Oscillatory Freeze from Inertial Holographic Dark Energy
Swapnil Kumar Singh
We study a generalized holographic dark energy model in which the infrared cutoff depends on the Hubble parameter and its first two time derivatives. The inclusion of the …

Three-Loop Gauge Beta Functions in Supersymmetric Theories with Exponential Higher Covariant Derivative Regularization
Swapnil kumar Singh
We study the three-loop gauge -functions in general supersymmetric gauge theories regularized by higher covariant derivatives (HCD) supplemented with Pauli--Vill…

Self-Interacting Gravitational Exciton Condensates from Extra-Dimensional Stabilization
Swapnil Kumar Singh
We present a comprehensive study of gravitational exciton dynamics arising from higher-dimensional theories, with a focus on establishing a robust effective framework that incorpor…
