Thermodynamic Properties of 1d Heisenberg Model. Magnetic Moment of Spinon
W. McRae, O. Sushkov
The one dimensional spin 1/2 Heisenberg antiferromagnet is considered using a simple quasiparticle picture - an interacting Fermi gas of kinks. Using this picture the low temperatu…
Hole Photoproduction in Insulating Copper Oxide
O. Sushkov, G. Sawatzky, R. Eder +1
To explain the experimental spectra for angle resolved photoemission we consider a modified t-J model. The modified model includes next nearest (t') and next next nearest (t'') hop…
Static and Dynamic Spin Structure Factors of Frustrated Heisenberg Antiferromagnet
O. P. Sushkov
Using the modified spin-wave theory we calculate static and dynamic spin structure factors in spin-liquid state of the J1-J2 model. The spectrum of excitations in the vector channe…
Quantum melting of the long-range antiferromagnetic order and spin-wave condensation in t-J-V model
M. Yu. Kuchiev, O. P. Sushkov
We consider two-dimensional t-J-V model. The wave function of the ground state is constructed. We demonstrate that the doping by holes results in condensation of the spin-waves, de…
