A Focused Review of Quintom Cosmology: From Quintom Dark Energy to Quintom Bounce
Tao-tao Qiu, Yifu Cai, Yang Liu +3
The recently released data of DESI DR2 favors a dynamical dark energy theory, with the equation of state crossing the cosmological constant boundary . In this paper, we brief…
The Universal Floquet Modes of (Quasi)-Breathers and Oscillons
Jarah Evslin, Tomasz RomaÅczukiewicz, Katarzyna SlawiÅska +1
Just as linearized perturbations of time-independent configurations can be decomposed into normal modes, those of periodic systems can be decomposed into Floquet modes, which each…
An Extended Soliton's Zero Modes
Jarah Evslin, Hui Liu
Quantum field theory in the presence of localized solitons is more complicated than vacuum sector quantum field theory, largely as a result of the soliton's zero modes. In the pres…
The Domain Wall String's Anti-Stokes Scattering Cross Section
Hengyuan Guo, Jarah Evslin, Hui Liu
We consider anti-Stokes scattering, in which a perturbative meson scatters off of a domain wall string's shape mode excitation, de-exciting it. Previously the probability of this p…
Scheme Dependence of the One-Loop Domain Wall Tension
Jarah Evslin, Hui Liu
The one-loop tension of the domain wall in the 3+1 dimensional double-well model was derived long ago using dimensional regularization. The methods used can only be applied…
Testing the Gallium anomaly using Electron-Neutrino Scattering
Emilio Ciuffoli, Jarah Evslin, Ruixuan Gao +2
The Gallium anomaly is an unexplained deficit in the neutrinos observed during the calibration of GALLEX and SAGE using a Cr radioactive source and recently confirmed by BES…
