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…
First and Second Order Topological Phases on Ferromagnetic Breathing Kagome Lattice
Arghya Sil, Asim Kumar Ghosh
In this work, topological properties of a ferromagnetic Heisenberg model on a breathing kagome lattice are investigated extensively in the presence of Dzyaloshinskii-Moriya interac…
Tunable wavevector filtering in borophane based normal metal-barrier-normal metal junctions
Prasun Das, Sangita De Sarkar, Asim Kumar Ghosh
We study the transport properties of Dirac electrons across a two-dimensional normal metal-barrier-normal metal (NBN) interfaces in monolayer borophane. We analyse the transmission…
Antikink dispersions of the - sawtooth spin-1/2 anisotropic Heisenberg antiferromagnetic chain
Susobhan Paul, Asim Kumar Ghosh
Antikink dispersion of the asymmetric - sawtooth spin-1/2 anisotropic Heisenberg antiferromagnetic chain has been derived. Value of spin-gap is obtained by estimating the…
Emergence of photo-induced multiple topological phases on square octagon lattice
Arghya Sil, Asim Kumar Ghosh
In this study, a tight-binding model on square octagon lattice with nearest-neighbour and next-nearest-neighbour hoppings is considered. The system is topologically trivial althoug…
