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…

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…

Non-trivial Topological Phases on the Stuffed Honeycomb Lattice
Arghya Sil, Asim Kumar Ghosh
We report the appearance of nontrivial topological phases in a tight-binding model on the stuffed honeycomb lattice. The model contains nearest neighbor and next nearest neighbor h…
