Penumbral Inflation from Calabi-Yau Boundaries
Pirzada, Tianjun Li
Mapping Calabi-Yau geometry to early Universe cosmology remains a primary goal in string phenomenology. We present an inflationary mechanism where flux stationarity shifts the fiel…
Shifted Hybrid Realization of Non-Minimal Higgs Inflation in Light of ACT DR6 and Planck Data
Nadir Ijaz, Pirzada, Mansoor Ur Rehman
We investigate non-minimal Higgs inflation in a no-scale-inspired supergravity framework and confront its predictions with the latest CMB constraints from ACT DR6 and \emph{Planck}…
Controlled Penumbral Inflation from Monodromic Valleys
Pirzada, Tianjun Li
Realizing controlled, single-clock inflation in string theory is fundamentally obstructed by the backreaction of heavy moduli. We show that in the \emph{penumbra} -- the near-bound…
Long Inflation Screens Euclidean-Wormhole Initial States
Imtiaz Khan, Pirzada, G. Mustafa +2
Euclidean wormholes can prepare inflation in non--Bunch--Davies initial states, but long Lorentzian expansion screens this memory from the CMB. We derive a visibility bound for Euc…
Dilaton-Flattened Axion Inflation
Pirzada, Ali Muhammad, Tianjun Li +2
We present a solvable same-sector effective theory for anomaly-inspired axion inflation, in which a heavy trace-anomaly mode dynamically backreacts on the axion potential. The tree…
Post-Inflationary Quenched Production of Axion SU(2) Dark Matter
Imtiaz Khan, Pirzada, G. Mustafa
The relic abundance of vector dark matter originating from an inherited axion- condensate is typically determined by implementing an adiabatic matching procedure across the…
