Local magnetic properties of periodic nonuniform spin-1/2 XX chains
Oleg Derzhko, Johannes Richter, Oles' Zaburannyi
Using the Jordan-Wigner fermionization, Green function approach and continued fractions we examine rigorously the local magnetizations and the local static susceptibilities of the…
Spin-Peierls instability in a quantum spin chain with Dzyaloshinskii-Moriya interaction
O. Derzhko, J. Richter, O. Zaburannyi
We analysed the ground state energy of some dimerized spin-1/2 transverse XX and Heisenberg chains with Dzyaloshinskii-Moriya (DM) interaction to study the influence of the latter…
Nucleation phenomena in a nonuniform atomic fluid in the electrical field
O. V. Derzhko, V. M. Myhal
The density functional approach is used to study the gas-to-liquid and liquid-to-gas nucleation phenomena in a fluid of two-level atoms in an external electrical field. The influen…
Dynamics of spin correlations in the spin-1/2 isotropic XY chain in a transverse field
O. Derzhko, T. Krokhmalskii, J. Stolze
Dynamic xx spin pair correlation functions for the isotropic spin-1/2 XY chain are calculated numerically for long open chains in the presence of a transverse magnetic field at fin…
Incommensurate Spin-Peierls Phases in the One-Dimensional Quantum Isotropic XY Model
Oleg Derzhko, Taras Krokhmalskii
Using the numerical approach for a study of the thermodynamic properties of the nonuniform one-dimensional spin-1/2 isotropic XY model in a transverse field we examine different la…
Thermodynamic properties of the periodic nonuniform spin-1/2 isotropic XY chains in a transverse field
Oleg Derzhko, Johannes Richter, Oles' Zaburannyi
Using the Jordan-Wigner transformation and the continued-fraction method we calculate exactly the density of states and thermodynamic quantities of the periodic nonuniform spin-1/2…
