  • Ghalsasi, Pallavi; Poswal, H. K.; Tripathi, Ravi; Garg, Nandini; Deo, M. N.; Sharma, Surinder M. (IOP Publishing, 2012)
    Recent discovery of colossal negative thermal expansion (NTE) behaviour in Silver Hexacyanocobaltate Ag3[Co(CN)6] has triggered interest among researchers to understand the basic mechanism causing such an unusual behaviour. ...
  • Khanna, Sakshum; Marathey, Priyanka; Utsav; Chaliyawala, Harsh; Mukhopadhyay, Indrajit (AIP Publishing, 2018-05)
    We present the studies on the structural properties of monolayer Bidisperse silica (SiO2) nanoparticles (BDS) on Silicon (Si-100) substrate using spin coating technique. The Bidisperse silica nanoparticle was synthesised ...
  • Sengupta, Anand (American Physical Society, 2016-10)
    The first observational run of the Advanced LIGO detectors, from September 12, 2015 to January 19, 2016, saw the first detections of gravitational waves from binary black hole mergers. In this paper, we present full results ...
  • Fairoos, C.; Ghosh, Avirup; Sarkar, Sudipta (American Physical Society, 2018-07)
    We study the entropy evolution of black holes in Lovelock gravity by formulating a thermodynamic generalization of the null Raychaudhuri equation. We show that the similarity between the expressions of entropy change of ...
  • Majumder, Barun (Springer Link, 2013-11)
    Here we study the effects of the Generalized Uncertainty Principle in the tunneling formalism for Hawking radiation to evaluate the quantum-corrected Hawking temperature and entropy for a Schwarzschild black hole. We compare ...
  • Sarkar, Sudipta (Springer, 2019-05)
    Black holes have often provided profound insights into the nature of gravity and the structure of space�time. The study of the mathematical properties of black objects is a major research theme of contemporary theoretical ...
  • Mishra, Akash K.; Rahman, Mostafizur; Sarkar, Sudipta (IOP Publishing, 2018-06)
    Hawking's topology theorem in general relativity restricts the cross-section of the event horizon of a black hole in 3+1 dimension to be either spherical or toroidal. The toroidal case is ruled out by the topology censorship ...
  • Bai, Rukmani; Bandyopadhyay, Soumik; Pal, Sukla; Suthar, K.; Angom, D. (American Physical Society, 2018-08)
    Quantum Hall (QH) states of two-dimensional (2D) single-layer optical lattices are examined using the Bose-Hubbard model (BHM) in the presence of an artificial gauge field. We study the QH states of both the homogeneous ...
  • Fairoos, C.; Ghosh, Avirup; Sarkar, Sudipta (World Scientific, 2018-10)
    The evolution of the black-hole horizon can be effectively captured by a fictitious membrane fluid living on the stretched horizon. We show that the dynamics of this boundary matter arises from the invariance of the bulk ...
  • Anand, Sampurn; Chaubal, Prakrut; Mazumdar, Arindam; Mohanty, Subhendra; Parashari, Priyank (IOP Publishing, 2018-05)
    Effective field theoretic description of dark matter fluid on large scales predicts viscosity of the order 10−6 H0 MP2. Recently, it has been shown that the same magnitude of viscosity can resolve the discordance between ...
  • Kurian, Manu; Chandra, Vinod (American Physical Society, 2018-06)
    The bulk viscosity of hot QCD medium has been obtained in the presence of strong magnetic field. The present investigation involves the estimation of the quark damping rate and subsequently the thermal relaxation time for ...
  • Singha, Pracheta; Abhishek, Aman; Kadam, Guruprasad; Ghosh, Sabyasachi; Mishra, Hiranmaya (IOP, 2019)
    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 ...
  • Gaur, G. (American Physical Society, 2017-03)
    In Advanced LIGO, detection and astrophysical source parameter estimation of the binary black hole merger GW150914 requires a calibrated estimate of the gravitational-wave strain sensed by the detectors. Producing an ...
  • Deepthi, K. N.; Goswami, Srubabati; Nath, Newton (American Physical Society, 2017-10)
    We study the effect of nonstandard interactions (NSIs) on the propagation of neutrinos through the Earth's matter and how it affects the hierarchy sensitivity of the DUNE experiment. We emphasize the special case when the ...
  • Suthar, Kuldeep; Angom, D. (American Physical Society, 2017-04)
    We study two-species Bose-Einstein condensates confined in quasi-two-dimensional (quasi-2D) optical lattices at finite temperatures, employing the Hartree-Fock-Bogoliubov theory with the Popov approximation. We examine the ...
  • Sengupta, Anand (IOP, 2015-05)
    In 2009–2010, the Laser Interferometer Gravitational-Wave Observatory (LIGO) operated together with international partners Virgo and GEO600 as a network to search for gravitational waves (GWs) of astrophysical origin. The ...
  • Dey, Krishna Kanti; Sen, Ayusman (American chemical society, 2017-05)
    Self-propelled, synthetic active matters that transduce chemical energy into mechanical motion are examples of biomimetic non-equilibrium systems. They are of great current interest, with potential applications in ...
  • Anand, Sampurn; Bhatt, Jitesh R.; Pandey, Arun Kumar (IOP Publishing, 2017-07)
    We study the generation and evolution of magnetic field in the presence of chiral imbalance and gravitational anomaly which gives an additional contribution to the vortical current. The contribution due to gravitational ...
  • Abhishek, Aman; Mishra, Hiranmaya (American Physical Society, 2019-03)
    We investigate the vacuum structure of dense quark matter in strong magnetic fields in a three-flavor Nambu Jona Lasinio (NJL) model including the Kobayashi-Maskawa-t�Hooft (KMT) determinant term using a variational method. ...
  • Mondal, Tanmoy; Basak, Tanushree (Science Direct, 2015-05)
    Recently the study of anomalous gamma-ray emission in the regions surrounding the galactic center has drawn a lot of attention as it points out that the excess of ∼1–3 GeV∼1–3 GeV gamma-ray in the low latitude is consistent ...
