Engineering slow light and mode crossover in a fractal-kagome waveguide network
Atanu Nandy, Arunava Chakrabarti
We present an analytically exact scheme of unraveling a multitude of flat, dispersionless photonic bands in a kagome waveguide strip where each elementary plaquette hosts a determi…
Absolute L-shell ionization and X-ray production cross sections of Lead and Thorium by 16-45 keV electron impact
H. V. Rahangdale, P. K. Das, S. De +4
The absolute L subshell specific electron impact ionization cross sections near the ionization threshold (16 < E < 45 keV) of Lead and Thorium are obtained from the measured L X-ra…
Engineering flat electronic bands in quasiperiodic and fractal loop geometries
Atanu Nandy, Arunava Chakrabarti
Exact construction of one electron eigenstates with flat, non-dispersive bands, and localized over clusters of various sizes is reported for a class of quasi-one dimensional looped…
Validating variational principle for higher order theory of gravity
Soumendranath Ruz, Kaushik Sarkar, Nayem Sk +1
Metric variation of higher order theory of gravity requires to fix the Ricci scalar in addition to the metric tensor at the boundary. Fixing Ricci scalar at the boundary implies th…
Flat band analogues and flux driven extended electronic states in a class of geometrically frustrated fractal networks
Atanu Nandy, Biplab Pal, Arunava Chakrabarti
We demonstrate, by explicit construction, that a single band tight binding Hamiltonian defined on a class of deterministic fractals of the b = 3N Sierpinski type can give rise to a…
