AbstractThe Snyder-de Sitter (SdS) model which is invariant under the action of the de Sitter group, is an example of a noncommutative space-time with three fundamental scales. In this paper, we considered the massless Dirac fermions in graphene layer in a curved Snyder space-time which are subjected to an external magnetic field. We employed representation in the momentum space to derive the energy eigenvalues and the eigenfunctions of the system. Then, we used the deduced energy function obtaining the internal energy, heat capacity, and entropy functions. We investigated the role of the fundamental scales on these thermal quantities of the graphene layer. We found that the effect of the SdS model on the thermodynamic properties is significant.

Uvarov Method

The eigensolutions of massive spin-0 and spin-1 particles of a Dirac oscillator in an external magnetic field, both in the commutative and noncommutative space, are found by using the Duffin–Kemmer–Petiau equation. The solutions in both cases are obtained using the parametric generalization of the Nikiforov–Uvarov method.

Constant External Magnetic Field

The effective Lagrangian to one-loop order is calculated for N = 2 supergravity in flat space-time in the presence of a constant external magnetic field. The divergences that occur are not renormalizable; this is not unexpected since the background fields do not satisfy the classical equations of motion.
