Observation of complete delocalization in disordered photonic lattices
Biplab Pal, Rodrigo A. Vicencio
We present the exceptional phenomenon of complete absence of Anderson localization, and perfect transmission of particles, in a completely disordered diamond-dot chain. We analytic…
Flux-induced strengthening of the magnetic couplings in a flat-band diamond chain
Biplab Pal, Maxime Thumin, Georges Bouzerar
The physics in flat bands has emerged as an essential field in condensed matter physics where a plethora of phenomena can be unveiled, such as anomalous transport properties, super…
Compact localized states and magnetic flux-driven topological phase transition in a diamond-dodecagon lattice geometry
Joydeep Majhi, Biplab Pal
We propose and investigate a novel two-dimensional (2D) tight-binding model defined on a diamond-dodecagon lattice geometry that hosts multiple flat bands (FBs) and supports topolo…
Proximity-induced flat bands and topological properties in a decorated diamond chain
K Shivanand Thakur, Vihodi Theuno, Amrita Mukherjee +1
In the present study, we propose a unique scheme to generate and control multiple flat bands in a decorated diamond chain by using a strain-induced proximity effect between the dia…
Aharonov-Bohm caging of an electron in a quantum fractal
Biplab Pal
Fractal geometries exhibit complex structures with scale invariance self-similar pattern over various length scales. An artificially designed quantum fractal geometry embedded in a…
A fractal geometry immersed in a hierarchical magnetic flux distribution
Biplab Pal
Fractal geometry presents us with a self-similarity in their pattern at various length scales that is prevalent in our natural world. We present theoretical model of a Sierpinski g…
