ABSTRACT
The nonlinear physics of many-particle system is perhaps one of the most difficult problems and will remain so for a long time to come. As such, it yields fascinating physics with rich phenomena, challenging to theoretical interpretations. The nonlinear interaction between the heterogeneous junction and the perfect conducting leads will be essential. The understanding of basic transport in the molecular construct has slowly but surely progressed. The correlation and coherence effect plays an important role in the many-body interactions. There are important distinctions between correlation and coherence. When an electrical signal suddenly changes, a nano device would take time to relax back to an equilibrium state. This implies an inductance effect. Nanoscience deals with the construct of molecular precision. Great accuracy in calculating the molecular structure is required in the design of a molecular device. The carbon nano tube was assembled into a ring oscillator.
