CMB lensing with shear-only reconstruction on the full sky

Posted by klaurent Cambridge

Kavli Affiliate: Anthony Challinor | First 5 Authors: Frank J. Qu, Anthony Challinor, Blake D. Sherwin, , | Summary: Reconstruction of gravitational lensing effects in the CMB from current and upcoming surveys is still dominated by temperature anisotropies. Extragalactic foregrounds in temperature maps can induce significant biases in the lensing power spectrum obtained with the […]

The EDGE-CALIFA survey: The role of spiral arms and bars in driving central molecular gas concentrations

Posted by klaurent Peking

Kavli Affiliate: Luis C. Ho | First 5 Authors: Si-Yue Yu, Veselina Kalinova, Dario Colombo, Alberto D. Bolatto, Tony Wong | Summary: Shocks and torques produced by non-axisymmetric structures such as spiral arms and bars may transport gas to galaxy central regions. We test this hypothesis by studying the dependence of concentration of CO luminosity […]

Numerical modeling of the multi-stage Stern$unicode{x2013}$Gerlach experiment by Frisch and Segrè using co-quantum dynamics via the Schrödinger equation

Posted by klaurent Caltech

Kavli Affiliate: Lihong V. Wang | First 5 Authors: Zhe He, Kelvin Titimbo, David C. Garrett, S. Suleyman Kahraman, Lihong V. Wang | Summary: We use a new theory termed co-quantum dynamics (CQD) to numerically model spin flip in the multi-stage Stern$unicode{x2013}$Gerlach (SG) experiment conducted by R. Frisch and E. Segr`e. This experiment consists of […]

Breaking down the magnonic Wiedemann-Franz law in the hydrodynamic regime

Posted by klaurent UCAS

Kavli Affiliate: Mamoru Matsuo | First 5 Authors: Ryotaro Sano, Mamoru Matsuo, , , | Summary: Recent experiments have shown an indication of a hydrodynamic magnon behavior in ultrapure ferromagnetic insulators; however, its direct observation is still lacking. Here, we derive a set of coupled hydrodynamic equations and study the thermal and spin conductivities for […]
