Expanding Our Horizons: Rethinking Gravity's Role in the Quantum-to-Classical Transition
Aurora Ireland
The origin of cosmic structure is widely regarded as quantum, yet the Universe today appears classical. Standard lore attributes this to a "quantum-to-classical" transition on supe…
From Fluctuation to Polarization: Imprints of Curvature Perturbations in CMB B-modes from Scalar-Induced Gravitational Waves
Aurora Ireland, Kuver Sinha, Tao Xu
Probing primordial curvature perturbations on small scales, beyond those accessible using cosmic microwave background (CMB) primary anisotropies and Lyman- forest data, remains…
The Discriminant Power of Bubble Wall Velocities: Gravitational Waves and Electroweak Baryogenesis
Marcela Carena, Aurora Ireland, Tong Ou +1
A precise determination of the bubble wall velocity is crucial for making accurate predictions of the baryon asymmetry and gravitational wave (GW) signals in models of electr…
Improved Thermal Resummation for Multi-Field Potentials
Henning Bahl, Marcela Carena, Aurora Ireland +1
The resummation of large thermal corrections to the effective potential is mandatory for the accurate prediction of phase transitions. We discuss the accuracy of different prescrip…
