Agop, C.Gh. Buzea, S. Bacaita, A. Stroe and M. Popa ContentsVIII Preface It can be stated that one of the greatest creations of twentieth century physics has been quan‐ tum mechanics. This has brought with it a revolutionary view of the physical world in its wake initiated by the work of people like Bohr, Schrödinger, Heisenberg and Born, Pauli and Dirac and many others. The development of quantum mechanics has taken physics in a vastly new direction from that of classical physics from the very start. This is clear from the compli‐ cated mathematical formalism of quantum mechanics and the intrinsic statistical nature of measurement theory. In fact, there continue at present to be many developments in the subject of a very fundamental nature, such as implications for the foundations of physics, physics of entanglement, geometric phases, gravity and cosmology and elementary particles as well. Quantum mechanics has had a great impact on technology and in applications to other fields such as chemistry and biology. The intention of the papers in this volume is to give research‐ ers in quantum mechanics, mathematical physics and mathematics an overview and introduc‐ tion to some of the topics which are of current interest in this area. Of the 29 chapters, the range of topics to be presented is limited to discussions on the founda‐ tions of quantum mechanics, the Schrödinger equation and quantum physics, the relationship of the classical-quantum correspondence, the impact of the path integral concept on quantum mechanics, perturbation theory, quantization and finally some informational-entropy aspects and application to biophysics. Many of the papers could be placed into more than one of these sections, so their breadth is quite substantial. The book has been put together by a large international group of invited authors and it is neces‐ sary to thank them for their hard work and contributions to the book. I gratefully acknowledge with thanks to the assistance provided by Ms. Danijela Duric who was publishing manager dur‐ ing the publishing process, and Intech publishing group for the publication of the book.

Concluding remarks Once that we have made use of the same concepts in both classical and quantum mechanics, it is more easy to understand quantum theory since many objects then are present in both theories Actually, there are many things in common for both classical and quantum systems, as is the case of the eigensurfaces and the eigenfunctions of conjugate variables, which can be used as coordinates... densities [1] and other define functions of two variables from single variable quantum wave functions [2,3] Our approach is to use the same concepts in both types of dynamics but in their own realms, not using foreign unnatural objects In this chapter, we derive many inter relationships be‐ tween conjugate variables 1.1 Conjugate variables An important object in Quantum Mechanics is the eigenfunctions... 24 2 Advances in Quantum Mechanics Advances in Quantum Mechanics which indicates remnants of tori (cantori) in the classical phase space [9] Thus, over two decades from the early 70th, AKP was a good testing ground of theories (along with billiards) as well as a constant source of important information to quantum chaos studies However, there has not been much recent theory investigation on AKP Especially,...
