The mixed spin-1 and spin-3/2 BC Ising ferromagnetic system is studied on the two-fold Cayley tree by means of the exact recursion relations. The exact expressions for the magnetization, the quadripolar moment, the Curie temperature, and the free e [...]

We use exact recursion relations to study the magnetic properties of the half-integer mixed spin-5/2 and spin-3/2 Blume-Capel Ising ferromagnetic system on the two-fold Cayley tree that consists of two sublattices A and B. Two positive crystal-fiel [...]

In this paper, we use time-frequency analysis for pulse propagation in a linear dispersive medium. TheGaussian and sinh-Gaussian profiles are used as input ultra-short pulses (0,)in the time domain. E (0, ω) is the corresponding spectral [...]
The mixed spin-1 and spin-7/2 Blume-Capel model is investigated on the Bethe lattice in the presence of an external magnetic field h. The groundstate phase diagram which may be useful to explore interesting domains of the temperature phase diagrams o [...]

The ability to provide large electric field enhancements renders triangular nanoprisms and branched nanoparticles very attractive for applications in surface-enhanced Raman spectroscopy (SERS). Theoretical studies on the optical properties of trian [...]

This paper considers a novel approach to solving the general propagation equation of optical pulses in an arbitrary non-linear medium. Using a suitable change of variable and applying the Adomian decomposition method to the non-linear Schrödinger e [...]

We prove that the rank 3 analogue of the tensor model defined in Ben Geloun and Rivasseau (Commun Math Phys, arXiv:1111.4997 [hep-th], 2012) is renormalizable at all orders of perturbation. The proof is given in the momentum space. The one-loop γ- [...]
This paper stands for an application of the noncommutative (NC) Noether theorem, given in our previous work [AIP Proc 956 (2007) 55-60], for the NC complex Grosse-Widkenhaar model. It provides with an extension of a recent work [Physics Letters B 6 [...]
