  • 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 ...
  • Ghosh, Avirup; Jana, Soumya; Mishra, Akash K.; Sarkar, Sudipta (Cornell University Library, 2019-06)
    General relativity may be an effective theory with higher curvature correction terms in the action. Inclusion of these terms leads to exciting new possibilities, e.g., gravitational and electromagnetic perturbations following ...
  • Bhattacharyya, Arpan; Das, Saurya; Haque, S. Shajidul; Underwood, Bret (Cornell University Library, 2020-01)
    We compute the quantum circuit complexity of the evolution of scalar curvature perturbations on expanding backgrounds, using the language of squeezed vacuum states. In particular, we construct a simple cosmological model ...
