    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, ...
  • Worldline effective field theory of inspiralling black hole binaries in presence of dark photon and axionic dark matter 
    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 ...
  • Free space continuous variable quantum key distribution with discrete phases 
    Rani, Anju; Chandravanshi, Pooja; Ramakrishnan, Jayanth; Vaity, Pravin; Madhusudhan, P.; Sharma, Tanya; Bhardwaj, Pranav; Biswas, Ayan; Singh, R. P. (Cornell University Library, 2023-05)
    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)
    We introduce an optimization technique to discriminate signal and background in any phenomenological study based on the cut and count-based method. The core ideas behind this algorithm is the introduction of a ranking ...
  • Quantum state complexity meets many-body scars 
    Nandy, Sourav; Mukherjee, Bhaskar; Bhattacharyya, Arpan; Banerjee, Aritra (Cornell University Library, 2023-05)
    Scar eigenstates in a many-body system refers to a small subset of non-thermal finite energy density eigenstates embedded into an otherwise thermal spectrum. This novel non-thermal behaviour has been seen in recent experiments ...
  • Test of new physics effects in B¯→(D(∗),π)ℓ-ν¯ℓ decays with heavy and light leptons 
    Ray, Ipsita; Nandi, Soumitra (Cornell University Library, 2023-05)
    We study the B¯→D(D∗)ℓ-ν¯ℓ decays based on the up-to-date available inputs from experiments and the lattice. First, we review the standard model (SM) predictions of the different observables associated with these decay ...
  • Traversable wormholes in bi-metric gravity 
    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 ...
  • On the propagation of gravity waves in the lower solar atmosphere in different magnetic configurations 
    Kumar, Hirdesh; Kumar, Brajesh; Rajaguru, S. P. (Cornell University Library, 2023-05)
    Gravity waves are generated by turbulent subsurface convection overshooting or penetrating locally into a stably stratified medium. While propagating energy upwards, their characteristic negative phase shift over height ...
  • Activity induced diffusion recovery in crowded colloidal suspension 
    Maiti, Arnab; Koyano, Yuki; Kitahata, Hiroyuki; Dey, Krishna Kanti (Cornell University Library, 2023-05)
    We show that the force generated by active enzyme molecules are strong enough to influence the dynamics of their surroundings under artificial crowded environments. We measured the behavior of polymer microparticles in a ...

    Sarkar, Subhodeep; Rahman, Mostafizur; Chakraborty, Sumanta (Cornell University Library, 2023-04)

    Singh, Sandeep; Kumar, Vimlesh; Sharma, Varun; Faccio, Daniele; Samanta, G. K. (Cornell University Library, 2023-04)
    Hong-Ou-Mandel (HOM) interference, bunching of two indistinguishable photons on a balanced beam-splitter, has emerged as a promising tool for quantum sensing. The interference dip-width, thus the spectral-bandwidth of ...
