Engineering flux-controlled flat bands and topological states in a Stagome lattice
Biplab Pal, Georges Bouzerar
We present the Stagome lattice, a variant of the Kagome lattice, where one can make any of the bands completely flat by tuning an externally controllable magnetic flux. This system…
Flat bands and nontrivial topological properties in an extended Lieb lattice
Ankita Bhattacharya, Biplab Pal
We report the appearance of multiple numbers of completely flat band states in an extended Lieb lattice model in two dimensions with five atomic sites per unit cell. We also show t…
Anyons and Fractional Quantum Hall Effect in Fractal Dimensions
Sourav Manna, Biplab Pal, Wei Wang +1
The fractional quantum Hall effect is a paradigm of topological order and has been studied thoroughly in two dimensions. Here, we construct a new type of fractional quantum Hall sy…
Quasiperiodic magnetic chain as a spin filter for arbitrary spin states
Biplab Pal
We show that a quasiperiodic magnetic chain comprising magnetic atomic sites sequenced in Fibonacci pattern can act as a prospective candidate for spin filters for particles with a…
Nontrivial topological flat bands in a diamond-octagon lattice geometry
Biplab Pal
We present the appearance of nearly flat band states with nonzero Chern numbers in a two-dimensional "diamond-octagon" lattice model comprising two kinds of elementary plaquette ge…
Flat bands in fractal-like geometry
Biplab Pal, Kush Saha
We report the presence of multiple flat bands in a class of two-dimensional (2D) lattices formed by Sierpinski gasket (SPG) fractal geometries as the basic unit cells. Solving the…
