We show that for $5/6$-th of all primes $p$, Hilbert's 10-th Problem is unsolvable for $\mathbb{Q}(\zeta_3, \sqrt[3]{p})$. We also show that there is an infinite set $S$ of square free integers such tha Hilbert's 10-th Problem is unsolvable over the

A visibility-based angular bispectrum estimator for radio-interferometric data

Autor: Gill, Sukhdeep Singh, Bharadwaj, Somnath, Ali, Sk. Saiyad, Elahi, Khandakar Md Asif

Considering radio-interferometric observations, we present a fast and efficient estimator to compute the binned angular bispectrum (ABS) from gridded visibility data. The estimator makes use of Fast Fourier Transform (FFT) techniques to compute the b

Transistors based on Novel 2-D Monolayer Semiconductors Bi2O2Se, InSe, and MoSi2N4 for Enhanced Logic Density Scaling

Autor: Nandan, Keshari, Naseer, Ateeb, Agarwal, Amit, Bhowmick, Somnath, Chauhan, Yogesh S.

Publikováno v: IEEE Transactions on Electron Devices, 2024

Making ultra-short gate-length transistors significantly contributes to scaling the contacted gate pitch. This, in turn, plays a vital role in achieving smaller standard logic cells for enhanced logic density scaling. As we push the boundaries of min

Scaling Up Purcell-Enhanced Self-Assembled Nanoplasmonic Perovskite Scintillators into the Bulk Regime

Autor: Makowski, Michal, Ye, Wenzheng, Kowal, Dominik, Maddalena, Francesco, Mahato, Somnath, Amrillah, Yudhistira Tirtayasri, Zajac, Weronika, Witkowski, Marcin Eugeniusz, Drozdowski, Konrad Jacek, Nathaniel, Dang, Cuong, Cybinska, Joanna, Drozdowski, Winicjusz, Nugroho, Ferry Anggoro Ardy, Dujardin, Christophe, Wong, Liang Jie, Birowosuto, Muhammad Danang

Scintillators, which convert high-energy radiation into detectable photons, play a crucial role in medical imaging and security applications. The enhancement of scintillator performance through nanophotonics and nanoplasmonics, specifically using the

Dynamically Encircled Higher-order Exceptional Points in an Optical Fiber

Autor: Roy, Arpan, Laha, Arnab, Biswas, Abhijit, Miranowicz, Adam, Pal, Bishnu P., Ghosh, Somnath

The unique properties of exceptional point (EP) singularities, arising from non-Hermitian physics, have unlocked new possibilities for manipulating light-matter interactions. A tailored gain-loss variation, while encircling higher-order EPs dynamical
