Raman with the main objective of promoting the progress and upholding the cause of science (both pure and applied). It was registered as a Society under the Societies Registration Act on 24 April 1934. The Academy commenced functioning with 65 Fellows and the formal inauguration took place on 31 July 1934 at the Indian Institute of Science, Bangalore. On the afternoon of that day its first general meeting of Fellows was held where Sir C.V. Raman was elected its President and the draft constitution of the Academy was approved and adopted. The first issue of the Academy Proceedings was published in July 1934. The present report covering the period from April 2007 to March 2008 represents the seventy-fourth year of the Academy. -
Amitava Raychaudhuri
Amitava Raychaudhuri Research Summary: In 2007-08, research has been carried out in aspects of neutrino physics, particle physics models based on space-time with extra dimensions, and quark models. In continuing work on the prospects of the proposed Iron Calorimeter detector at INO being used as an end-detector for a very long baseline experiment in con- junction with a beta-beam source in Europe, it has been shown that this set-up has unmatched sensitivity for probing many of the remaining unknowns of the neutrino mass matrix. Related work on long baseline experiments with a beta- beam have (a) explored the possibility of using the survival probability Pee and (b) optimised the baseline, boost-factor, and luminosities for the best reach for probing the open issues of neutrino physics. The upper bound on the mass of the lightest neutral higgs scalar is shown to be considerably relaxed in models in which SUSY is embedded in space-time of more than four dimensions. Even though the observational evidence for the ‘pentaquark’ is currently not strong, such a bound state is a consequence of QCD. The group theory of the ‘triquark’ – which is a aconstitutent of the pentaquark – has been examined with a focus on the colour-spin SU(6) structure. Using these results, the masses of the different pentaquak states and their colour-spin excitations have been estimated. Publications: 1.

Abstract We consider a 5-dimensional SU(5) model wherein the symmetry is broken to the 4-dimensional 1 Standard Model by compactification of the 5th dimension on an S /(Z2 x Z'2) orbifold. We identify the members of all SU(5) representations upto 75 which have zero modes. We examine how these light scalars affect gauge coupling unification assuming a single intermediate scale and present several acceptable solutions. The 5-D compactification scale coincides with the unification scale of gauge couplings and is determined via this renormalization group analysis. When 5(9(10) is considered as the GUT group there are only two solutions, so long as a few low dimensional scalar multiplets upto 126 are included. -

To, Prof. Ajit Kembhavi, President, ASI CC : Prof. Dipankar Banerjee, Secretary, ASI Subject : Formation of Working Group for Gender Equity Dear Sir, We, the undersigned, members of the Indian Astronomy & Astrophysics community (from a number of academic institutions), would like to request you for the formation of a working group for gender equity under the aegis of ASI. To this effect we hereby submit a formal proposal giving details of the rational behind such a working group and a brief outline of the role we would like the working group to play. We hope you would take cognizance of the fact that a significant fraction of our community feel that the formation of such a group is the need of the hour. For the Working Group to better serve the needs of the entire astronomy community, it would be advantageous if its constituted members reflect the diversity of the community in gender, age, affiliation, geographical region etc. In addition, in the interest of promoting equity in gender representation, we feel it is best chaired by a woman astronomer. Hoping to receive a positive response from you. Yours sincerely, The Proposers of the Working Group The Proposers : A core group of people (Preeti Kharb, Sushan Konar, Niruj Mohan, L. Resmi, Jasjeet Singh Bagla, Nissim Kanekar, Prajval Shastri, Dibyendu Nandi etc.) have been working towards sensitising the Indian Astronomical community about gender related issues and proposing the formation of a working group, with significant input from a number of others. However, a large section of the community have been supportive of this activity and would like to be a part of this initiative. -
Dynamics and Chaos in the Unified Scalar Field Cosmology
Dynamics and chaos in the unified scalar field Cosmology Georgios Lukes-Gerakopoulos,1,2 Spyros Basilakos,1 and George Contopoulos1 1Academy of Athens, Research Center for Astronomy, Soranou Efesiou 4, GR-11527, Athens, GREECE 2University of Athens,Department of Physics, Section of Astrophysics, Astronomy and Mechanics We study the dynamics of the closed scalar field FRW cosmological models in the framework of the so called Unified Dark Matter (UDM) scenario. Performing a theoretical as well as a numerical analysis we find that there is a strong indication of chaos in agreement with previous studies. We find that a positive value of the spatial curvature is essential for the appearance of chaoticity, though the Lyapunov number seems to be independent of the curvature value. Models that are close to flat (k 0+) exhibit a chaotic behavior after a long time while pure flat models do not exhibit any chaos.→ Moreover, we find that some of the semiflat models in the UDM scenario exhibit similar dynamical behavior with the Λ cosmology despite their chaoticity. Finally, we compare the measured evolution of the Hubble parameter derived from the differential ages of passively evolving galaxies with that expected in the semiflat unified scalar field cosmology. Based on a specific set of initial conditions we find that the UDM scalar field model matches well the observational data.

Amitava Raychaudhuri
Amitava Raychaudhuri Research Summary: In 2006-07, research has been carried out in aspects of neutrino physics, models based on space-time with extra dimensions, and grand unified theories. These are briefly discussed in turn below. In neutrino physics, a considerable effort has been spent on the prospects of a beta- beam facility { a source of pure νe or ν¯e beams. It has been shown that such a facility has unique advantages in both long- and short-baseline set-ups to better determine and constrain neutrino mass and mixing parameters as well as to explore non-Standard physics, like R-parity violating supersymmetry. Research has also been carried out to determine how well the ICAL detector at INO will be able to probe the neutrino mass splitting and mixing angle relevant for atmospheric neutrino oscillations. Models in which space-time has more than four dimensions have been examined for the unification of gauge couplings at high energies. A light intermediate scale in GUTS is a necessary ingredient for satisfying the re- quirement of proper leptogenesis. Obtaining such an intermediate scale is fraught with difficulties. It has been shown that within SUSY SO(10) GUTs this may be possible if the Higgs multiplets are appropriately chosen (16 rather than 126) and threshold corrections are incorporated. Alternate possibilities include the use of non-renormalisable Planck scale interactions and/or introduction of additional chiral multiplets. Publications: 1.
