Topological characterization of special edge modes from the winding of relative phase
Sudarshan Saha, Tanay Nag, Saptarshi Mandal
The symmetry-constrained topological invariant fails to explain the emergence of the special edge modes when system does not preserve discrete symmetries. The inversion or chiral s…

Eight fold quantum Hall phases in a time reversal symmetry broken tight binding model
Sudarshan Saha, Tanay Nag, Saptarshi Mandal
We consider a time reversal symmetry (TRS) broken Kane-Mele model superimposed with Haldane model and chart out the phase diagram using spin Chern number to investigate the fate of…

Existence of nodal line semi-metal in a generalized three dimensional Haldane model
Sudarshan Saha, Saptarshi Mandal
We construct and study a time reversal broken tight binding model on diamond lattice with complex next-nearest-neighbour hopping which can be thought of as a generalisation of two…
