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]

Erratum: Mott Transition in the Mass Imbalanced Ionic Hubbard Model at Half Filling[Nguyen Thi Hai Yen, Le Duc Anh, Hoang Anh Tuan, Nguyen Toan Thang and Tran Thi Thu Trang, Communications in Physics, Vol. 29, No. 3SI (2019), pp. 305-312]This paper was pu... see more






The Mott - Hubbard metal - insulator transition in the half-filled mass imbalanced ionic Hubbard model is investigated using the two-site dynamical mean field theory. We find that for a fixed mass imbalanced parameter r the critical interaction Uc increas... see more

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
