Novel Conservative Methods for Adaptive Force Softening in Collisionless and Multi-Species N-Body Simulations

Posted by Peking

Philip F. Hopkins, Ethan O. Nadler, Michael Y. Grudic, Xuejian Shen, Isabel Sands | Summary: [[{“value”:”Modeling self-gravity of collisionless fluids (e.g. ensembles of dark matter, stars, black holes, dust, planetary bodies) in simulations is challenging and requires some force softening. It is often desirable to allow softenings to evolve adaptively, in any high-dynamic range simulation, […]

Architectures for Multinode Superconducting Quantum Computers

Posted by Caltech

Kavli Affiliate: Andrei Faraon | First 5 Authors: James Ang, Gabriella Carini, Yanzhu Chen, Isaac Chuang, Michael Austin DeMarco | Summary: Many proposals to scale quantum technology rely on modular or distributed designs where individual quantum processors, called nodes, are linked together to form one large multinode quantum computer (MNQC). One scalable method to construct […]

A Measurement of the CMB Temperature Power Spectrum and Constraints on Cosmology from the SPT-3G 2018 TT/TE/EE Data Set

Posted by Stanford

Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: L. Balkenhol, D. Dutcher, A. Spurio Mancini, A. Doussot, K. Benabed | Summary: We present a sample-variance-limited measurement of the temperature power spectrum ($TT$) of the cosmic microwave background (CMB) using observations of a $sim! 1500 ,mathrm{deg}^2$ field made by SPT-3G in 2018. We report multifrequency power […]

A hybrid quantum photonic interface for $^{171}$Yb solid-state qubits

Posted by Caltech

Kavli Affiliate: Andrei Faraon | First 5 Authors: Chun-Ju Wu, Daniel Riedel, Andrei Ruskuc, Ding Zhong, Hyounghan Kwon | Summary: $^{171}$Yb$^{3+}$ in YVO$_4$ is a promising candidate for building quantum networks with good optical addressability, excellent spin properties and a secondary nuclear-spin quantum register. However, the associated long optical lifetime necessitates coupling to optical resonators […]
