Special Issue Information

Dear Colleagues,

The fields of fractional-order quantum mechanics and systems combine concepts from fractional calculus into their modeling and design. These projects, focused on non-integer order differentiation and integration of mathematical operations, are discovered across many fields of science and engineering. Concentrating on their incorporation into quantum mechanical and electronic circuits, these ideas are being discovered to design oscillators, circuits, and control systems.

Application of B-poly basis set is used to solve fractional-order differential equations (FDEs) that modeled Schrödinger equation and electric circuits using fractional-order polynomials (α as the fractional-order of polys). The method accomplishes the desired solution in terms of continuous finite number of generalized fractional B-polys in an interval [a, b].

The focus of this research is to advance research on topics relating to the theory, project design, and application of fractional-order quantum systems and circuits. Topics of research include:

  • Fractional order Forced Harmonic Oscillator (FHO);
  • Fractional-order Schrödinger and Dirac equations and prediction of compacted hydrogenic orbitals (so called hydrino particles which may lead to dark matter);
  • Fractional-order quantum mechanical theory, commutators;
  • Exploration of atomic and molecular structure using fractional-order theory;
  • Applications of fractional-order circuit models for energy storage elements, supper capacitors and batteries.

A multivariable technique has been incorporated for guesstimating solutions of Nonlinear Partial Differential Equations (NPDE) using bases set of B-Polynomials (B-polys). To approximate the anticipated solution of the NPD equation, a linear product of variable coefficients ai(t) and Bi(x) B-polys has been employed. Additionally, the variable quantities in the anticipated solution are determined using the Galerkin method for minimizing errors. Before the minimization process is to take place, the NPDE is converted into an operational matrix equation which, when inverted, yields values of the undefined coefficients in the expected solution. The nonlinear terms of the NPDE are combined in the operational matrix equation using the initial guess and iterated until converged values of coefficients are obtained. A valid converged solution of NPDE is established when an appropriate degree of B-poly basis is employed, and the initial conditions are imposed on the operational matrix before the inverse is invoked. However, the accuracy of the solution depends on the number of B-polys of a certain degree expressed in multidimensional variables. Four examples of NPDE have been worked out to show the efficacy and accuracy of the two-dimensional B-poly technique. The estimated solutions of the examples are compared with the known exact solutions and an excellent agreement is found between them. In calculating the solutions of the NPD equations, the currently employed technique provides a higher-order precision compared to the finite difference method. The present technique could be readily extended to solving complex partial differential equations in multivariable problems. Full article
