Critical Phases of the extended isotropic chain with four-spin interaction
Nika Kurdadze, Giorgi Gogaberishvili, G. I. Japaridze
Using the Jordan-Wigner transformation we calculate exactly the ground state and low-temperature thermodynamic properties of the spin isotropic chain with four spin in…
Thermal Order by Disorder in Resonating-Valence Bond States on the Checkerboard Lattice
Giorgi Gogaberishvili, Nika Kurdadze, Kirill Shtengel
We derive a local spin-1/2 Hamiltonian with a resonating valence bond ground state on the checkerboard lattice. The state is characterized by the exponential decay of singlet-singl…
Synchrotron emission from a nearby zone of SgrA
G. Gogaberishvili, Z. N. Osmanov, S. M. Mahajan
Quasi-linear diffusion (QLD), driven by the cyclotron instability, is proposed as a mechanism for the possible generation of synchrotron emission in the nearby zone of SgrA. Fo…
