Heat capacity of Schottky type in low-dimensional spin system
Saeed Mahdavifar, Alireza Akbari
The heat capacity of low-dimensional spin systems is studied using theoretical and numerical techniques. Keeping only two energy states, the system is mapped onto the two -level-sy…
Quadrupole Effect on the Heat Conductivity of Cold Glasses
Alireza Akbari
At very low temperatures, the tunnelling theory for amorphous solids predicts a thermal conductivity , with . We have studied the effect of the Nuclear Quadrup…
Alternating Heisenberg Spin-1/2 Chains in a Transverse Magnetic Field
Saeed Mahdavifar, Alireza Akbari
The ground state phase diagram of the alternating spin-1/2 chains with anisotropic ferromagnetic coupling under the influence of a symmetry breaking transverse magnetic field is st…
Dielectric Susceptibility and Heat Capacity of Ultra-Cold Glasses in Magnetic Field
Alireza Akbari, D. Bodea, A. Langari
Recent experiments demonstrated unexpected, even intriguing properties of certain glassy materials in magnetic field at low temperatures. We have studied the magnetic field depende…
