Evolution of the density parameter in the anisotropic DGP cosmology
Rizwan Ul Haq Ansari, P. K. Suresh
Evolution of the density parameter in the anisotropic DGP braneworld model is studied. The role of shear and cross-over scale in the evolution of is examined for both the bra…
Near dispersion-less surface plasmon polariton resonances at a metal-dielectric interface
Sachin Kasture, P. Mandal, Amandev Singh +5
Omni-directional light coupling to surface plasmon polariton (SPP) modes to make use of plasmon mediated near-field enhancement is challenging. We report possibility of near disper…
Line discontinuities, local action with both the field and its dual, and spin from no spin in two-dimensional scalar theory
Chandrasekhar Chatterjee, E. Harikumar, Manu Mathur +2
We consider a local action with both the real scalar field and its dual in two Euclidean dimensions. The role of singular line discontinuities is emphasized. Exotic properties of t…
Neutrino mixing matrices with relatively large and with texture one-zero
K. N. Deepthi, Srinu Gollu, R. Mohanta
The recent T2K, MINOS and Double Chooz oscillation data hint a relatively large , which can be accommodated by some general modification of the Tribimaximal/Bimaximal/Democ…
Self assembly of microparticles in stable ring structures in an optical trap
Arijit Haldar, Sambit Bikas Pal, Basudev Roy +2
Micro-particle self assembly under the influence of optical forces produced by higher order optical beams or by projection of a hologram into the trapping volume is well known. In…
Exceptional Polynomials and SUSY Quantum Mechanics
K. V. S. Shiv Chaitanya, S. Sree Ranjani, Prasanta K. Panigrahi +2
We show that the existence of exceptional polynomials leads to the presence of non-trivial supersymmetry. The existence of these polynomials reveals several distinct isospectral po…
