  • Template bank to search for exotic gravitational wave signals from astrophysical compact binaries 
    Sharma, Abhishek; Roy, Soumen; Sengupta, Anand S. (Cornell University Library, 2023-11)
    Modeled searches of gravitational wave signals from compact binary mergers rely on template waveforms determined by the theory of general relativity (GR). Once a signal is detected, one generally performs the model agnostic ...

    Chakravarti, Kabir; Ghosh, Rajes; Sarkar, Sudipta (Cornell University Library, 2023-10)
    We investigate the ergoregion instability of area-quantized rotating quantum black holes (QBH) under gravitational perturbation. We show that the instability can be avoided in binary systems that include QBHs if the ...

    Gubernari, Nico; Khodjamirian, Alexander; Mandal, Rusa; Mannel, Thomas (Cornell University Library, 2023-09)
    We present the first application of QCD light-cone sum rules (LCSRs) with B(s)-meson distribution amplitudes to the B(s) D (s)0 form factors, where D(s)0 is a charmed scalar meson. We consider two scenarios for the D0 ...

    The number of gravitational wave signals from the merger of compact binary systems detected in the network of advanced LIGO and Virgo detectors is expected to increase considerably in the upcoming science runs. Once a ...
  • Collective excitations of a hot QCD medium in a time dependent background magnetic field 
    Gowthama, K. K.; Chandra, Vinod (Cornell University Library, 2023-09)
    Collective modes within a hot Quantum Chromodynamics (QCD) medium are obtained from the polarization tensor, considering both constant and time-varying electromagnetic fields. In both scenarios, five complex modes emerge, ...

    Rawat, Ananya; Gupta, Girjesh (Cornell University Library, 2023-09)
    Coronal fan loops rooted in sunspot umbra show outward propagating waves with subsonic phase speed and period around 3-min. However, their source region in the lower atmosphere is still ambiguous. We performed multi-wavelength ...
  • Controlling work output and coherence in finite time quantum otto engines through monitoring 
    Shastri, Rahul; Venkatesh, B. Prasanna (Cornell University Library, 2023-08)
    We examine the role of diagnostic quantum measurements on the work statistics of a finite-time quantum Otto heat engine operated in the steady-state. We consider three pointer-based measurement schemes that differ in the ...

    India's third Moon mission Chandrayaan 3 will deploy a lander and a rover at a high latitude location of the Moon enabling us to carry out first ever in-situ science investigations of such a pristine location that will ...
  • Constraining inverse moment of B-meson distribution amplitude using Lattice QCD data 
    Mandal, Rusa; Nandi, Soumitra; Ray, Ipsita (Cornell University Library, 2023-08)
    We constrain the inverse moment of the B-meson light-cone distribution amplitude (LCDA), lambda B in heavy quark effective theory, using form factor estimates from Lattice QCD collaboration. The estimation of the parameter ...
  • Sensitivity to CP discovery in the presence of Lorentz invariance violating potential at T2HK/T2HKK 
    Chakraborty, Kaustav; Goswami, Srubabati; Pan, Supriya (Cornell University Library, 2023-08)
    Investigation of conservation/violation of CP symmetry in the leptonic sector is very essential in understanding the evolution of the universe. Lorentz invariance and CPT are fundamental symmetries of nature. The violation ...
  • CFT reconstruction of local bulk operators in half-Minkowski space 
    Bhattacharyya, Arpan; Dogra, Manas; Roy, Shubho R. (Cornell University Library, 2023-08)
    We construct a holographic map that reconstructs massless fields (scalars, Maxwell field \& Fierz-Pauli field) in half-Minkowski spacetime in d+1 dimensions terms of smeared primary operators in a large N factorizable CFT ...
