Origin of flat bands and non-trivial topology in coupled kagome lattices
Anumita Bose, Arka Bandyopadhyay, Awadhesh Narayan
We propose an exact analytical decimation transformation scheme to explore the fascinating coexistence of flat bands and Dirac fermions in three-dimensional coupled kagome systems.…
Berry Curvature Dipole and its Strain Engineering in Layered Phosphorene
Arka Bandyopadhyay, Nesta Benno Joseph, Awadhesh Narayan
The emergence of the fascinating non-linear Hall effect intrinsically depends on the non-zero value of the Berry curvature dipole. In this work, we predict that suitable strain eng…
Non-Hermitian Topology and Flat Bands via an Exact Real Space Decimation Scheme
Ayan Banerjee, Arka Bandyopadhyay, Ronika Sarkar +1
In recent years, non-Hermitian phases in classical and quantum systems have garnered significant attention. In particular, their intriguing band geometry offers a platform for expl…
