The Generalized Dirac Oscillator in Doubly Special Relativity: A Complexified Morse Interaction

Abstract We study the one-dimensional generalized Dirac oscillator with a complex Morse interaction, f(x) = D − qe−αx, in the Magueijo–Smolin (MS) and Amelino-Camelia (AC) realizations of doubly special relativity (DSR). The spatial problem factorizes into supersymmetric partners...

New class of integrable systems: the recurrence coefficients of 2-orthogonal polynomials

We solve the system governing the recurrence coefficients of 2-orthogonal polynomials.

Fuzzy logic-based diagnosis of inverter switch faults in VSI-Fed induction motors

This paper presents a fuzzy logic-based diagnostic method for detecting and identifying faults in power switches of Voltage Source Inverters (VSIs) feeding induction motors. Problem. Conventional diagnostic techniques often require additional sensors or sophisticated hardware, wh...

Synergistic EMHD control and multi-objective optimization of ternary hybrid nanofluid flowing over radiatively active porous panel

Magnetohydrodynamic flows of ternary hybrid nanofluids have attracted considerable attention owing to their promising applications in advanced thermal management and next-generation high-power electronics cooling. However, despite their superior thermophysical properties, most ex...

Analytical and Numerical Bound-State Analysis of One-Dimensional Time-like Vector Potentials in the Feshbach–Villars Formalism

We analyse one-dimensional bound states of spin-zero particles coupled to external time-like vector potentials within the Feshbach–Villars representation. The study is organised around a practical criterion of physical admissibility that distinguishes genuine bound states from sc...

Geometric and wave optics analysis of BTZ-like charged wormholes with disclinations

We study the geometric and wave-optical properties of a charged BTZ wormhole (BTZCWH) spacetime carrying disclinations. The metric function \(f(r)=1-b_0/r-\mathcal {Q}^2 r^2/4\) has two positive zeros, an inner throat \(r_0\) and an outer zero \(r_*\) ; the static Lorentzian desc...
