Quantum selection of order and dynamic properties of Kitaev-Heisenberg ferromagnet on a triangular lattice
Kaushal K. Kesharpu, Pavel A. Maksimov
Recent interest in monolayer materials motivated a search for two-dimensional ferromagnets with sizable spin-orbit coupling. Magnetic anisotropy of exchange Hamiltonian, induced by…
A method to treat strongly correlated topological superconductors in one and two dimensions
Kaushal Kumar Kesharpu, Evgenii A. Kochetov, Alvaro Ferraz
In the strong electron-electron (e-e) interaction limit each atomic site is constrained to be either empty or singly occupied. One can treat this scenario by fractionalizing the el…
Re-entrant topological order in strongly correlated nanowire due to Rashba spin-orbit coupling
Kaushal Kumar Kesharpu, Evgenii A. Kochetov, Alvaro Ferraz
The effect of the Rashba spin orbit coupling (RSOC) on the topological properties of the one-dimensional (1D) extended -wave superconducting Hamiltonian, in the presence of stro…
Anisotropic zero-resistance onset in organic superconductors
Vladislav D. Kochev, Kaushal K. Kesharpu, Pavel D. Grigoriev
We study the coexistence of superconductivity (SC) and density-wave state and reconcile various puzzling experimental data in organic superconductors (TMTSF)PF and (TMT…
