We present an algebraic approach for finding exact solutions of the wave equation. The approach, which is referred to as the Tridiagonal Representation Approach (TRA), is inspired by the J-matrix method and based on the theory of orthogonal polynomials. The class of exactly solvable problems in this approach is larger than the conventional class. All properties of the physical system (energy spectrum of the bound states, phase shift of the scattering states, energy density of states, etc.) are…

The energy spectrum of a new exponentially confining potential
In this work, we consider a general Morse-type confining potential that was introduced recently by Alhaidari (J Theor Math Phys 205, 2020. arXiv:2005.09080 ). This potential is completely confining
Solving Schrödinger equation by mapping it into a Heun-type equation with known solutions
We transform the Schrodinger wave equation into a nine-parameter Heun-type differential equation. Using our solutions of the latter in the work of Alhaidari [J. Math. Phys. 59, 113507 (2018)], we are

Quantum mechanics without potential function
In the standard formulation of quantum mechanics, one starts by proposing a potential function that models the physical system. The potential is then inserted into the Schrodinger equation, which is
