Lorentzian Vacuum Transitions: Open or Closed Universes?
Sebastian Cespedes, Senarath P. de Alwis, Francesco Muia +1
We consider the generalisation of quantum tunneling transitions in the WKB approximation to the time-independent functional Schrödinger and Wheeler-DeWitt equations. Following a Lo…
Cosmological Trans-Planckian Conjectures are not Effective
C. P. Burgess, S. P. de Alwis, F. Quevedo
It is remarkable that the primordial fluctuations as revealed by the CMB coincide with what quantum fluctuations would look like if they were stretched across the sky by accelerate…
Challenges and Opportunities of Gravitational Wave Searches at MHz to GHz Frequencies
N. Aggarwal, O. D. Aguiar, A. Bauswein +22
The first direct measurement of gravitational waves by the LIGO and Virgo collaborations has opened up new avenues to explore our Universe. This white paper outlines the challenges…
On de Sitter String Vacua from Anti-D3-Branes in the Large Volume Scenario
Chiara Crinò, Fernando Quevedo, Roberto Valandro
We consider de Sitter vacua realised in concrete type IIB Calabi-Yau compactifications with an anti D3-brane at the tip of a warped throat of Klebanov-Strassler type. The Kähler mo…
UV Shadows in EFTs: Accidental Symmetries, Robustness and No-Scale Supergravity
C. P. Burgess, Michele Cicoli, David Ciupke +2
We argue that accidental approximate scaling symmetries are robust predictions of weakly coupled string vacua, and show that their interplay with supersymmetry and other (generalis…
A Systematic Approach to Kähler Moduli Stabilisation
Shehu AbdusSalam, Steven Abel, Michele Cicoli +2
Achieving full moduli stabilisation in type IIB string compactifications for generic Calabi-Yau threefolds with hundreds of Kähler moduli is notoriously hard. This is due not just…
Joseph Polchinski: A Biographical Memoir
Raphael Bousso, Fernando Quevedo, Steven Weinberg
Joseph Polchinski (1954-2018), one of the the leading theoretical physicists of the past 50 years, was an exceptionally broad and deep thinker. He made fundamental contributions to…
