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…
Fermion Condensate Inflation, Dynamical Waterfall Mechanism and Primordial Black Holes
Stephon Alexander, Pisin Chen, Jinglong Liu +3
Fermion condensate inflation, where inflation emerges from four-fermion interactions induced by spacetime torsion, removes the need for additional scalar fields beyond the Standard…
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…
