Coronal turbulence and the angular broadening of radio sources - the role of the structure function
M. Ingale, P. Subramanian, Iver Cairns
The amplitude of density turbulence in the extended solar corona, especially near the dissipation scale, impinges on several problems of current interest. Radio sources observed th…
Marginalization for rare event simulation in switching diffusions
Anindya Goswami, François Le Gland
In this paper we use splitting technique to estimate the probability of hitting a rare but critical set by the continuous component of a switching diffusion. Instead of following c…
Heirarchical Self Assembly: Self Organized nano-structures in a nematically ordered matrix of self assembled polymeric chains
Shaikh Mubeena, Apratim Chatterji
We report many different nano-structures which are formed when model nano-particles of different sizes (diameter σ n ) are allowed to aggregate in a background matrix of semi-flexi…
Precise determination of the mass of the Higgs boson and tests of compatibility of its couplings with the standard model predictions using proton collisions at 7 and 8 TeV
CMS Collaboration
Properties of the Higgs boson with mass near 125 GeV are measured in proton-proton collisions with the CMS experiment at the LHC. Comprehensive sets of production and decay measure…
Entanglement entropy in Galilean conformal field theories and flat holography
Arjun Bagchi, Rudranil Basu, Daniel Grumiller +1
We present the analytical calculation of entanglement entropy for a class of two dimensional field theories governed by the symmetries of the Galilean conformal algebra, thus provi…
Effect of data gaps on correlation dimension computed from light curves of variable stars
Sandip V. George, G. Ambika, R. Misra
Observational data, especially astrophysical data, is often limited by gaps in data that arises due to lack of observations for a variety of reasons. Such inadvertent gaps are usua…
Designing Frustrated Quantum Magnets with Laser-Dressed Rydberg Atoms
Alexander W. Glaetzle, Marcello Dalmonte, Rejish Nath +3
We show how a broad class of lattice spin-1/2 models with angular- and distance-dependent couplings can be realized with cold alkali atoms stored in optical or magnetic trap arrays…
Complex networks with scale-free nature and hierarchical modularity
Snehal M. Shekatkar, G. Ambika
Generative mechanisms which lead to empirically observed structure of networked systems from diverse fields like biology, technology and social sciences form a very important part…
Schwinger Effect and Negative Differential Conductivity in Holographic Models
Shankhadeep Chakrabortty, B. Sathiapalan
The consequences of the Schwinger effect for conductivity is computed for strong coupling systems using holography. The one loop diagram on the flavor brane introduces an $O({λ\ove…
Elliptic Waves in Two Component Long Wave--Short Wave Resonance Interaction System in One and Two dimensions
Avinash Khare, T. Kanna, K. Tamilselvan
We consider (2+1) and (1+1) dimensional long-wave short-wave resonance interaction systems. We construct an extensive set of exact periodic solutions of these systems in terms of L…
Gaussian elimination in unitary groups with an application to cryptography
Ayan Mahalanobis, Anupam Singh
Gaussian elimination is used in special linear groups to solve the word problem. In this paper, we extend Gaussian elimination to unitary groups. These algorithms have an applicati…
Magnetism in stoichiometric and off-stoichiometric MnO clusters: Insights from {\it ab initio} theory
Shreemoyee Ganguly, Mukul Kabir, Carmine Autieri +1
We study the composition dependent evolution of geometric and magnetic structures of MnO clusters within density functional theory. A systematic and extensive search through the po…
Flat space cosmologies in two dimensions - Phase transitions and asymptotic mass-domination
Arjun Bagchi, Daniel Grumiller, Jakob Salzer +2
We study flat space cosmologies in two dimensions by taking the flat space limit of the Achucarro-Ortiz model. We unravel a phase transition between hot flat space and flat space c…
The optimal hedging in a semi-Markov modulated market
Anindya Goswami, Jeeten Patel, Poorva Sevgaonkar
This paper includes an original self contained proof of well-posedness of an initial-boundary value problem involving a non-local parabolic PDE which naturally arises in the study…
Bose-Einstein Condensation in an electro-pneumatically transformed quadrupole-Ioffe magnetic trap
Sunil Kumar, Sumit Sarkar, Gunjan Verma +3
We report a novel approach for preparing a Bose-Einstein condensate (BEC) of Rb atoms using electro-pneumatically driven transfer of atoms into a Quadrupole-Ioffe magnetic t…
A study of density modulation index in the inner heliospheric solar wind during solar cycle 23
Susanta Kumar Bisoi, P. Janardhan, M. Ingale +4
The ratio of the rms electron density fluctuations to the background density in the solar wind (density modulation index, ) is of vital importance in understan…
Benford Analysis: A useful paradigm for spectroscopic analysis
Gaurav Bhole, Abhishek Shukla, T. S. Mahesh
Benford's law is a statistical inference to predict the frequency of significant digits in naturally occurring numerical databases. In such databases this law predicts a higher occ…
On the welded Tube map
Benjamin Audoux
This note investigates the so-called Tube map which connects welded knots, that is a quotient of the virtual knot theory, to ribbon torus-knots, that is a restricted notion of fill…
Galilean Conformal Electrodynamics
Arjun Bagchi, Rudranil Basu, Aditya Mehra
Maxwell's Electrodynamics admits two distinct Galilean limits called the Electric and Magnetic limits. We show that the equations of motion in both these limits are invariant under…
