Kavli Affiliate: Max Tegmark | First 5 Authors: David “davidad” Dalrymple, Joar Skalse, Yoshua Bengio, Stuart Russell, Max Tegmark | Summary: Ensuring that AI systems reliably and robustly avoid harmful or dangerous behaviours is a crucial challenge, especially for AI systems with a high degree of autonomy and general intelligence, or systems used in safety-critical […]
Kavli Affiliate: Eric D. Miller | First 5 Authors: Arnab Sarkar, Catherine E. Grant, Eric D. Miller, Mark Bautz, Benjamin Schneider | Summary: Galactic cosmic ray (GCR) particles have a significant impact on the particle-induced background of X-ray observatories, and their flux exhibits substantial temporal variability, potentially influencing background levels. In this study, we present […]

Kavli Affiliate: Frank Wilczek | First 5 Authors: Frank Wilczek, Zara Yu, , , | Summary: Postulating the identification of $psi^*(x, t) psi(x,t)$ with a physical probability density is unsatisfactory conceptually and overly limited practically. For electrons, there is a simple, calculable relativistic correction proportional to $nabla psi^* cdot nabla psi$. In particular, zeroes of […]

Kavli Affiliate: Frank Wilczek | First 5 Authors: Frank Wilczek, , , , | Summary: If we consider a cat to be an isolated mechanical system governed by T-invariant mechanics, then its ability to land on its feet after being released from rest is incomprehensible. It is more appropriate to treat the cat as a […]
Kavli Affiliate: Max Tegmark | First 5 Authors: Subhash Kantamneni, Ziming Liu, Max Tegmark, , | Summary: Integrable partial differential equation (PDE) systems are of great interest in natural science, but are exceedingly rare and difficult to discover. To solve this, we introduce OptPDE, a first-of-its-kind machine learning approach that Optimizes PDEs’ coefficients to maximize […]
Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Mary Anne Limbach, Jacob Lustig-Yaeger, Andrew Vanderburg, Johanna M. Vos, Rene Heller | Summary: The highest priority recommendation of the Astro2020 Decadal Survey for space-based astronomy was the construction of an observatory capable of characterizing habitable worlds. In this paper series we explore the detectability of and […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Vinh Tran, Daniel Gilman, Mark Vogelsberger, Xuejian Shen, Stephanie O’Neil | Summary: We investigate a self-interacting dark matter (SIDM) model featuring a velocity-dependent cross section with an order-of-magnitude resonant enhancement of the cross section at $sim 16,{rm km},{rm s}^{-1}$. To understand the implications for the structure of […]
