Efficient Reconstruction of Matched-Filter Signal-to-Noise Ratio Time Series from Nearby Templates for Compact Binary Coalescences Searches
Yasuhiro Murakami, Tathagata Ghosh, Soichiro Morisaki
We present a method for efficiently searching long-duration gravitational wave signals from compact binary coalescences (CBCs). The approach exploits the smooth frequency-domain be…
From Symmetry Breaking to Majoron Cosmology: Insights from NANOGrav 15-year Data
Tathagata Ghosh, Kousik Loho, Sudip Manna
We study the cosmology of a modified majoron model motivated by the need to protect a global symmetry from gravity-induced hard explicit breaking (by operators) a…
Fractional anisotropic Calderón problem with external data
Ali Feizmohammadi, Tuhin Ghosh, Katya Krupchyk +3
In this paper, we solve the fractional anisotropic Calderón problem with external data in the Euclidean space, in dimensions two and higher, for smooth Riemannian metrics that agr…
Lower bound of the expressibility of ansatzes for Variational Quantum Algorithms
Tamojit Ghosh, Arijit Mandal, Shreya Banerjee +2
The expressibility of an ansatz used in a variational quantum algorithm is defined as the uniformity with which it can explore the space of unitary matrices, i.e., its covering num…
