Small Region, Big Impact: Highly Anisotropic Lyman-continuum Escape from a Compact Starburst Region with Extreme Physical Properties

Posted by Chicago

Kavli Affiliate: Michael D. Gladders | First 5 Authors: Keunho J. Kim, Matthew B. Bayliss, Jane R. Rigby, Michael D. Gladders, John Chisholm | Summary: Extreme, young stellar populations are considered the primary contributor to cosmic re-ionization. How Lyman-continuum (LyC) escapes these galaxies remains highly elusive, and it is challenging to observe this process in […]

Acousto-magnonic Hall effect in honeycomb antiferromagnets

Posted by klaurent UCAS

Kavli Affiliate: Mamoru Matsuo | First 5 Authors: Ryotaro Sano, Yuya Ominato, Mamoru Matsuo, , | Summary: The recently discovered van der Waals antiferromagnets have suffered from the lack of a comprehensive method to study their magnetic properties. Here, we propose a dissipationless magnon spin Hall current driven by surface acoustic waves as a novel […]

Continuous Wigner-Mott transition at $ν=1/5$

Posted by Cornell

Kavli Affiliate: Debanjan Chowdhury | First 5 Authors: Thomas G. Kiely, Debanjan Chowdhury, , , | Summary: Electrons can organize themselves into charge-ordered states to minimize the effects of long-ranged Coulomb interactions. In the presence of a lattice, commensurability constraints lead to the emergence of incompressible Wigner-Mott insulators at various rational electron fillings, $nu~=p/q$. The […]

Growth of ultrawide-bandgap BN/diamond heterostructures by pulsed laser deposition

Posted by klaurent Cornell

Kavli Affiliate: Zhiting Tian | First 5 Authors: Abhijit Biswas, Gustavo A. Alvarez, Tao Li, Joyce Christiansen-Salameh, Eugene Jeong | Summary: Heterostructures based on ultrawide-bandgap (UWBG) semiconductors (bandgap >4.0 eV), boron nitride (BN) and diamond are important for next-generation high-power electronics. However, in-situ hetero-epitaxy of BN/diamond or vice-versa remains extremely challenging, due to their non-trivial […]

Transferable screened range-separated hybrid functionals for electronic and optical properties of van der Waals materials

Posted by dbos Berkeley

Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: María Camarasa-Gómez, Ashwin Ramasubramaniam, Jeffrey B. Neaton, Leeor Kronik, | Summary: The accurate description of electronic properties and optical absorption spectra is a long-standing challenge for density functional theory. Recently, the introduction of screened range-separated hybrid (SRSH) functionals for solid-state materials has allowed for the calculation […]
