Einstein--Gauss--Bonnet Inflationary Cosmology in Phase- Formalism
Gevorg D. Manucharyan, Igor V. Fomin, Shivam Kumar Mishra +1
A central challenge in testing inflationary scenarios with cosmic microwave background (CMB) data is to derive predictions for cosmological observables that remain accurate beyond…
Structure-Preserving and Pressure-Robust PINNs for Incompressible Oseen Problems
Shiv Mishra, Arbaz Khan
We develop a new class of physics-informed neural network approximations for the stationary Oseen equations based on stability-consistent loss constructions. In contrast to standar…
Propagating Gravitational Waves in Teleparallel Gauss-Bonnet Gravity
Shivam Kumar Mishra, Jackson Levi Said, B. Mishra
Gravitational waves offer a key insight into the viability of classes of gravitational theories beyond general relativity. The observational constraints on their speed of propagati…
Charged particle dynamics in an elliptically polarized electromagnetic wave and a uniform axial magnetic field
Shivam Kumar Mishra, Sarveshwar Sharma, Sudip Sengupta
An analytical study of the charged particle dynamics in the presence of an elliptically polarized electromagnetic wave and a uniform axial magnetic field, is presented. It is found…
