Kavli Affiliate: John Reynolds | Authors: Courtney Glavis-Bloom, Casey R Vanderlip and John H Reynolds | Summary: Aging is the greatest risk factor for the development of neurodegenerative diseases, yet we still do not understand how the aging process leads to pathological vulnerability. The research community has relied heavily on mouse models, but the considerable […]
Kavli Affiliate: Robert Hawkins | Authors: Sreejan Kumar, Theodore R. Sumers, Takateru Yamakoshi, Ariel Goldstein, Uri Hasson, Kenneth A. Norman, Thomas L. Griffiths, Robert D. Hawkins and Samuel A. Nastase | Summary: Piecing together the meaning of a narrative requires understanding not only the individual words but also the intricate relationships between them. How does […]
Kavli Affiliate: Lars Bildsten | First 5 Authors: Jared A. Goldberg, Yan-fei Jiang, Lars Bildsten, , | Summary: Using Athena++, we perform 3D Radiation-Hydrodynamic calculations of the radiative breakout of the shock wave in the outer envelope of a red supergiant (RSG) which has suffered core collapse and will become a Type IIP supernova. The […]
Kavli Affiliate: Michael Fausnaugh | First 5 Authors: Jason T. Hinkle, Christopher S. Kochanek, Benjamin J. Shappee, Patrick J. Vallely, Katie Auchettl | Summary: We analyze high-cadence data from the Transiting Exoplanet Survey Satellite (TESS) of the ambiguous nuclear transient (ANT) ASASSN-18el. The optical changing-look phenomenon in ASASSN-18el has been argued to be due to […]

Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Dan Hooper, Aurora Ireland, Gordan Krnjaic, , | Summary: The origin of our universe’s cosmological magnetic fields remains a mystery. In this study, we consider whether these magnetic fields could have been generated in the early universe by a population of charged, spinning primordial black holes. To […]
Kavli Affiliate: David T. Limmer | First 5 Authors: Michelle C. Anderson, Addison J. Schile, David T. Limmer, , | Summary: We present a means of studying rare reactive pathways in open quantum systems using Transition Path Theory and ensembles of quantum jump trajectories. This approach allows for elucidation of reactive paths for dissipative, nonadiabatic […]
Kavli Affiliate: Feng Wang | First 5 Authors: Ya-Jing Ma, Feng Wang, Xian-Yuan Wu, Kai-Yuan Cai, | Summary: This paper focuses on the extreme-value problem for Shannon entropy of the joint distribution with given marginals. It is proved that the minimum-entropy coupling must be of order-preserving, while the maximum-entropy coupling coincides with the independent one. […]
Kavli Affiliate: Misao Sasaki | First 5 Authors: Sugumi Kanno, Misao Sasaki, , , | Summary: We compute the leading order non-Gaussianity, i.e., the bispectrum, of the tensor perturbation in the general $alpha$-vacuum on de Sitter space in general relativity. In addition to the well-known Bunch-Davies (BD) vacuum, there exits an infinite number of de […]
Kavli Affiliate: Ke Wang | First 5 Authors: He Liu, Ting Zhang, Ke Wang, Fei Gao, Gang Xu | Summary: Hole spins confined in semiconductor quantum dot systems have gained considerable interest for their strong spin-orbit interactions (SOIs) and relatively weak hyperfine interactions. Here we experimentally demonstrate a tunable SOI in a double quantum dot […]
