• TITLE: Coupling Interactions and Trapped Effects for a Triple-Well Potential

  AUTHORS: Sezgin Aydın, Mehmet Şimşek

  KEYWORDS: Perturbation Method, Triple-Well Potential, Duffing Equation, Weak and Strong Couplings.

  ABSTRACT: Weak and strong coupling interactions and trapped effects have always played a significant role in understanding physical and chemical properties of materials. Triple-well anharmonic potential may be modeled for interpretation of energy spectra from the nuclear to macro molecular systems, and also crystalline systems. Exact periods of a trapped particle in each well of the potential are explicitly derived. For the extended Duffing system, it is predicted that infinite series of both frequency and spatial trajectory approach to exact results in the limit of weak-coupling cases (g→0).
