My fields of research
My thesis used statistical and computational techniques
to study the morphology and dynamics of the Solar Ca II K (393.4 nm)
chromospheric network and the associated supergranular network
magnetic fields. The data I used were SoHO
dopplergrams and magnetograms, Ca II K line images from the Kodaikanal
Obseratory, the Swedish Vacuum Solar Telescope (SVST), Antarctica and
G band (430.5 nm)images from SVST. I used astronomy software
packages like IRAF and IDL for image processing and analysis, apart from
C programs for plain numerical computation.
We studied the dependence of network evolution on activity level
(Raju, Srikanth and Singh 1998a), and on network
scales (Srikanth, Singh and Raju 1999), and of
scales on heliographic latitude (Raju, Srikanth and Singh
1998b) . Network evolution was shown to be compatible to model of
diffusion of network magnetic fields
(Srikanth, Raju and Singh 1999) .
An undulatory signal observed in the temporal correlation function
has been noted
(Raju, Singh, Srikanth et al. 2000) .
A computational pattern-recognition algorithm of tessellation was used to study
network structure at various temporal and spatial scales
(Srikanth, Singh and Raju 2000) in K line filtergrams and SoHO
dopplergrams.
At present the technique is being applied to SoHO full disk magnetograms.
We made a comparative study of the dynamics and morphology of associated
Ca II K and G Band bright points
(Krishnakumar, Venkatakrishnan and Srikanth 2000) .
Although the prevalent mathematical description of the Poynting-Robertson
effect is correct, its physical interpretation is sometimes problematic.
By means of a two-parameter model, we revisit the effect
in order to get a better physical understanding of it. The principal
conclusion is that the motion of a dust in circumsolar orbit is governed
only by solar radiation absorption and not by the asymmetry of
re-emission, even when viewed in the rest-frame of the Sun
(Srikanth 1999b) .
I am interested in understanding better the meaning of quantum nonlocality.
Is the violation of Bell's inequality by quantum mechanics the strongest
statement we can make about the quantum nonlocality? I think not! In a
generalization of the EPR thought experiment, I have pointed out that
subtle correlation effects
between nonlocal measurements permit classical signaling
(Srikanth 2001a ). I have managed to design a more
practical quantum optical test for the same (Srikanth
2001b).
A question that fascinates me is whether the nonclassical aspects of
qauntum mechanics hint at the deep-rooted information theoretic character of
Nature. As a first step towards this, one might learn to interpret
quantum mechanics information theoretically rather than stretch classical
concpts and usages (Srikanth 2001c).
I have compiled notes from some lectures on quantum information and
computation I had given at the NAPP group. You can find them
here. Note that they are somewhat
sketchy now.
