“…Various additional couplings, impossible to be explored in conventional Klein-Gordon and Proca equations, gave rise to a large area of physical applications such as describing the scattering of mesons by nuclei [5][6][7], the dynamics of bosons in curved space-time [8] and noninertial effect of rotating frames [9], thermodynamic properties of bosons in noncommutative plane [10], all works involving spin 0 systems. Vector bosons in the expanding universe [11] and in an Aharonov-Bohm potential [12] are examples of applications to spin 1 systems. The Bose-Einstein condensate [13,14], very special relativity [15], among others works, are applications for both spin systems.…”

The dynamics of relativistic bosons (scalar and vectorial) through nonminimal vector square (well and barrier) potentials is studied in the Duffin-Kemmer-Petiau (DKP) formalism. We show that the problem can be mapped in effective Schrödinger equations for a component of the DKP spinor. An oscillatory transmission coefficient is found and there is total reflection. Additionally, the energy spectrum of bound states is obtained and reveals the Schiff-Snyder-Weinberg effect, for specific conditions the potential lodges bound states of particles and antiparticles.

The quantum gravity correction to the Hawking temperature of the 2+1 dimensional spinning dilaton black hole is studied by using the Hamilton-Jacobi approach in the context of the Generalized Uncertainty Principle (GUP). It is observed that the modified Hawking temperature of the black hole depends on both black hole and the tunnelling particle properties. Moreover, it is observed that the mass and the angular momentum of the scalar particle have the same effect on the Hawking temperature of the black hole, while the mass and total angular momentum (orbital+spin) of Dirac particle have different effect. Furthermore, the mass and total angular momentum (orbital+spin) of vector boson particle have a similar effect that of Dirac particle. Also, thermodynamical stability and phase transition of the black hole are discussed for scalar, Dirac and vector boson in the context of GUP, respectively. And, it is observed that the scalar particle probes the black hole as stable whereas, as for Dirac and vector boson particles, it might undergoes secondtype phase transition to become stable while in the absence of the quantum gravity effect all of these particle probes the black hole as stable.

We study a quantum analogy of Schumann resonances by solving massless and massive spin-1 particle equations derived from the Zitterbewegung model in an annular cavity background with poorly conducting walls. We also show that the massless case and the massive case in the m 2 0 → 0 limit are compatible with Maxwell's electromagnetic theory. Furthermore, from the massive case, we predict an upper limit for the mass of the photon of 1.3x10 −50 kg. The bound on the mass of the photon is compatible with the current limit in the literature.
