Rotated Dn-lattices
Grasiele Cristiane Jorge, Agnaldo José Ferrari, Sueli Irene Rodrigues Costa
Based on algebraic number theory we construct some families of rotated Dn-lattices with full diversity which can be good for signal transmission over both Gaussian and Rayleigh fad…
Effective carrying capacity and analytical solution of a particular case of the Richards-like two-species population dynamics model
Brenno Caetano Troca Cabella, Fabiano Ribeiro, Alexandre Souto Martinez
We consider a generalized two-species population dynamic model and analytically solve it for the amensalism and commensalism ecological interactions. These two-species models can b…
Thermal Entanglement of a Spin-1/2 Ising-Heisenberg Model on a Symmetrical Diamond Chain
N. S. Ananikian, L. N. Ananikyan, L. A. Chakhmakhchyan +1
The entanglement quantum properties of a spin-1/2 Ising-Heisenberg model on a symmetrical diamond chain were analyzed. Due to the separable nature of the Ising-type exchange intera…
Spin-phonon coupling induced frustration in the exactly solved spin-1/2 Ising model on a decorated planar lattice
Jozef Strecka, Onofre Rojas, Sergio Martins de Souza
The spin-1/2 Ising model with a spin-phonon coupling on decorated planar lattices partially amenable to lattice vibrations is examined within the framework of the generalized decor…
Spontaneous distortion in the spin-1/2 Ising-Heisenberg model on decorated planar lattices with a magnetoelastic coupling
Jozef Strecka, Onofre Rojas, S. M. de Souza
Magnetoelastic properties of the spin-1/2 Ising-Heisenberg model on doubly decorated planar lattices partially amenable to lattice vibrations are examined within the framework of t…
Frustrated Ising model on the Cairo pentagonal lattice
M. Rojas, Onofre Rojas, S. M. de Souza
Through the direct decoration transformation approach, we obtain a general solution for the pentagonal Ising model, showing its equivalence to the isotropic free-fermion eight-vert…
