Abstract |
This thesis explores aspects on two broad parts of the field of quantum system dynamics, namely, the strong interaction between matter and stochastically fluctuating
radiation and the dynamics of open quantum systems. In the first topic, we investigate atomic transitions under strong driving using squeezed radiation, which is
known to exhibit photon super-bunching properties and explore its effects on double
optical resonance (DOR) in pump and probe setups. Additionally, we study the phenomenon of electron-positron pair creation in presence of stochastic radiation and
explore the possibility of observing a non-linear enhancement of the process in the
multi-photon regime due to photon correlation effects of the radiation. In the second
topic, we analyze various aspects, including qubit correlations in non-Markovian
environments, fidelity of quantum state transfer in the presence of non-Markovian
dissipation, new methods of quantitatively evaluating non-Markovianity in open
quantum systems, the relationship between the Quantum Zeno effect and exceptional points in non-Markovian open quantum systems, as well as the phenomenon
of single-resonance autoionization viewed from the perspective of non-Hermitian
physics. This thesis contributes to our understanding of strong driving effects and
the dynamics of open quantum systems, shedding light on fundamental quantum
phenomena and paving the way for future advancements in intriguing areas of active research.
