We study the confinement of relativistic spin-one particles in two spatial dimensions by a quantum ring for systems described by the Duffin–Kemmer–Petiau (DKP) equation. The ring-like geometry is realized by introducing a pseudo-scalar funnel-sha

We consider the Duffin–Kemmer–Petiau (DKP) oscillator for spin-zero bosons, coupled to a pseudoscalar Coulomb potential, in a (3+1)-dimensional noncommutative space–time characterized by κ-deformation. We use the method of Dirac derivatives to

The Extended Uncertainty Principle (EUP) is a gravitational correction to quantum mechanics that extends and modifies Heisenberg’s uncertainty principle. Particularly, it suggests the existence of a minimum measurable momentum scale, often referred

The Snyder-de Sitter (SdS) algebra is a model of non-commutative space–time admitting three fundamental parameters: the speed of light, the Planck mass and the cosmological constant, and therefore can be seen as an example of triply special relativ

We consider a generalization of the Duffin–Kemmer–Petiau oscillator (DKPO) for spin-1 bosons, built by implementing an extra spin–orbit coupling (SOC) into the standard DKPO equation. This model meets the requirements of Lorentz covariance as w

We consider the relativistic quantum scattering of spinless particles in one-spatial dimension using the Feshbach-Villars formalism. We construct the general form of the scattering matrix, for symmetric and non-symmetric potentials, based on the symm

We study the perturbation of the one-dimensional generalized relativistic harmonic oscillator (GRHO) by a Lorentz scalar delta-shaped interaction. By exactly solving the implied Dirac equation, we show that the presence of the singular potential brin

The interest in physical systems with position-dependent mass (PDM) is always topical. In this work we present a new way to construct kinetic energy operators (KEO’s) for particles endowed with a position varying mass within the Schrödinger equati
