Hydrogen Atom: Its Spectrum and Degeneracy Importance of the Laplace-Runge-Lenz Vector
Akshay Pal, Siddhartha Sen
Consider the problem: why does the bound state spectrum , of hydrogen atom Hamiltonian have more degenerate eigenstates than those required by rotational symmetry? Th…
Holography in de Sitter and anti-de Sitter Spaces and Gel'fand Graev Radon transform
Samrat Bhowmick, Koushik Ray, Siddhartha Sen
Bulk reconstruction formulas similar to HKLL are obtained for de Sitter and anti-de Sitter spaces as the inverse Gel'fand Graev Radon transform. While these generalize our previous…
d-zero Magnetism in Nanoporous Amorphous Alumina Membranes
Amir Sajad Esmaeily, M. Venkatesan, S. Sen +1
Nanoporous alumina membranes produced by mild or hard anodisation in oxalic acid at potentials ranging from 5 - 140 V have a controllable pore surface area of up to 200 times the m…
Bulk reconstruction in AdS and Gel'fand-Graev-Radon Transform
Samrat Bhowmick, Koushik Ray, Siddhartha Sen
The bulk reconstruction formula for a Euclidean anti-de Sitter space is directly related to the inverse of the Gel'fand-Graev-Radon transform. Correlation functions of a conformal…
Emergence of Coherent Nanoscale Structures in Carbon Nantotubes
Siddhartha Sen, Kumar S. Gupta
Recently unusual properties of water in single-walled carbon nanotubes (CNT) with diameters ranging from 1.05 nm to 1.52 nm were observed. It was found that water in the CNT remain…
Collective magnetic response of CeO2 nanoparticles
J. M. D. Coey, Karl Ackland, M. Venkatesan +1
The magnetism of nanoparticles and thin films of wide-bandgap oxides that include no magnetic cations is an unsolved puzzle. Progress has been hampered both by the irreproducibilit…
