Kavli Affiliate: Anna Frebel | First 5 Authors: Guilherme Limberg, Silvia Rossi, Timothy C. Beers, Hélio D. Perottoni, Angeles Pérez-Villegas | Summary: We analyze the dynamical properties of $sim$1500 very metal-poor (VMP; [Fe/H] $lesssim -2.0$) halo stars, based primarily on medium-resolution spectroscopic data from the HK and Hamburg/ESO surveys. These data, collected over the past […]
Kavli Affiliate: Michael Wimmer | First 5 Authors: Kim Pöyhönen, Daniel Varjas, Michael Wimmer, Anton R. Akhmerov, | Summary: Platforms for creating Majorana quasiparticles rely on superconductivity and breaking of time-reversal symmetry. By studying continuous deformations to known trivial states, we find that the relationship between superconducting pairing and time reversal breaking imposes rigorous bounds […]
Kavli Affiliate: Yasunori Nomura | First 5 Authors: Yasunori Nomura, , , , | Summary: We portray the structure of quantum gravity emerging from recent progress in understanding the quantum mechanics of an evaporating black hole. Quantum gravity admits two different descriptions, based on Euclidean gravitational path integral and a unitarily evolving holographic quantum system, […]
