  • 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 ...
  • Bhattacharyya, Arpan et al. (American Physical Society, 2020-01)
    We propose a new diagnostic for quantum chaos. We show that the time evolution of complexity for a particular type of target state can provide equivalent information about the classical Lyapunov exponent and scrambling ...
  • 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 ...
  • Coleppa, Baradhwaj; Sarkar, Agnivo; Rai, Santosh Kumar (American Physical Society, 2020-03)
    We study the discovery prospects of the charged Higgs boson in the context of multi-Higgs models in certain beyond the Standard Model scenarios. We classify models into three categories based on the charged Higgs coupling ...
  • 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 ...
  • Das, Arpan; Kumar, Deepak; Mishra,Hiranmaya (American Physical Society, 2019-11)
  • 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 ...
  • Sinha, Kanupriya; Venkatesh, B. Prasanna; Meystre, Pierre (American Physical Society, 2018-11)
  • Jamal, M. Yousuf; Mitra, Sukanya; Chandra, Vinod (American Physical Society, 2017-05)
    Collective excitations of a hot QCD medium are the main focus of this article. The analysis is performed within semiclassical transport theory with isotropic and anisotropic momentum distribution functions for the gluonic ...
