Modeling Dense Star Clusters in the Milky Way and Beyond with the Cluster Monte Carlo Code

Kavli Affiliate: Pau Amaro Seoane | First 5 Authors: Carl L. Rodriguez, Newlin C. Weatherford, Scott C. Coughlin, Pau Amaro Seoane, Katelyn Breivik | Summary: We describe the public release of the Cluster Monte Carlo Code (CMC) a parallel, star-by-star $N$-body code for modeling dense star clusters. CMC treats collisional stellar dynamics using H’enon’s method, […]

A long-lived solid-state optical quantum memory for high-rate quantum repeaters

Kavli Affiliate: Wolfgang Tittel | First 5 Authors: Mohsen Falamarzi Askarani, Antariksha Das, Jacob H. Davidson, Gustavo C. Amaral, Neil Sinclair | Summary: We argue that long optical storage times are required to establish entanglement at high rates over large distances using memory-based quantum repeaters. Triggered by this conclusion, we investigate the $^3$H$_6$ $leftrightarrow$ $^3$H$_4$ […]

Efficient Fizeau Drag from Dirac electrons in monolayer graphene

Kavli Affiliate: Alex Zettl | First 5 Authors: Wenyu Zhao, Sihan Zhao, Hongyuan Li, Sheng Wang, Shaoxin Wang | Summary: Fizeau demonstrated in 1850 that the speed of light can be modified when it is propagating in moving media. Can we achieve such control of the light speed efficiently with a fast-moving electron media by […]

Enhanced spin-orbit coupling and orbital moment in ferromagnets by electron correlations

Kavli Affiliate: Bo Gu | First 5 Authors: Ze Liu, Jing-Yang You, Bo Gu, Sadamichi Maekawa, Gang Su | Summary: In atomic physics, the Hund rule says that the largest spin and orbital state is realized due to the interplay of the spin-orbit coupling (SOC) and the Coulomb interactions. Here, we show that in ferromagnetic […]
