DEPRESSION AND PSYCHOLOGICAL WELL-BEING AMONG PEOPLE HAVING COVID-19 UNDERGONE QUARANTINE

Aims Of Study: Coronavirus is a potentially deadly disease that mostly affects human lung tissue. Multiple cases of unexplained respiratory tract infections were reported to the World Health Organization China in December 2019. The focus of this research was to assess association between depression and PWB in patients who had been isolated due to covid-19. Methodology: A sample of 250 people with covid-19 post quarantine, with age ranges from 25 to 45 were selected by using purposive sampling methods. Depression, anxiety, stress scale and psychological well-being scales were administered. Regression analysis and t-test were employed for statistical analysis. Results: Obtained results evidenced that depression is significantly predict psychological health in the covid-19 population [B= -.015, -.019, F (7.915) sig= .000]. Gender difference is also observed in variable of depression also [(4.78) =.030, p.000]. Limitations and future implications: Future research may base on longitudinal analyses focusing on familial and social factors that may influence the psychological well-being of people living in quarantine. Originality: I certify that the intellectual substance of this article is the result of my own effort and that all assistance and sources used in the preparation of this article have been acknowledged. Conclusion: It was concluded that Depression affects people with COVID-19 and PWB after quarantine. future research may focus more on the influence of the interaction between quarantine and adults’ mental health to fully comprehend the link. 

Analysis of Atomic Coherence Effects in Cavity Quantum Electrodynamical Systems

All counterintuitive and mysterious phenomena exhibited by the quantum theory are linked with the concept of quantum coherence in one way or the other. The best available tool to explicitly explore the in depth meaning of the quantum coherence is to utilize single-particle quantum interference under any preselected experimental scenario. Present thesis employs the themes of Delayed-Choice Quantum Eraser (DCQE) under single and double tag settings as well as the ideology of complementarity tested through Atomic Mach-Zehnder-Bragg interferometer for the purpose. For the DCQE case, our results clearly demonstrate that coherence and hence the interference fringes that get lost due to coupling with the tag ancilla can not only be retrieved back but strangely enough can also be tuned in a delayed-choice manner much later than the due data recording. This delayed-choice adjustability of the fringes shed out many controversies surrounding the quantum eraser along with the conception of the time in the quantum theory, meanings of the state vector reduction, measurement, information and the entropy as well as raises questions about the Ψ- ontic models. The second proposal suggests that quantum coherence apparently seems to lie beyond our classical space-time structure. Whereas the proposal based on atom interferometer with final beam splitter being quantum mechanical i.e. in superposition of being absent and present simultaneously, was used to observe both the wave and particle aspects under a single experimental setting, as suggested recently by Ionicioiu et.al. [Phys. Rev. Lett. 107, 230406 (2011)], and thus questioned the universality of the Bohr''s conjecture. We demonstrated it in a most realistic scenario based on an atomic interferometer with the final beam splitter taken as a high-Q cavity containing the field superposition of zero and one photon. The setup operates through first order off-resonant Atomic Bragg diffraction from the cavity fields with atom''s particle (wave) nature marked through the absence (presence) of a photon in the final cavity and explicitly exhibit wave-particle morphic behavior versus interaction variables. The thesis concludes with demonstration of experimental feasibility of the presented proposals and highlights future directions with a comprehensive philosophical discussion.
