Description
In the field of condensed matter physics, recent research on quantum transport setups has been instrumental in advancing quantum computing and sensing technologies, as well as contributing to theoretical physics. This thesis delves into bias-driven non-equilibrium phase transitions, specifically examining the dynamics and characteristics of these transitions beyond equilibrium scenarios. The focus is on model quantum transport setups with quantum dots, which are nanoscale systems that exhibit quantum phenomena with pronounced clarity. Through the use of Keldysh path integral and stochastic equations, this study establishes a comprehensive theoretical framework for understanding quantum dots in non-equilibrium conditions. Key findings offer fresh insights into the behavior of quantum dots under bias-driven voltage, revealing the interplay between quantum coherence, electron-electron interactions, and environmental coupling.
