, are quintessential examples of systems where quantum effects and thermodynamic processes converge. By utilizing the properties of quantum relative entropy, a fundamental concept introduced by Lindblad, researchers can assess the information dynamics and thermodynamic quantities associated with laser operation. This interplay between quantum thermodynamics and laser models not only deepens our understanding of these devices but also opens up new avenues for research in quantum technologies and beyond. Through the lens of Lindblad’s contributions, this thesis aims to present selected results in Quantum Thermodynamics, focusing on the implications of the Lindblad Master Equations in the context of laser physics. By examining these results, we underscore the significance of Lindblad's work particularly via quantum relative entropy in shaping contemporary research in quantum mechanics and its applications.
