Critical properties of the Majorana chain with competing interactions

Kavli Affiliate: Natalia Chepiga | First 5 Authors: Natalia Chepiga, , , , | Summary: We study critical properties of a Majorana chain in the presence of two competing interactions of the shortest possible range. The obtained phase diagram is very rich and contains nine different phases, including three floating, two Ising, and four gapped […]

Avoiding methane emission rate underestimates when using the divergence method

Kavli Affiliate: Kaisey Mandel | First 5 Authors: Clayton Roberts, Rutger IJzermans, David Randell, Matthew Jones, Philip Jonathan | Summary: Methane is a powerful greenhouse gas, and a primary target for mitigating climate change in the short-term future due to its relatively short atmospheric lifetime and greater ability to trap heat in Earth’s atmosphere compared […]

Dai-Freed anomaly in the standard model and topological inflation

Kavli Affiliate: Masahiro Kawasaki | First 5 Authors: Masahiro Kawasaki, Tsutomu T. Yanagida, , , | Summary: When we impose the discrete symmetry in the standard model we have Dai-Freed global anomalies. However, interestingly if we introduce three right-handed neutrinos we can have an anomaly-free discrete $Z_4$ gauge symmetry. This $Z_4$ symmetry should be spontaneously […]

Subsystem Non-Invertible Symmetry Operators and Defects

Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Weiguang Cao, Linhao Li, Masahito Yamazaki, Yunqin Zheng, | Summary: We explore non-invertible symmetries in two-dimensional lattice models with subsystem $mathbb Z_2$ symmetry. We introduce a subsystem $mathbb Z_2$-gauging procedure, called the subsystem Kramers-Wannier transformation, which generalizes the ordinary Kramers-Wannier transformation. The corresponding duality operators and defects […]

Giant planet engulfment by evolved giant stars: light curves, asteroseismology, and survivability

Kavli Affiliate: Lars Bildsten | First 5 Authors: Christopher E. O’Connor, Lars Bildsten, Matteo Cantiello, Dong Lai, | Summary: About ten percent of Sun-like ($1$-$2 M_odot$) stars will engulf a $1$-$10 M_{rm J}$ planet as they expand during the red giant branch (RGB) or asymptotic giant branch (AGB) phase of their evolution. Once engulfed, these […]

COMAP Early Science: VIII. A Joint Stacking Analysis with eBOSS Quasars

Kavli Affiliate: Sarah E. Church | First 5 Authors: Delaney A. Dunne, Kieran A. Cleary, Patrick C. Breysse, Dongwoo T. Chung, Havard T. Ihle | Summary: We present a new upper limit on the cosmic molecular gas density at $z=2.4-3.4$ obtained using the first year of observations from the CO Mapping Array Project (COMAP). COMAP […]

Universal Gravitational Wave Signatures of Cosmological Solitons

Kavli Affiliate: Misao Sasaki | First 5 Authors: Kaloian D. Lozanov, Misao Sasaki, Volodymyr Takhistov, , | Summary: Cosmological solitonic objects such as monopoles, cosmic strings, domain walls, oscillons and Q-balls often appear in theories of the early Universe. We demonstrate that such scenarios are generically accompanied by a novel production source of gravitational waves […]

Anatomy of parameter-estimation biases in overlapping gravitational-wave signals

Kavli Affiliate: Lijing Shao | First 5 Authors: Ziming Wang, Dicong Liang, Junjie Zhao, Chang Liu, Lijing Shao | Summary: In future gravitational-wave (GW) detections, a large number of overlapping GW signals will appear in the data stream of detectors. When extracting information from one signal, the presence of other signals can cause large parameter […]
