Flat bands and entanglement in the Kitaev ladder
Ritu Nehra, Devendra Singh Bhakuni, Ajith Ramachandran +1
We report the existence of \emph{flat bands} in a p-wave superconducting Kitaev ladder. We identify two sets of parameters for which the Kitaev ladder sustains flat bands. These fl…
Topological flat Wannier-Stark bands
Andrey R. Kolovsky, Ajith Ramachandran, Sergej Flach
We analyze the spectrum and eigenstates of a quantum particle in a bipartite two-dimensional tight-binding dice network with short range hopping under the action of a dc bias. We f…
Chiral Flat Bands: Existence, Engineering and Stability
Ajith Ramachandran, Alexei Andreanov, Sergej Flach
We study flat bands in bipartite tight-binding networks with discrete translational invariance. Chiral flat bands with chiral symmetry eigenenergy E = 0 and host compact localized…
