Kavli Affiliate: Jia Liu | First 5 Authors: Jinhui Guo, Jinhui Guo, , , | Summary: We propose and study a purely inelastic scalar dark matter model, where two real scalars-dark matter $phi_1$ and its excited partner $phi_2$ interact with the Standard Model via a Higgs portal. After mass diagonalization, only inelastic couplings remain, allowing […]
Kavli Affiliate: Pau Amaro Seoane | First 5 Authors: Pau Amaro Seoane, Pau Amaro Seoane, , , | Summary: The existence of curvature singularities and the information and firewall paradoxes are significant problems for the conventional black hole model. The black mirror hypothesis provides a CPT-symmetric alternative to the classical description of black hole, offering […]
Kavli Affiliate: Robert L. Byer | First 5 Authors: Jakob M. Grzesik, Jakob M. Grzesik, , , | Summary: Scattering experiments with energetic particles, such as free electrons, have been historically used to reveal the quantum structure of matter. However, realizing coherent interactions between free-electron beams and solid-state quantum systems has remained out of reach, […]

Kavli Affiliate: Xiang Zhang | First 5 Authors: Jiaqi Wei, Jiaqi Wei, , , | Summary: Artificial intelligence (AI) is reshaping scientific discovery, evolving from specialized computational tools into autonomous research partners. We position Agentic Science as a pivotal stage within the broader AI for Science paradigm, where AI systems progress from partial assistance to […]
Kavli Affiliate: Xiang Zhang | First 5 Authors: Yukang Lin, Yukang Lin, , , | Summary: Creative image in advertising is the heart and soul of e-commerce platform. An eye-catching creative image can enhance the shopping experience for users, boosting income for advertisers and advertising revenue for platforms. With the advent of AIGC technology, advertisers […]
Kavli Affiliate: Lijing Shao | First 5 Authors: Peixiang Ji, Peixiang Ji, , , | Summary: Compact stars in scalar-tensor gravity have been extensively investigated, but relatively few studies have focused on highly relativistic neutron stars (NSs) with an extremely dense core region where the trace of the energy-momentum tensor reverses its sign. In this […]
Kavli Affiliate: Lars Bildsten | First 5 Authors: Tin Long Sunny Wong, Tin Long Sunny Wong, , , | Summary: Following a type Ia supernova (SN Ia) in a double white dwarf (WD) binary, a surviving WD companion leaves at its orbital velocity $approx 1$,000 – 3,000 km/s. The Gaia mission has discovered seven such […]
Kavli Affiliate: Lars Bildsten | First 5 Authors: Jared A. Goldberg, Jared A. Goldberg, , , | Summary: We present the first 3D Radiation-Hydrodynamics simulations of partially-stripped ($M_mathrmcoresim10M_odot$, $M_mathrmenvsim0.1-1M_odot$) Yellow Supergiant ($Lsim10^5$, $T_mathrmeffapprox5000-8000$K) envelopes, constructed with Athena++. These envelope models represent the progenitors of Type IIb supernovae (SNe-IIb), which have lost a substantial fraction of […]
