  The electric charge transport in a weakly magnetized hot QCD medium has been investigated in the presence of an external inhomogeneous electric field. The current densities induced by the inhomogeneous electric field have ...
• Flavour specific neutrino self-interaction: H0 tension and IceCube 

  Mazumdar, Arindam; Mohanty, Subhendra; Parashari, Priyank (Cornell University Library, 2020-11)

  Self interaction in the active neutrinos is studied in the literature to alleviate the H0 tension. Similar self-interaction can also explain the observed dips in the flux of the neutrinos, coming from the distant astro-physical ...
• The 2HDM doppelganger 

  Coleppa, Baradhwaj; Sarkar, Agnivo (Cornell University Library, 2020-11)

  We discuss the structure of a model with an extended gauge symmetry group SU(2)�SU(2)�U(1) with a correspondingly rich Electroweak Symmetry Breaking structure. In spite of the additional scalar degrees of freedom in the ...
• The SPIIR online coherent pipeline to search for gravitational waves from compact binary coalescences 

  Sengupta, Anand S. et al. (Cornell University Library, 2020-11)

  This paper presents the SPIIR pipeline used for public alerts during the third advanced LIGO and Virgo run (O3 run). The SPIIR pipeline uses infinite impulse response (IIR) to perform zero-latency template filtering and ...
• The nonlinearity of interactions drives networks of neural oscillators to decoherence at strong coupling 

  Tripathi, Richa; Menon, Shakti N.; Sinha, Sitabhra (Cornell University Library, 2020-10)

  While phase oscillators are often used to model neuronal populations, in contrast to the Kuramoto paradigm, strong interactions between brain areas can be associated with loss of synchrony. Using networks of coupled ...
• Scalar perturbations of black holes in Jackiw-Teitelboim gravity 

  Bhattacharjee, Srijit; Sarkar, Subhodeep; Bhattacharyya, Arpan (Cornell University Library, 2020-11)
• Evolution of three-dimensional coherent structures in hall magnetohydrodynamics 

  Bora, Kamlesh; Bhattacharyya, Ramit; Smolarkiewicz, Piotr K. (Cornell University Library, 2020-11)

  The work extends the computational model EULAG-MHD to include Hall magnetohydrodynamics (HMHD)---important to explore physical systems undergoing fast magnetic reconnection at the order of the ion inertial length scale. ...
• Complexity from the reduced density matrix: a new diagnostic for chaos 

  Bhattacharyya, Arpan; Haque, S. Shajidul; Kim, Eugene H. (Cornell University Library, 2020-11)

  We investigate circuit complexity to characterize chaos in multiparticle quantum systems; concomitantly, we take strides in using complexity to characterize open quantum systems. By exploring different types of quantum ...
• Automating the inclusion of subthreshold signal-to-noise ratios for rapid gravitational-wave localization 

  Reza, Amit et al. (Cornell University Library, 2020-11)
• Displacement memory effect near the horizon of black holes 

  Bhattacharjee, Srijit; Kumar, Shailesh; Bhattacharyya, Arpan (Cornell University Library, 2020-11)

  We study the displacement memory effect and its connection with the extended-BMS symmetries near the horizon of black holes. Considering the near-horizon asymptotic metrics, we show there is a permanent shift in the geodesic ...
• New insights in the HII region G18.88-0.49: hub-filament system and accreting filaments 

  Dewangan, L. K.; Ojha, D. K.; Sharma, Saurabh; Del Palacio, S.; Bhadari, Naval Kishor; Das, A. (Cornell University Library, 2020-09)
• Learning from the crisis: public investment in research and development in the neoliberal regime in India 

  Bhattacharya, Soham; Sarkar, Agnivo (Munich University Library, 2020-10)

  This note brings out two inherent crises of research and development funding in contemporary India. We identified the ways in which current global neoliberal regime restricts the potential of research and development in ...
• Implications of the NANOGrav result on primordial gravitational waves in nonstandard cosmologies 

  Bhattacharyya, Sukannya; Mohanty, Subhendra; Parashari, Priyank (Cornell University Library, 2020-10)

  Recently, the NANOGrav collaboration has reported the evidence for a common-spectrum stochastic process, which might be interpreted as the first ever detection of stochastic gravitational wave (GW) background. We discuss ...

• Black hole zeroth law in higher curvature gravity 

  Ghosh, Rajes; Sarkar, Sudipta (Cornell University Library, 2020-09)

  The zeroth law of black hole mechanics is an assertion of constancy of the surface gravity on a stationary Killing horizon. The Hawking temperature of the black hole horizon is proportional to the surface gravity. Therefore, ...
