Abstract
Kekhasan mekanika kuantum ialah, bahwa setiap besaran fisis berupa kuanta, yakni terkuantisasi, dalam artian hanya memiliki nilai disktret tertentu. Melalui relasi E h.v , Bohr dapat menghitung tingkat energi disktret. Selanjutnya Einstein menggunakan hubungan E h.v untuk menjelaskan efek fotolistrik, dan menyimpulkan, bahwa cahaya yang sebelumnya dianggap sebagai gelombang, dapat menunjukkan sifat seperti partikel dan dipancarkan atau diserap hanya dalam kuanta energi. Melalui penjelasan Einstein bahwa foton dapat menunjukkan sifat sebagai materi (partikel), yang menghasilkan persamaan momentum p = h . f / c = h / λ, maka muncul hipotesa de Broglie yang menyatakan bahwa setiap materi juga menunjukkan sifat gelombang. Kemudian untuk menunjukkan dinamika kuantum suatu partikel maupun keadaan dari suatu sistem, diperlukan persamaan matematik yang dikenal dengan fungsi gelombang (
English Abstract
The peculiarity of quantum mechanics is that every physical quantity in the sense that it only has a certain layer value is quantum, ie quantized. Through relationships E h.v , Bohr can calculate the discrete energy level. In addition, Einstein used relationships to explain the photoelectric effect and concluded that light, previously considered a wave, has particle-like properties and can only be emitted or absorbed in energy quanta. Einstein's explanation that photons can show properties as matter (particles) leads to a momentum equation p = h. f / c = h / λ, then the hypothesis of de Broglie appears, which states that each material also shows the wave nature. To represent the quantum dynamics of a particle or the state of a system, a mathematical equation is called a wave function (ψ). The aim of this study is to demonstrate the accuracy and speed of the filtering method to obtain eigenfunction solutions and eigenvalues from quantum potentials, one of which is the Pöschl-Teller potential for bound states. Performed simulation results can show eigenfunctions and eigenvalues for potential Pöschl plates in a bound state that corresponds to the literature.
