Kavli Affiliate: Max Tegmark | First 5 Authors: Joshua Engels, David D. Baek, Subhash Kantamneni, Max Tegmark, | Summary: Scalable oversight, the process by which weaker AI systems supervise stronger ones, has been proposed as a key strategy to control future superintelligent systems. However, it is still unclear how scalable oversight itself scales. To address […]

Kavli Affiliate: Debora Sijacki | First 5 Authors: Eun-jin Shin, Debora Sijacki, Matthew C. Smith, Martin A. Bourne, Sophie Koudmani | Summary: While mounting observational evidence suggests that intermediate mass black holes (IMBHs) may be important in shaping the properties of dwarf galaxies both at high redshifts and in the local Universe, our theoretical understanding […]
Kavli Affiliate: Morteza Gharib | First 5 Authors: Scott A. Bollt, Samuel H. Foxman, Morteza Gharib, , | Summary: We present a novel architecture for accelerating PIV calculations. An optical flow hardware accelerator does the brunt of the work, with cross-correlation only providing quick corrections. The result is RapidPIV: a free-to-download software program for real-time […]

Kavli Affiliate: Kerry Vahala | First 5 Authors: Zhiquan Yuan, Jinhao Ge, Peng Liu, Bohan Li, Mingxiao Li | Summary: Achieving compact and efficient visible laser sources is crucial for a wide range of applications. However traditional semiconductor laser technology faces difficulties in producing high-brightness green light, leaving a green gap in wavelength coverage. Second-harmonic […]
Kavli Affiliate: Marcela Carena | First 5 Authors: Marcela Carena, Aurora Ireland, Tong Ou, Isaac R. Wang, | Summary: A precise determination of the bubble wall velocity $v_w$ is crucial for making accurate predictions of the baryon asymmetry and gravitational wave (GW) signals in models of electroweak baryogenesis (EWBG). Working in the local thermal equilibrium […]
Kavli Affiliate: Ulrich Sperhake | First 5 Authors: Gareth Arturo Marks, Seppe J. Staelens, Tamara Evstafyeva, Ulrich Sperhake, | Summary: We study the stability of ultracompact boson stars admitting light rings combining a perturbative analysis with 3+1 numerical-relativity simulations with and without symmetry assumptions. We observe excellent agreement between all perturbative and numerical results which […]
Kavli Affiliate: T. Higuchi | First 5 Authors: K. Ravindran, K. Adamczyk, H. Aihara, S. Bacher, S. Bahinipati | Summary: In 2024, the Belle II experiment resumed data taking after the Long Shutdown 1, which was required to install a two-layer pixel detector and upgrade accelerator components. We describe the challenges of this shutdown and […]
