    Ghosh, Rajes; Sk, Selim; Sarkar, Sudipta (Cornell University Library, 2023-06)
    Several hairy black hole solutions are known to violate the original version of the celebrated no-hair conjecture. This prompted the development of a new theorem that establishes a universal lower bound on the extension ...

    We study Krylov complexity of a one-dimensional Bosonic system, the celebrated Bose-Hubbard Model. The Bose-Hubbard Hamiltonian consists of interacting bosons on a lattice, describing ultra-cold atoms. Apart from showing ...
  • Heavy quark radiation in an anisotropic hot QCD medium 
    Prakash, Jai; Chandra, Vinod; Das, Santosh K. (Cornell University Library, 2023-06)
    The impact of momentum anisotropy on the heavy quarks (HQs) dynamics has been investigated in a hot QCD medium while considering both collisional and radiative processes within the ambit of the Fokker-Planck approach. The ...

    Mohapatra, Vivekanand; J., Johnny; Natwariya, Pravin Kumar; Goswami, Jishnu; Nayak, Alekha C. (Cornell University, 2023-06)
    Understanding the astrophysical nature of the first stars still remains an unsolved problem in cosmology. The redshifted global 21-cm signal and power spectrum act as a treasure trove to probe the Cosmic Dawn era -- when ...
  • Hawking radiation from stationary black holes using gravitational anomaly 
    Sk, Selim; Sarkar, Sudipta (Cornell University, 2023-06)
    Among all the different techniques to derive the Hawking effect, the approach based on gravitational anomaly by Robinson and Wilczek provides a simple and satisfactory origin of the black hole radiation. In this picture, ...

    Bhattacharyya, Arpan; Ghosh, Saptaswa; Pal, Sounak (Cornell University Library, 2023-05)
    We investigate the correction to the potential that gives rise to the bound orbits and radiation from non-spinning inspiralling binary black holes in a dark matter environment consisting of axion-like particles and dark ...

    Quantum Key Distribution (QKD) offers unconditional security in principle. Many QKD protocols have been proposed and demonstrated to ensure secure communication between two authenticated users. Continuous variable (CV) QKD ...
  • Optimizing the cut and count method in phenomenological studies 
    Coleppa, Baradhwaj; Krishna, Gokul B.; Sarkar, Agnivo; Shil, Sujay (Cornell University Library, 2023-05)

  • Quantum state complexity meets many-body scars 
    Nandy, Sourav; Mukherjee, Bhaskar; Bhattacharyya, Arpan; Banerjee, Aritra (Cornell University Library, 2023-05)

    Rahman, Mostafizur; Sen, Anjan A.; Bohra, Sunil Singh (Cornell University Library, 2023-05)
    The ghost-free bi-metric gravity theory is a viable theory of gravity that explores the interaction between a massless and a massive graviton and can be described in terms of two dynamical metrics. In this paper, we present ...
