Cold HI in faint dwarf galaxies
Narendra Nath Patra, Jayaram N. Chengalur, Igor D. Karachentsev +2
We present the results of a study of the amount and distribution of cold atomic gas, as well its correlation with recent star formation in a sample of extremely faint dwarf irregul…
Andromeda IV, a solitary gas-rich dwarf galaxy
I. D. Karachentsev, Jayaram. N. Chengalur, R. B. Tully +4
Observations are presented of the isolated dwarf irregular galaxy And IV made with the Hubble Space Telescope Advanced Camera for Surveys and the Giant Metrewave Radio Telescope in…
Distribution of Bell inequality violation vs. multiparty quantum correlation measures
Kunal Sharma, Tamoghna Das, Aditi Sen De +1
Violation of a Bell inequality guarantees the existence of quantum correlations in a quantum state. A pure bipartite quantum state, having nonvanishing quantum correlation, always…
Insights into the evolution of symbiotic recurrent novae from radio synchrotron emission: V745 Scorpii and RS Ophiuchi
N. G. Kantharia, Prasun Dutta, Nirupam Roy +6
We present observations at 610 MHz and 235 MHz using the Giant Metrewave Radio Telescope (GMRT) of the recurrent nova V745 Scorpii which recorded its last outburst on 6 February 20…
Electronic topological transitions in Cd at high pressures
Varadharajan Srinivasan, B. K. Godwal, Jeffrey C. Grossman +1
Pressure-induced changes in the Fermi surface of Cd up to 40 GPa are studied using highly accurate density-functional theory calculations. The topology of Fermi surface changes at…
Phase Space Distribution for Two-Gap Solution in Unitary Matrix Model
Parikshit Dutta, Suvankar Dutta
We analyze the dynamics of weakly coupled finite temperature gauge theories on by studying a class of effective unitary matrix model. Solving Dyson-Schwinger equation…
First observation of temperature dependent lightinduced response of Ge25As10Se65 thin films
Pritam Khan, Rituraj Sharma, Uday Deshpande +1
Ge rich ternary chalcogenide glasses (ChG) exhibit photobleaching (PB) when illuminated with bandgap light and such an effect is originating from the combined effect of intrinsic s…
Null Fluids - A New Viewpoint of Galilean Fluids
Nabamita Banerjee, Suvankar Dutta, Akash Jain
This article is a detailed version of our short letter `On equilibrium partition function for non-relativistic fluid' [arXiv:1505.05677] extended to include an anomalous sym…
A Perturbative Analysis of Synchrotron Spectral Index Variation over Microwave Sky
Rajib Saha, Pavan Kumar Aluri
In this paper, we implement a perturbative approach, first proposed by Bouchet & Gispert (1999), to estimate variation of spectral index of galactic polarized synchrotron emission,…
Origin of lowered magnetic moments in epitaxially strained thin films of multiferroic BiFeCrO
Paresh Chandra Rout, Aditya Putatunda, Varadharajan Srinivasan
We have investigated the effect of epitaxial strain on the magnetic properties and -site cation ordering in multiferroic BiFeCrO (001) thin films using a density-functio…
Probing the superconducting ground state of the rare-earth ternary boride superconductors RuB ( = Lu,Y) using muon-spin rotation and relaxation
Joel A. T. Barker, Ravi P. Singh, Adrian D. Hillier +1
The superconductivity in the rare-earth transition metal ternary borides RuB (where = Lu and Y) has been investigated using muon-spin rotation and relaxation. Measuremen…
Breakdown of electron-pairs in the presence of an electric field of a superconducting ring
Bradraj Pandey, Sudipta Dutta, Swapan K. Pati
The quantum dynamics of quasi-one-dimensional ring with varying electron filling factor is investigated in presence of external electric field. The system is modeled within Hubbard…
Representations of the dimensional quantum torus
Ashish Gupta
The -dimensional quantum torus is defined as the associative -algebra generated by together with their inverses sati…
Equilibrium partition function for nonrelativistic fluids
Nabamita Banerjee, Suvankar Dutta, Akash Jain
We construct an equilibrium partition function for a non-relativistic fluid and use it to constrain the dynamics of the system. The construction is based on light cone reduction, w…
Visibility moments and power spectrum of turbulence velocity
Prasun Dutta
Here we introduce moments of visibility function and discuss how those can be used to estimate the power spectrum of the turbulent velocity of external spiral galaxies. We perform…
Effect of turbulent velocity on the \HI intensity fluctuation power spectrum from spiral galaxies
Prasun Dutta
We use numerical simulations to investigate effect of turbulent velocity on the power spectrum of \HI intensity from external galaxies when (a) all emission is considered, (b) emis…
Curvature Singularity in f(R) Theories of Gravity
Koushik Dutta, Sukanta Panda, Avani Patel
Although modification of late time cosmology is successful in explaining present cosmic acceleration, it is difficult to satisfy the fifth-force constraint simultaneously. E…
