Temperature dependence of resistivity and Hall-coefficient in a strongly disordered metal: NbN
Madhavi Chand, Archana Mishra, Y. M. Xiong +8
We report the temperature dependence of resistivity (rho) and Hall coefficient (R_H) in the normal state of homogeneously disordered epitaxial NbN thin films with kFl~3.27-10.12. T…
Robust Watermarking in Multiresolution Walsh-Hadamard Transform
Gaurav Bhatnagar, Balasubramanian Raman
In this paper, a newer version of Walsh-Hadamard Transform namely multiresolution Walsh-Hadamard Transform (MR-WHT) is proposed for images. Further, a robust watermarking scheme is…
Tunneling studies in a homogeneously disordered s-wave superconductor: NbN
S. P. Chockalingam, Madhavi Chand, Anand Kamlapure +4
We report the evolution of superconducting properties as a function of disorder in homogeneously disordered epitaxial NbN thin films grown on (100) MgO substrates, studied through…
Boundary S-matrix in a (2,0) theory of AdS_{3} Supergravity
Payal Kaura, Bindusar Sahoo
We will discuss two inequivalent generalizations of the standard (2,0) supergravity action gr-qc/9501018 to include gravitational Chern-Simons term. One is in the first order forma…
Dissociation of quarkonium in hot QCD medium: Modification of the inter-quark potential
Vineet Agotiya, Vinod Chandra, Binoy Krishna Patra
We have studied the dissociation of heavy quarkonium states in a hot QCD medium by investigating the medium modifications to a heavy quark potential. Our model shows that in-medium…
Large Volume Axionic Swiss-Cheese Inflation
Aalok Misra, Pramod Shukla
Continuing with the ideas of (section 4 of) [1], after inclusion of perturbative and non-perturbative alpha' corrections to the Kaehler potential and (D1- and D3-) instanton genera…
