Critical fates induced by interaction competition in the three-dimensional tilted Dirac semimetals

Kavli Affiliate: Jing Wang | First 5 Authors: Jing Wang, Jie-Qiong Li, Wen-Hao Bian, Qiao-Chu Zhang, Xiao-Yue Ren | Summary: The interplay between Coulomb interaction, electron-phonon coupling, and phonon-phonon coupling has a significant impact on the low-energy behavior of three-dimensional type-I tilted Dirac semimetals. To investigate this phenomenon, we construct an effective theory, calculate one-loop […]

Classical radiation fields for scalar, electromagnetic, and gravitational waves with spacetime-symmetry breaking

Kavli Affiliate: Lijing Shao | First 5 Authors: Quentin G. Bailey, Alexander S. Gard, Nils A. Nilsson, Rui Xu, Lijing Shao | Summary: An effective field theory framework is used to investigate some Lorentz-violating effects on the generation of electromagnetic and gravitational waves, complementing previous work on propagation. Specifically we find solutions to a modified, […]

Photochemical origin of SiC$_2$ in the circumstellar envelope of carbon-rich AGB stars revealed by ALMA

Kavli Affiliate: Ke Wang | First 5 Authors: Yanan Feng, Xiaohu Li, Tom J. Millar, Ryszard Szczerba, Ke Wang | Summary: Whether SiC$_2$ is a parent species, that is formed in the photosphere or as a by-product of high-temperature dust formation, or a daughter species, formed in a chemistry driven by the photodestruction of parent […]

Extra-tensor-induced origin for the PTA signal: No primordial black hole production

Kavli Affiliate: Misao Sasaki | First 5 Authors: Mohammad Ali Gorji, Misao Sasaki, Teruaki Suyama, , | Summary: Recently, pulsar timing array (PTA) collaborations announced evidence for an isotropic stochastic gravitational wave (GW) background. The origin of the PTA signal can be astrophysical or cosmological. In the latter case, the so-called secondary scalar-induced GW scenario […]

Freeform three-mirror anastigmatic large-aperture telescope and receiver optics for CMB-S4

Kavli Affiliate: John Carlstrom | First 5 Authors: Patricio A. Gallardo, Roberto Puddu, Kathleen Harrington, Bradford Benson, John Carlstrom | Summary: CMB-S4, the next-generation ground-based cosmic microwave background (CMB) observatory, will provide detailed maps of the CMB at millimeter wavelengths to dramatically advance our understanding of the origin and evolution of the universe. CMB-S4 will […]
