Quantum Matter Makes Lightcones Quantum
Tomohiro Fujita, Misao Sasaki
In gravitational physics, matter does not merely move within spacetime; it also determines the light cones that define causal relations. What happens when the matter that determine…
A Unified Fermionic Origin for Density-Driven Waterfall Inflation and its Multi-Messenger Signatures
Stephon Alexander, Pisin Chen, Jinglong Liu +3
Inflation is conventionally described by fundamental scalar fields whose microscopic origin remains unknown. We propose a different mechanism in which inflation emerges from fermio…
Hybrid Inflation from Fermion Condensate
Stephon Alexander, Pisin Chen, Jinglong Liu +3
We investigate how inflation can emerge from four-fermion interactions generated by spacetime torsion, eliminating the need for additional scalar fields beyond the Standard Model.…
Black Holes Inside and Out 2024: visions for the future of black hole physics
Niayesh Afshordi, Abhay Ashtekar, Enrico Barausse +27
The gravitational physics landscape is evolving rapidly, driven by our ability to study strong-field regions, in particular black holes. Black Holes Inside and Out gathered world e…
Revisiting formation of primordial black holes in a supercooled first-order phase transition
Marcos M. Flores, Alexander Kusenko, Misao Sasaki
We reexamine production of primordial black holes in a supercooled phase transition. While a mere overdensity associated with a surviving false-vacuum patch does not imply formatio…
Yang-Mills instantons as the end point of black hole evaporation
Pisin Chen, Xiao Yan Chew, Misao Sasaki +1
Non-perturbative contributions of the Euclidean path integral are important to understand the information loss paradox. In this paper, we revisit the Yang-Mills instantons in the E…
