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…
A Parabolic Model for the Dimple Potentials
Melike Çıbık Aydın, Haydar Uncu, Coşkun Deniz
We study truncated parabolic function and demonstrate that it is a representation of the Dirac delta function. We also show that the truncated parabolic function, used as a potenti…
Effect of Dimple Potential on Ultraslow Light in a Bose-Einstein Condensate
Devrim Tarhan, Haydar Uncu
We investigate the propagation of ultraslow optical pulse in atomic Bose-Einstein condensate in a harmonic trap decorated with a dimple potential. The role of dimple potential on t…
Reentrant phase transitions and multicompensation points in the mixed-spin Ising ferrimagnet on a decorated Bethe lattice
Jozef Strecka, Cesur Ekiz
Mixed-spin Ising model on a decorated Bethe lattice is rigorously solved by combining the decoration-iteration transformation with the method of exact recursion relations. Exact re…
