Magnetic field induced topological nodal-lines in triplet excitations of frustrated antiferromagnet CaVO
Moumita Deb, Asim Kumar Ghosh
Magnetic field induced multiple non-Dirac nodal-lines are found to emerge in the triplet dispersion bands of a frustrated spin-1/2 antiferromagnetic model on the CaVO lattice. Plaq…
Topological magnons in ferromagnetic Kitaev-Heisenberg model on CaVO lattice
Moumita Deb, Asim Kumar Ghosh
A number of topological phases are found to emerge in the ferromagnetic Kitaev-Heisenberg model on CaVO lattice in the presence of Dzyaloshinskii-Moriya interaction. Heisenberg and…
Topological phases of higher Chern numbers in Kitaev-Heisenberg ferromagnet with further-neighbor interactions
Moumita Deb, Asim Kumar Ghosh
Emergence of multiple topological phases with a series of Chern numbers, , , , , and , are observed in a ferromagnetic Kitaev-Heisenberg-…
Exotic topological point and line nodes in the plaquette excitations of a frustrated Heisenberg antiferromagnet on the honeycomb lattice
Moumita Deb, Asim Kumar Ghosh
A number of topological nodes including Dirac, quadratic and triple band touching points as well as a pair of degenerate Dirac line nodes are found to emerge in the triplet plaquet…
Thermally stable multipartite entanglements in the frustrated Heisenberg hexagon
Moumita Deb, Asim Kumar Ghosh
Thermally stable quantum states with multipartite entanglements led by frustration are found in the antiferromagnetic spin-1/2 Heisenberg hexagon. The model has been solved exactly…
