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…
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…
A proposal for realizing Majorana fermions without external magnetic field in strongly correlated nanowires
Kaushal Kumar Kesharpu, Evgenii A. Kochetov, Alvaro Ferraz
We show that one dimensional (1D) topological superconductivity can be placed in the context of phenomena associated with strongly correlated electron systems. Here we propose a sy…
Topological Hall effect induced by classical large-spin background: path-integral approach
Kaushal K. Kesharpu, Evgenii A. Kochetov, Alvaro Ferraz
The coherent-state path-integral technique is employed to study lattice electrons strongly coupled to a quantum spin background. In the large-spin limit it is replaced with…
Spin-flip induced superfluidity in a ring of spinful hard-core bosons
K. K. Kesharpu, E. A. Kochetov
The t - J Hamiltonian of the spinful hard-core bosonic ring in the Nagaoka limit is solved. The energy spectrum becomes quantized due to presence of spin, where each energy level c…
Strong Correlation, Bloch Bundle Topology and Spinless Haldane-Hubbard Model
Ilya Ivantsov, Alvaro Ferraz, Evgenii Kochetov
Different realizations of the Hubbard operators in different Hilbert spaces give rise to various microscopic lattice electron models driven by strong correlations. In terms of the…
