Non-Markovian Memory-Induced Effects in Quantum Cosmology
Aarav Shah, Paulo Moniz, Oem Trivedi +1
We study memory effects in quantum cosmology by extending the semiclassical Wheeler-DeWitt framework beyond its usual local form. The main idea is to introduce a causal memory kern…
Inflation and Primordial Perturbations in Fractal Cosmology
Aarav Shah, Paulo Moniz, Maxim Khlopov +2
We study inflationary dynamics within the framework of fractal cosmology, where space is characterized by an effective non-integer dimension . In our work, fractal effects are s…
Particle production and Higgs reheating
Aarav Shah, Kanabar Jay, Maxim Khlopov +2
Reheating is essential for transforming the cold, vacuum dominated Universe at the end of inflation into the hot thermal bath required by the Standard Model. In many well motivated…
Cosmology in the De Donder-Weyl Formulation of Einstein-Cartan Gravity
Aarav Shah, M. Yu. Khlopov, M. Krasnov
We investigate torsion-driven cosmological dynamics within the framework of Einstein-Cartan gravity using the De Donder-Weyl Hamiltonian formalism, where the tetrad and Lorentz con…
The Ultra Slow-Roll Phase Of Warm Inflation In Braneworld Cosmology
Aarav Shah
Slow-roll of the inflaton (inflationary field) defines the standard dynamics of the inflationary epoch. However, the inflaton deviates from slow-roll when it encounters an extremel…
PALADIN: Self-Correcting Language Model Agents to Cure Tool-Failure Cases
Sri Vatsa Vuddanti, Aarav Shah, Satwik Kumar Chittiprolu +4
Tool-augmented language agents frequently fail in real-world deployment due to tool malfunctions--timeouts, API exceptions, or inconsistent outputs--triggering cascading reasoning…
