Kavli Affiliate: Craig Hogan | First 5 Authors: Craig Hogan, Ohkyung Kwon, Stephan S. Meyer, Nathaniel Selub, Frederick Wehlen | Summary: Anisotropy of space-time is measured on the scale of the cosmic horizon, using the angular correlation function $C(Theta)$ of cosmic microwave background (CMB) temperature at large angular separation $Theta$. Even-parity correlation $C_{rm even}(Theta)$ is […]

Kavli Affiliate: Craig Hogan | First 5 Authors: Craig Hogan, Ohkyung Kwon, Stephan S. Meyer, Nathaniel Selub, Frederick Wehlen | Summary: We test the hypothesis that angular correlations of gravitationally-induced temperature anisotropy in the cosmic microwave background (CMB) vanish over a range of large angular separations constrained by causality. Standard conformal geometry is used to […]

Kavli Affiliate: Craig Hogan | First 5 Authors: Craig Hogan, Ohkyung Kwon, Stephan S. Meyer, Nathaniel Selub, Frederick Wehlen | Summary: We formulate a new hypothesis for causal coherence of gravitational quantum fluctuations, and test its predicted constraints on large-scale angular correlations in the cosmic microwave background (CMB). We posit that {it quantum fluctuations generate […]
Kavli Affiliate: Craig Hogan | First 5 Authors: Craig Hogan, Ohkyung Kwon, Stephan S. Meyer, Nathaniel Selub, Frederick Wehlen | Summary: Causal relationships in conformal geometry are used to analyze angular boundaries of cosmic microwave background (CMB) correlations. It is shown that curvature correlations limited to timelike intervals on world lines that have connected causal […]
Kavli Affiliate: Menno Veldhorst | First 5 Authors: Xin Zhang, Elizaveta Morozova, Maximilian Rimbach-Russ, Daniel Jirovec, Tzu-Kan Hsiao | Summary: The coherent control of interacting spins in semiconductor quantum dots is of strong interest for quantum information processing as well as for studying quantum magnetism from the bottom up. Here, we present a $2times4$ germanium […]
