Effects of frustration and Dzyaloshinskii-Moriya interaction on the spin-1/2 anisotropic Heisenberg antiferromagnet with the application to La2CuO4
Milica Rutonjski, Milan Pantic, Milica Pavkov-Hrvojevic
We study the magnetic properties of the two-dimensional anisotropic antiferromagnetic spin-1/2 Heisenberg model with Dzyaloshinskii-Moriya interaction and in-plane frustration incl…
Dynamics of Frenkel excitons in pentacene
Sonja Gombar, Petar Mali, Milan Pantić +2
The dispersion relation for noninteracting excitons and the influence of perturbative correction is examined in the case of pentacene structure. The values of exchange integrals ar…
Correlation between quantum entanglement and quantum coherence in the case of XY spin chains with the Dzyaloshinskii-Moriya interaction
Sonja Gombar, Petar Mali, Milan Pantic +2
Recently, there has been an increased interest in studying quantum entanglement and quantum coherence. Since both of these properties are attributed to the existence of quantum sup…
Phase diagram of spin- quantum Heisenberg antiferromagnet on the body-centered-cubic lattice in random phase approximation
Milan R. Pantic, Darko V. Kapor, Slobodan M. Radosevic +1
Magnetic properties of spin Heisenberg antiferromagnet on body centered cubic lattice are investigated. By using two-time temperature Green's functions, sublat…
Magnon Energy Renormalization and Low-Temperature Thermodynamics of O(3) Heisenberg Ferromagnets
Slobodan M. Radosevic, Milan R. Pantic, Milica V. Pavkov-Hrvojevic +1
We present the perturbation theory for lattice magnon fields of -dimensional O(3) Heisenberg ferromagnet. The effective Hamiltonian for the lattice magnon fields is obtained sta…
