First order magnetic transition in CeFe alloys: Phase-coexistence and metastability
S. B. Roy, G. K. Perkins, M. K. Chattopadhyay +5
First order ferromagnetic (FM) to antiferromagnetic (AFM) phase transition in doped-CeFe alloys is studied with micro-Hall probe technique. Clear visual evidence of magnetic ph…
Search for Colour Singlet and Colour Reconnection Effects in Hadronic Z Decays at LEP
L3 Collaboration
A search is performed in symmetric 3-jet hadronic Z decay events for evidence of colour singlet production or colour reconnection effects. Asymmetries in the angular separation of…
Taylor expansions in chemical potential
Rajiv Gavai, Sourendu Gupta, Rajarshi Roy
Properties of QCD at finite chemical potential are extracted using Taylor series expansions. The continuum limits of lattice results are presented. The result of expanding the free…
Partial classification of modules for Lie-algebra of diffeomorphisms of d-dimensional torus
S. Eswara Rao
We consider the Lie-algebra of the group of diffeomorphisms of d-dimensional torus which is also known to be the algebra of derivations on a Laurent polynomial ring A in d commutin…
Rolling tachyon solution of two-dimensional string theory
Gautam Mandal, Spenta R. Wadia
We consider a classical (string) field theory of matrix model which was developed earlier in hep-th/9207011 and subsequent papers. This is a noncommutative field theory where…
Gravitational collapse from smooth initial data with vanishing radial pressure
Ashutosh Mahajan, Rituparno Goswami, Pankaj S. Joshi
We study here the spherical gravitational collapse assuming initial data to be necessarily smooth, as motivated by the requirements based on physical reasonableness. A tangential p…
Phase transitions in periodically driven macroscopic systems
Sreedhar B. Dutta
We study the large-time behavior of a class of periodically driven macroscopic systems. We find, for a certain range of the parameters of either the system or the driving fields, t…
The role of critical current on point contact Andreev Reflection spectrum between a normal metal and a superconductor
G. Sheet, S. Mukhopadhyay, P. Raychaudhuri
The point contact spectrum between a normal metal and a superconductor often shows unexpected sharp dips in the conductance at voltage values larger than the superconducting energy…
Periodicities In The X-Ray Intensity Variations of TV Columbae: An Intermediate Polar
V. R. Rana, K. P. Singh, E. M. Schlegel +1
We present results from a temporal analysis of the longest and the most sensitive X-ray observations of TV Columbae--an intermediate polar. The observations were carried out with t…
Identifying the Background Signal in ARPES of High Temperature Superconductors
A. Kaminski, S. Rosenkranz, H. M. Fretwell +9
One of the interesting features of the photoemission spectra of the high temperature cuprate superconductors is the presence of a large signal (referred to as the "background'') in…
Magnetic Ordering and Superconductivity in the REIrGe (RE = Y, La-Tm, Lu) System
Yogesh Singh
We find that the compounds for RE = Y, La-Dy, crystallize in the tetragonal Ibam (UCoSi type) structure whereas the compounds for RE = Er-Lu, crystallize in a new ortho…
X-ray and radio prompt emission from a hypernova SN 2002ap
P. Chandra, A. Ray, F. Sutaria
Here we report on combined X-ray and radio observations of SN 2002ap with XMM-Newton ToO observation and GMRT observations aided with VLA published results. In deriving the X-ray f…
Low frequency radio and X-ray properties of core-collapse supernovae
A. Ray, P. Chandra, F. Sutaria +1
Radio and X-ray studies of young supernovae probe the interaction between the supernova shock waves and the surrounding medium and give clues to the nature and past of the progenit…
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…
Signatures of supernova neutrino oscillations in the Earth mantle and core
A. S. Dighe, M. Kachelriess, G. G. Raffelt +1
The Earth matter effects on supernova (SN) neutrinos can be identified at a single detector through peaks in the Fourier transform of their ``inverse energy'' spectrum. The positio…
Photometric study of two novae in M31
Y. C. Joshi, A. K. Pandey, D. Narasimha +3
We report light curves of 2 novae in the M31 galaxy which were detected in the four year Nainital Microlensing Survey. One of these novae has been tracked from the initial…
A study of the Galactic star forming region IRAS 02593+6016 / S 201 in infrared and radio wavelengths
D. K. Ojha, S. K. Ghosh, V. K. Kulkarni +3
We present infrared and radio continuum observations of S 201 star forming region. A massive star cluster is observed in this region, which contains different classes of young stel…
Resonant slepton production at the LHC in models with an ultralight gravitino
B. C. Allanach, Manoranjan Guchait, K. Sridhar
We examine resonant slepton production at the LHC with gravitinos in the final state. The slepton undergoes gauge decay into a neutralino and a lepton, the neutralino decays into a…
