  • Dynamics of hot QCD matter - current status and developments 
    Chandra, Vinod; Gowthama K. K.; Kurian, Manu et al. (Cornell University Library, 2022-08)
    The discovery and characterization of hot and dense QCD matter, known as Quark Gluon Plasma (QGP), remains the most international collaborative effort and synergy between theorists and experimentalists in modern nuclear ...
  • Dynamical love for area quantized black holes 
    Nair, Sreejith; Chakraborty, Sumanta; Sarkar, Sudipta (Cornell University Library, 2022-08)
    We show that the area-quantized black holes have non-zero dynamical tidal Love numbers for frequencies differing from the characteristic frequencies associated with the quantization spectrum. Intriguingly, the details of ...

    We have reviewed the first year of observations of the Solar X-ray Monitor (XSM) onboard Chandrayaan-2, and the available multi-wavelength observations to complement the XSM data, focusing on Solar Dynamics Observatory AIA ...
  • Crystalline phases of laser-driven dipolar Bose-Einstein condensates 
    Mishra, Chinmayee; Ostermann, Stefan; Mivehvar, Farokh; Venkatesh, B. Prasanna (Cornell University Library, 2022-07)
    Although crystallization is a ubiquitous phenomenon in nature, crystal formation and melting still remain fascinating processes with several open questions yet to be addressed. In this work, we study the emergent crystallization ...
  • Analytical study of gravitational lensing in Kerr-Newman black-bounce spacetime 
    Ghosh, Saptaswa; Bhattacharyya, Arpan (Cornell University Library, 2022-01)
    We investigate the equatorial deflection angle of light rays propagating in Kerr-Newman black-bounce spacetime. Furthermore, we analyze the light ray trajectories and derive a closed-form formula for deflection angle in ...
  • Thermally corrected masses and freeze-in dark matter: a case study 
    Chakrabarty, Nabarun; Konar, Partha; Roshan, Rishav; Show, Sudipta (Cornell University Library, 2022-06)
    If coupled feebly to the Standard Model bath, dark matter can evade the severe constraints from the direct search experiments. At the same time, such interactions help produce dark matter via the freeze-in mechanism. The ...
  • CFT to BMS: complexity and OTOC 
    Banerjee, Aritra; Bhattacharyya, Arpan; Drashni, Priya; Pawar, Srinidhi (Cornell University Library, 2022-05)
    We probe the contraction from 2d relativistic CFTs to theories with Bondi-Metzner-Sachs(BMS) symmetries, or equivalently Conformal Carroll symmetries, using diagnostics of quantum chaos. Starting from an Ultrarelativistic ...
  • Thermal and thermoelectric responses of hot QCD medium in time-varying magnetic fields 
    Gowthama K. K.; Kurian, Manu; Chandra, Vinod (Cornell University Library, 2022-05)
    The thermal response of the hot QCD matter has been studied in the presence of a time-varying magnetic field. The impact of magnetic field, its time dependence, and the collision aspects of the medium on thermal transport ...
  • Echoes from braneworld wormholes 
    Biswas, Shauvik; Rahman, Mostafizur; Chakraborty, Sumanta (Cornell University Library, 2022-05)
    We have studied the stability of wormhole geometries, under massless scalar, electromagnetic and axial gravitational perturbations, in the context of higher dimensional spacetimes. Intriguingly, the construction of a ...
  • IRC-safe graph autoencoder for an unsupervised anomaly detection 
    Atkinson, Oliver; Bhardwaj, Akanksha; Englert, Christoph; Konar, Partha; Ngairangbam, Vishal S.; Spannowsky, Michael (Cornell University Library, 2022-04)
    Anomaly detection through employing machine learning techniques has emerged as a novel powerful tool in the search for new physics beyond the Standard Model. Historically similar to the development of jet observables, ...
  • Optimization of asymmetric quantum Otto engine cycles 
    Shastri, Rahul; Venkatesh, B. Prasanna (Cornell University Library, 2022-04)
    We consider the optimization of the work output and fluctuations of a finite-time quantum Otto heat engine cycle consisting of compression and expansion work strokes of unequal duration. The asymmetry of the cycle is ...
  • Light cone sum rules and form factors for p→e+γ 
    Bansal, Anshika; Mahajan, Namit (Cornell University Library, 2022-04)
    Proton decay is a baryon number violating process, and hence is forbidden in the Standard Model (SM) of particle physics. Baryon number violation is expected to be an important criteria to explain the matter-anti-matter ...
  • Absorption variability of the highly obscured active galactic nucleus NGC 4507 
    Jana, Arghajit; Ricci, Claudio; Naik, Sachindra; Tanimoto, Atsushi; Kumari, Neeraj; Chang, Hsiang-Kuang; Nandi, Prantik; Chatterjee, Arka; Safi-Harb, Samar (Cornell University Library, 2022-03)
    We present a detailed study of the highly obscured active galaxy NGC 4507, performed using four Nuclear Spectroscopic Telescope Array (NuSTAR) observations carried out between May and August in 2015 (~ 130 ks in total). ...
  • A study of eccentric binaries in Horndeski theory 
    Chowdhuri, Abhishek; Bhattacharyya, Arpan (Cornell University Library, 2022-03)
    We study the orbital evolution of eccentric binary systems in Horndeski theory. This particular theory provides a testbed to give insightful comparisons with data. We compute the rate of energy loss and the rate of change ...

    Saha, Madhumita; Venkatesh, B. Prasanna; Agarwalla, Bijay Kumar (Cornell University Library, 2022-02)

  • Complexity of warped conformal field theory 
    Bhattacharyya, Arpan; Katoch, Gaurav; Roy, Shubho R. (Cornell University Library, 2022-02)
    Warped conformal field theories in two dimensions are exotic nonlocal, Lorentz violating field theories characterized by Virasoro-Kac-Moody symmetries and have attracted a lot of attention as candidate boundary duals to ...

    Dutta, Manoranjan; Narendra, Nimmala; Sahu, Narendra; Shil, Sujay (Cornell University Library, 2022-02)
    The nature of neutrinos, whether Dirac or Majorana, is hitherto not known. Assuming that the neutrinos are Dirac, which needs B?L to be an exact symmetry, we make an attempt to explain the observed proportionality between ...

    Chakravarti, Kabir; Ghosh, Rajes; Sarkar, Sudipta (Cornell University Library, 2022-01)
    Recent gravitational wave observation based on the data from GW150914 has firmly confirmed Hawking's area theorem and estimated the increase in total horizon area during a merger process of two Kerr black holes. We use ...
  • The prospect of distinguishing astrophysical objects with LISA 
    Rahman, Mostafizur; Bhattacharyya, Arpan (Cornell University Library, 2021-12)
    The famous no-hair theorem dictates that the multipole moments of Kerr black holes depend only on their mass and angular momentum. Thus, the measurement of multipole moments of astrophysical objects through gravitational-wave ...
  • Signature of non-uniform area quantization on black hole echoes 
    Chakravarti, Kabir; Ghosh, Rajes; Sarkar, Sudipta (Cornell University, 2021-12)
