Introduction
I am pursuing a PhD degree and research at the University of Greifswald, Germany in the area of multi-messenger astronomy and compact stars. I obtained an Integrated Master's in Physics and a bachelor's in Computer Science from BITS Pilani K.K. Birla Goa campus. I am interested in high energy astrophysical phenomena and the numerical tools we can use to understand them.

Article
Full-text available
Universal quantum computation can be realised using both continuous-time and discrete-time quantum walks. We present a version based on single particle discrete-time quantum walk to realize multi-qubit computation tasks. The scalability of the scheme is demonstrated by using a set of walk operations on a closed lattice form to implement the univers...
Article
Caustics are singularities that occur naturally in optical, hydrodynamic, and quantum waves, giving rise to high-amplitude patterns that can be described using catastrophe theory. In this paper we study caustics in a statistical field theory setting in the form of the sine-Gordon model that describes a variety of physical systems including coupled...

Article
Full-text available
The core collapse of rapidly rotating massive ∼ 10 M ⊙ stars (“collapsars”), and the resulting formation of hyperaccreting black holes, comprise a leading model for the central engines of long-duration gamma-ray bursts (GRBs) and promising sources of r -process nucleosynthesis. Here, we explore the signatures of collapsars from progenitors with hel...

Technical Report
In this “Study Oriented Project” (SOP), Mixmaster Universe is studied briefly for examining the debated chaotic nature of the Mixmaster metric towards cosmic singularity. As a precursor to this, Hamiltonian formalism of general relativity has been studied in Numerical Relativity framework. Simulation of Mixmaster Universe in Misner Chitre like vari...
