ERRATUM: Néel State in the Fermionized Spin 12\frac{1}{2} Heisenberg Antiferromagnet on Hypercubic and Triangular Lattices [Pham Thi Thanh Nga and Nguyen Toan Thang, Comm. Phys. 22\textit{Comm. Phys. } \textbf{22} (1) (2012) 33]


We study magnetic properties of ordered phase in Heisenberg model on a non-Bravais lattice by means of Popov - Fedotov trick, which takes into account a rigorous constraint of a single occupancy. We derive magnetization and free energy using sadle point a... see more

We study the magnetic ordered phases of the spin -12-\frac{1}{2} Heisenberg antiferromagnetic model with nearest J1J_1 and next nearest neighbor J2J_2 exchange interactions on the square lattice using fermionic representation of spin operators within Pop... see more

We study the Néel state of the spin 1/2 Heisenberg antiferromagnet model on hypercubic and triangular lattices, employing an auxiliary fermion representation for spin operators with Popov-Fedotov trick. The unphysical states are eliminated on each site b... see more

We have analyzed the spin-1/2 isotropic Heisenberg antiferromagnetic system on triangular lattice within Popov--Fedotov functional intergral formalism when the spin operators are represented by the fermionic ones and the constraint of single occupancy con... see more

This study focuses on the influence of gold nanoparticle sizes on optical and electrical properties of Au@TiO2 nanocomposite films. Here, the gold nanoparticles (AuNPs) of different sizes of 5 nm, 10 nm, 20 nm, 40 nm and 60 nm were dispersed onto nanoporo... see more

In this paper, we report the development of the spray pyrolysis technique for preparing different nano-structure materials toward the application in thin film solar cells. The spray pyrolysis system can heat up the substrate to 6000C with less than 0.01% ... see more
