  • 21 cm line astronomy and constraining new physics 
    Natwariya, Pravin Kumar (Cornell University Library, 2023-01)
    The 21 cm signal appears to be a treasure trove to provide an insight into the period when the first generation of luminous objects formed in the Universe. Hydrogen is the predominating fraction of the total baryonic matter ...
  • The 2HDM doppelganger 
    Coleppa, Baradhwaj; Sarkar, Agnivo (Cornell University Library, 2020-11)
    We discuss the structure of a model with an extended gauge symmetry group SU(2)�SU(2)�U(1) with a correspondingly rich Electroweak Symmetry Breaking structure. In spite of the additional scalar degrees of freedom in the ...
  • 331 models and grand unification: from minimal SU(5) to minimal SU(6) 
    Deppisch, Frank F.; Hati, Chandan; Patra, Sudhanwa; Sarkar, Utpal; Valle, Jose W. F. (Cornell University Library, 2016-08)
    We consider the possibility of grand unification of the SU(3)c⊗SU(3)L⊗U(1)X model in an SU(6) gauge unification group. Two possibilities arise. Unlike other conventional grand unified theories, in SU(6) one can embed the ...
  • 3D N = 1 supergravity from Virasoro TQFT: gravitational partition function and out-of-time-order correlator 
    Bhattacharyya, Arpan; Ghosh, Saptaswa; Nandi, Poulami; Pal, Sounak (Cornell University Library, 2024-08)
    In this paper, we compute the partition functions of N=1 SUGRA for different boundary topologies, i.e. sphere and torus, using super-Virasoro TQFT. We use fusion and modular kernels of the super-Liouville theory to compute ...
  • 3HDM at the ILC 
    Coleppa, Baradhwaj; Khanna, Akshat; Krishna, Gokul B. (Cornell University Library, 2025-06)
  • 750 GeV resonance in the dark left-right model 
    Dey, Ujjal Kumar; Mohanty, Subhendra; Tomar, Gaurav (Cornell University Library, 2015-12)
    We explain the 750 GeV diphoton resonance in the context of the dark left-right symmetric model. A global symmetry in this model, stabilizes the dark matter and ensures that the scalar couples only to gluons and photons. ...
  • A geometric-analytic proof of the reverse isoperimetric inequality 
    Kumar, Naman (MDPI, 2025-06)
    We present the first geometric-analytic proof of the reverse isoperimetric inequality for black holes in any dimension. The proof holds for compact Riemannian hypersurfaces in AdS (and dS) and seems to be a generic property ...
  • A Modular PyTheus quantum network interpreter: automated analysis and visualization of optimized quantum architectures 
    Sreekantham, Rithvik Kumar (Cornell University Library, 2025-07)
    We present a modular interpreter for PyTheus-optimized quantum networks that automatically analyzes and visualizes complex quantum architectures discovered through automated optimization. The interpreter addresses the ...
  • A proof of the reverse isoperimetric inequality using a geometric-analytic approach 
    Kumar, Naman (MDPI, 2025-07)
    We present the first proof of the reverse isoperimetric inequality for black holes in arbitrary dimension using a two-pronged geometric-analytic approach. The proof holds for compact Riemannian hypersurfaces in AdS space ...
  • A theory of gravity in Minkowski space 
    Kumar, Naman (MDPI, 2024-09)
    In this paper, we present a theory of gravity in Minkowski space. The basic idea is that the presence of mass affects the worldline of particles in the flat Minkowski background. Although General Relativity is in complete ...
  • Absence of an effective horizon for black holes in gravity's rainbow 
    Ali, Ahmed Farag; Faizal, Mir; Majumder, Barun (arXiv, Cornell University Library, 2014-06)
    We will argue that the divergence in time for the asymptotic observer occurs because of specifying the position of the Horizon beyond the Planck scale. In fact, a similar divergence in time will also occur for an in-going ...
  • 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). ...
  • Accelerated parameter estimation of supermassive black hole binaries in LISA using meshfree approximation 
    Sharma, Abhishek; Sengupta, Anand S.; Mukherjee, Suvodip (Cornell University Library, 2024-09)
    The Laser Interferometer Space Antenna (LISA) will be capable of detecting gravitational waves (GWs) in the milli-Hertz band. Among various sources, LISA will detect the coalescence of supermassive black hole binaries ...
  • Acceleration of solar energetic particles by the shock of interplanetary coronal mass ejection 
    Mondal, Shanwlee Sow; Sarkar, Aveek; Vaidya, Bhargav; Mignone, Andrea (Cornell University Library, 2021-10)
    Interplanetary Coronal Mass Ejection (ICME) shocks are known to accelerate particles and contribute significantly to Solar Energetic Particle (SEP) events. We have performed Magnetohydrodynamic-Particle in Cell (MHD-PIC) ...
  • Accretion properties of MAXI J1813-095 during its failed outburst in 2018 
    Jana, Arghajit; Jaisawal, Gaurava K.; Naik, Sachindra; Kumari, Neeraj; Chatterjee, Debjit; Chatterjee, Kaushik; Bhowmick, Riya; Chakrabarti, Sandip K.; Chang, Hsiang-Kuang; Debnath, Dipak (Cornell University Library, 2021-04)
    We present the results obtained from detailed timing and spectral studies of a black hole candidate MAXI~J1813-095 using (it Swift}, (it NICER), and (it NuSTAR) observations during its 2018 outburst. The timing behaviour ...
  • Acoustic radiation from vortex-barrier interaction in atomic Bose-Einstein condensate 
    Suthar, Kuldeep; Roy, Arko; Angom, D. (Cornell University Library, 2014-05)
    We examine the dynamics of a vortex dipole in the Bose-Einstein condensates (BECs) of trapped dilute atomic gases at zero temperature in the presence of a Gaussian barrier potential. The density-anisotropy induced by the ...
  • 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 ...
  • Advanced Monte Carlo simulation techniques to study polymers under equilibrium conditions 
    Angwani, Monika; Mahendrakar, Tushar; Rane, Kaustubh (Cornell University, 2023-07)
    The advances in materials and biological sciences have necessitated the use of molecular simulations to study polymers. The Markov chain Monte Carlo simulations enable the sampling of relevant microstates of polymeric ...
  • An all-sky search for long-duration gravitational wave transients with initial LIGO 
    Sengupta, Anand (Cornell University Library, 2015-11)
    We present the results of a search for long-duration gravitational wave transients in two sets of data collected by the LIGO Hanford and LIGO Livingston detectors between November 5, 2005 and September 30, 2007, and July ...
  • All-sky search for periodic gravitational waves in the O1 LIGO data 
    Sengupta, Anand (Cornell University Library, 2017-07)
    We report on an all-sky search for periodic gravitational waves in the frequency band 20-475 Hz and with a frequency time derivative in the range of [-1.0, +0.1]e-8 Hz/s. Such a signal could be produced by a nearby spinning ...
