Low frequency observations of SN 1993J with Giant Meterwave Radio Telescope
P. Chandra, A. Ray, S. Bhatnagar
In this paper, we discuss the low frequency spectrum of SN 1993J with GMRT. We observed SN 1993J at several epochs in 20cm, 50cm, 90cm and 125cm wavelengths and achieved near simul…
Comment on "Triplet-to-Singlet Exciton Formation in poly(p-phenylene-vinylene) Light-Emitting Diodes"
S. Mazumdar, Mousumi Das, S. Ramasesha
The low-lying singlet and triplet spectrum in conjugated polymers clearly show that the mechanism proposed by Lin et al. to explain their electric field dependence of singlet to tr…
Ferroelectric YMnO3 films deposited on n-type Si (111) substrates
S. Parashar, A. R. Raju P. Victor, S. B. Krupanidhi +1
YMnO3 thin films have been grown on n - type Si substrates by nebulized spray pyrolysis in the Metal - Ferroelectric - Semiconductor (MFS) configuration. The C-V characteristics of…
Characterization of the Energy Structure and Adiabatic Magnetization Process of V15
Indranil Rudra, K. Saito, S. Ramasesha +1
The energy structure of the V is studied using exact diagonalization methods, and the adiabatic changes of the magnetization in the system with the sweeping field are invest…
Spiral Turbulence: From the Oxidation of CO on Pt(110) to Ventricular Fibrillation
Ashwin Pande, Sitabhra Sinha, Rahul Pandit
We give a brief overview of systems that show spiral patterns and spatiotemporally chaotic states. We concentrate on two physical systems: (1) the oxidation of CO on Pt(110) and (2…
Linear Polarisation Properties of Pulsars at 35 & 327 MHz
Ashish Asgekar, A. A. Deshpande
We report preliminary results of our study of linear polarization in the pulsar emission at 35 & 327 MHz. We have exploited for this purpose the spectral modulation resulting from…
