Quantum mechanics is considered to be one of the most successful as well as revolutionary theories in the history of physics. It gives the conceptual and mathematical basis of the behavior of matter and energy at atomic and subatomic level. In the course of time quantum mechanics has grown out of a theory that was created to cover experimental anomalies to a comprehensive theory that forms the basis of theoretical physics as known today. Its use is much broader to the early atomic models and now it is central to quantum field theory, particle physics and condensed matter physics, cosmology, and new theories of quantum gravity.
Quantum mechanics has a significant impact on the philosophical concept of physical reality because of its abstract nature, the probabilistic nature of its interpretations, wave functions and non-local correlations. The classical physics, in contrast to quantum mechanics, presupposes the determinism and exact predictability of the phenomena; quantum mechanics regards the unpredictability of phenomena as the natural law. This change of thought has enabled physicists to develop a set of theoretical frameworks, which better capture experimental data, especially at gross extremes of energy and space.
Quantum mechanics is a theory and a method of modern theoretical physics. It allows the development of field theories of the description of fundamental interactions, predicts the occurrence of previously unknown particles, and the explanation of complex collective phenomena in many-body systems. Moreover, additional quantum concepts have already become essential in the study of the early universe, black holes and microphysical geometry of space-time.
The purpose of the research paper is to examine the vast number of theoretical physics studies using quantum mechanics as a tool. The paper has emphasised the contribution of quantum mechanics in the current research on the study of unification of physical theories as it is manifested in key subfields to which quantum mechanics has made contributions. There are also some reflections of where quantum mechanics is likely to make a paradigm shift in the future that confirm its relevance as a fundamental pillar of theoretical physics.
