We trace the evolution of Indian physics community from 1919 to 2013 by analyzing the co-authorship network constructed from papers published by authors in India in American Physical Society (APS) journals. We make inferences ...

On August 17, 2017, the Advanced LIGO and Advanced Virgo gravitational-wave detectors observed a low-mass compact binary inspiral. The initial sky localization of the source of the gravitational-wave signal, GW170817, ...
The Eddington-inspired Born-Infeld (EiBI) gravity is a modification of the theory of general relativity inspired by the nonlinear Born-Infeld electrodynamics. The theory is described by a series of higher-curvature terms ...

It has long been an aspirational goal to create artificial structures that allow fast
permeation of water but reject even the smallest hydrated ions, replicating the feat
achieved by nature in protein channels (e.g., ...

We present a multi-messenger measurement of the Hubble constant H_0 using the binary-black-hole merger GW170814 as a standard siren, combined with a photometric redshift catalog from the Dark Energy Survey (DES). The ...
The one loop self energy of the neutral rho meson is obtained for the effective ρππ and ρNN interaction at finite temperature and density in presence of a constant background magnetic field of arbitrary strength. In our ...
One of the recent interests in high energy physics is to study the phase diagram of strongly interacting matter.QCD phase diagram has been studied extensively in the temperature (T) - baryon chemical potential (μB) plane ...

We describe directed searches for continuous gravitational waves from sixteen well localized candidate neutron stars assuming none of the stars has a binary companion. The searches were directed toward fifteen supernova ...
We study the rare decay B→K∗2(1430)(→Kπ)ℓ+ℓ− in the Standard Model and beyond. Working in the transversity basis, we exploit the relations between the heavy-to-light form factors in the limit of heavy quark (mb→∞) and large ...
We calculate the transport coefficients, drag and momentum diffusion, of a heavy quark in a thermalised plasma of light quarks in the background of Polyakov loop. Quark thermal mass and the gluon Debye mass are calculated ...

We present the first Advanced LIGO and Advanced Virgo search for ultracompact binary systems with component masses between 0.2 M⊙–1.0 M⊙ using data taken between September 12, 2015 and January 19, 2016. We find no viable ...
We have calculated different transport coefficients such as shear, bulk viscosities and electrical conductivity of quark and hadronic matter within the framework of a 2 flavor Polyakov-quark–meson model. For constant thermal ...
