The Harmonic Oscillator Potential Perturbed by a Combination of Linear and Non-linear Dirac Delta Interactions with Application to Bose-Einstein Condensation
Cenk Akyüz, Fatih Erman, Haydar Uncu
In this paper, we study the bound state analysis of a one dimensional nonlinear version of the Schrödinger equation for the harmonic oscillator potential perturbed by a potenti…
Dynamic behavior of the antiferromagnetically coupled bilayer Ising model
C. Ekiz, R. Erdem, D. Semet
Using the path probability and lowest approximation of cluster variation method, we study the dynamic and equilibrium properties of a bilayer magnetic system, consisting of two fer…
Unsaturated bipartite entanglement of a spin-1/2 Ising-Heisenberg model on a triangulated Husimi lattice
Cesur Ekiz, Jozef Strecka
A bipartite entanglement between two nearest-neighbor Heisenberg spins of a spin-1/2 Ising-Heisenberg model on a triangulated Husimi lattice is quantified using a concurrence. It i…
A New Method for Derivation of Statistical Weight of the Gentile Statistics
Sevilay Selvi, Haydar Uncu
We present a new method for obtaining the statistical weight of the Gentile Statistics. In a recent paper, Perez and Tun presented an ap- proximate combinatoric and an exact recurs…
Is order-by-disorder present or absent in a highly frustrated region of the spin-1/2 Ising-Heisenberg model on triangulated Husimi lattices?
J. Strecka, C. Ekiz
The geometrically frustrated spin-1/2 Ising-Heisenberg model on triangulated Husimi lattices is exactly solved by combining the generalized star-triangle transformation with the me…
Magnetization process in the exactly solved spin-1/2 Ising-Heisenberg model on decorated Bethe lattices
J. Strecka, C. Ekiz
The spin-1/2 Ising-Heisenberg model on diamond-like decorated Bethe lattices is exactly solved in the presence of the longitudinal magnetic field by combining the decoration-iterat…
