{sc HIFlow}: Generating Diverse HI Maps and Inferring Cosmology while Marginalizing over Astrophysics using Normalizing Flows

Posted by klaurent Tokyo

Kavli Affiliate: David N. Spergel | First 5 Authors: Sultan Hassan, Francisco Villaescusa-Navarro, Benjamin Wandelt, David N. Spergel, Daniel Anglés-Alcázar | Summary: A wealth of cosmological and astrophysical information is expected from many ongoing and upcoming large-scale surveys. It is crucial to prepare for these surveys now and develop tools that can efficiently extract most […]

Relative Entropy Gradient Sampler for Unnormalized Distributions

Posted by klaurent Peking

Kavli Affiliate: Feng Yuan | First 5 Authors: Xingdong Feng, Yuan Gao, Jian Huang, Yuling Jiao, Xu Liu | Summary: We propose a relative entropy gradient sampler (REGS) for sampling from unnormalized distributions. REGS is a particle method that seeks a sequence of simple nonlinear transforms iteratively pushing the initial samples from a reference distribution […]

Oxide two-dimensional electron gas with high mobility at room-temperature

Posted by klaurent Cornell

Kavli Affiliate: Darrell G. Schlom | First 5 Authors: Kitae Eom, Hanjong Paik, Jinsol Seo, Neil Campbell, Evgeny Y. Tsymbal | Summary: The prospect of 2-dimensional electron gases (2DEGs) possessing high mobility at room temperature in wide-bandgap perovskite stannates is enticing for oxide electronics, particularly to realize transparent and high-electron mobility transistors. Nonetheless only a […]

Separation of Artifacts from Spin-Torque Ferromagnetic Resonance Measurements of Spin-Orbit Torque for the Low-Symmetry van der Waals Semi-Metal ZrTe$_textbf{3}$

Posted by klaurent Cornell

Kavli Affiliate: Daniel C. Ralph | First 5 Authors: Thow Min Cham, Saba Karimeddiny, Vishakha Gupta, Joseph A. Mittelstaedt, Daniel C. Ralph | Summary: We measure spin-orbit torque generated by exfoliated layers of the low-symmetry semi-metal ZrTe$_3$ using the spin-torque ferromagnetic resonance (ST-FMR) technique. When the ZrTe$_3$ has a thickness greater than about 10 nm, […]
