New dimer integrable systems and defects in five dimensional gauge theory
Norton Lee
We study the relation between the quantum integrable systems derived from the dimer graphs and five dimensional supersymmetric gauge theories on $S^1 \times \mathbb…
Non-minimal Elliptic Threefolds at Infinite Distance II: Asymptotic Physics
Rafael Álvarez-García, Seung-Joo Lee, Timo Weigand
We interpret infinite-distance limits in the complex structure moduli space of F-theory compactifications to six dimensions in the light of general ideas in quantum gravity. The li…
Analytic Formulae for Inflationary Correlators with Dynamical Mass
Shuntaro Aoki, Toshifumi Noumi, Fumiya Sano +1
Massive fields can imprint unique oscillatory features on primordial correlation functions or inflationary correlators, which is dubbed the cosmological collider signal. In this wo…
Non-minimal Elliptic Threefolds at Infinite Distance I: Log Calabi-Yau Resolutions
Rafael Álvarez-García, Seung-Joo Lee, Timo Weigand
We study infinite-distance limits in the complex structure moduli space of elliptic Calabi-Yau threefolds. In F-theory compactifications to six dimensions, such limits include infi…
Cosmological Correlators Through the Looking Glass: Reality, Parity, and Factorisation
David Stefanyszyn, Xi Tong, Yuhang Zhu
We consider the evolution of quantum fields during inflation, and show that the total-energy singularities appearing in the perturbative expansion of the late-time Wavefunction of…
Cancellation of quantum corrections on the soft curvature perturbations
Yuichiro Tada, Takahiro Terada, Junsei Tokuda
We study the cancellation of quantum corrections on the superhorizon curvature perturbations from subhorizon physics beyond the single-clock inflation from the viewpoint of the cos…
