Supersymmetric Dirac-Born-Infeld axionic inflation and non-Gaussianity
Journal of High Energy Physics, 2019 An analysis is given of inflation based on a supersymmetric Dirac-Born-Infeld (DBI) action in an axionic landscape. The DBI model we discuss involves a landscape of chiral superfields with one U(1) shift symmetry which is broken by instanton type non ...

Dimensional reduction and (Anti) de Sitter bounds
Journal of High Energy Physics, 2021 Dimensional reduction has proven to be a surprisingly powerful tool for delineating the boundary between the string landscape and the swampland. Bounds from the Weak Gravity Conjecture and the Repulsive Force Conjecture, for instance, are exactly ...

Eternal inflation and the initial singularity [PDF]
Physical Review Letters, 1994 It is shown that a physically reasonable spacetime that is eternally inflating to the future must possess an initial singularity.

Making the Intangible Tangible: Organizational Capital and Stock Liquidity
British Journal of Management, EarlyView.Abstract We propose an intangibility‐driven stock liquidity hypothesis and explore the role of organizational capital in influencing stock liquidity. Using a sample of 42,682 firm‐year observations, we uncover compelling evidence that firms' intangible organizational capital boosts stock liquidity.

Quantum cosmology, eternal inflation, and swampland conjectures
, 2023 In light of the recent swampland conjectures, we explore quantum cosmology and eternal inflation beyond the slow roll regime. We consider a model of a closed universe with a scalar field $\phi$ in the framework of tunneling approach to quantum cosmology.

The Political Quarterly, Volume 96, Issue 1, Page 180-188, January/March 2025.Abstract The forthcoming general election will be the most consequential electoral contest for the Republic of Ireland in a century. The polity is situated in truly novel territory with the potential for an historic first: the incoming of a Sinn Féin‐led, left‐wing government.

Investigations into the Conditions Necessary for Stochastic Eternal Inflation
, 2012 Theories of cosmological inflation, an early exponential expansion of the universe, have solved the horizon, flatness, and monopole problems in addition to successfully predicting properties of the fluctuations in the cosmic microwave background.

Философия и космологияThe theory of eternal inflation — according to which our observable universe is just one bubble within an endlessly self-replicating multiverse — presents not only a physical but also a hermeneutic challenge.
