Radial and Non-Radial Oscillations of Inverted Hybrid Stars

Kavli Affiliate: Lijing Shao | First 5 Authors: Chen Zhang, Yudong Luo, Hong-bo Li, Lijing Shao, Renxin Xu | Summary: We study the radial and non-radial oscillations of Cross stars (CrSs), i.e., stars with a quark matter crust and a hadronic matter core in an inverted order compared to conventional hybrid stars. We draw comparisons […]

A Mini-Neptune Orbiting the Metal-poor K Dwarf BD+29 2654

Kavli Affiliate: Christopher J. Burke | First 5 Authors: Fei Dai, Kevin C. Schlaufman, Henrique Reggiani, Luke Bouma, Andrew W. Howard | Summary: We report the discovery and Doppler mass measurement of a 7.4-day 2.3-$R_oplus$ mini-Neptune around a metal-poor K dwarf BD+29 2654 (TOI-2018). Based on a high-resolution Keck/HIRES spectrum, the Gaia parallax, and multi-wavelength […]

Emergent conformal boundaries from finite-entanglement scaling in matrix product states

Kavli Affiliate: Long Zhang | First 5 Authors: Rui-Zhen Huang, Long Zhang, Andreas M. Läuchli, Jutho Haegeman, Frank Verstraete | Summary: The use of finite entanglement scaling with matrix product states (MPS) has become a crucial tool for studying 1+1d critical lattice theories, especially those with emergent conformal symmetry. We argue that finite entanglement introduces […]

Dark matter search with a strongly-coupled hybrid spin system

Kavli Affiliate: Jia Liu | First 5 Authors: Kai Wei, Zitong Xu, Yuxuan He, Xiaolin Ma, Xing Heng | Summary: Observational evidence suggests the existence of dark matter (DM), which comprises approximately $84.4%$ of matter in the universe. Recent advances in tabletop quantum sensor technology have enabled searches for nongravitational interactions of DM. Our experiment […]

Dark Matter Search with a Resonantly-Coupled Hybrid Spin System

Kavli Affiliate: Jia Liu | First 5 Authors: Kai Wei, Zitong Xu, Yuxuan He, Xiaolin Ma, Xing Heng | Summary: Recent advances in tabletop quantum sensor technology have enabled searches for nongravitational interactions of dark matter (DM). Traditional axion DM experiments rely on sharp resonance, resulting in extensive scanning time to cover a wide mass […]

Turbulence Supported Massive Star Envelopes

Kavli Affiliate: Lars Bildsten | First 5 Authors: William Schultz, Lars Bildsten, Yan-Fei Jiang, , | Summary: The outer envelopes of massive ($Mgtrsim10,M_{odot}$) stars exhibit large increases in opacities from forests of lines and ionization transitions (particularly from iron and helium) that trigger near-surface convection zones. One-dimensional models predict density inversions and supersonic motions that […]
