Kavli Affiliate: Li Xin Li |Summary:Spectral lines of heavy atomic elements in the ejecta of supernovae and neutron star mergers can have important contribution to the opacity of the ejecta matter even when the abundance of the elements is very small. Under favorable conditions, the line expansion opacity arising from spectral lines and the expansion […]
Kavli Affiliate: Alessandra Lanzara | Summary:Crystalline symmetries have played a central role in the identification of topological materials. The use of symmetry indicators and band representations have enabled a classification scheme for crystalline topological materials, leading to large scale topological materials discovery. In this work we address whether amorphous topological materials, which lie beyond this […]
Kavli Affiliate: Elise Jennings | Summary:The Reynolds-averaged Navier-Stokes (RANS) equations for steady-state assessment of incompressible turbulent flows remain the workhorse for practical computational fluid dynamics (CFD) applications. Consequently, improvements in speed or accuracy have the potential to affect a diverse range of applications. We introduce a machine learning framework for the surrogate modeling of steady-state […]
Kavli Affiliate: Michael Roukes | Summary:Weak electron-phonon interaction in metals at low temperatures forms the basis of operation for cryogenic hot-electron bolometers and calorimeters. Standard power laws, describing the heat flow in the majority of experiments, have been identified and derived theoretically. However, a full picture encompassing experimentally relevant effects such as reduced dimensionality, material […]
Kavli Affiliate: Herman Marshall | First 5 Authors: Paolo Soffitta, Niccolò Bucciantini, Eugene Churazov, Enrico Costa, Michal Dovciak | Summary: Since the birth of X-ray Astronomy, spectacular advances have been seen in the imaging, spectroscopic and timing studies of the hot and violent X-ray Universe, and further leaps forward are expected in the future. On […]
Kavli Affiliate: Peter W. Graham | First 5 Authors: Kim V. Berghaus, Peter W. Graham, David E. Kaplan, , | Summary: Slow-roll inflation is a successful paradigm. However we find that even a small coupling of the inflaton to other light fields can dramatically alter the dynamics and predictions of inflation. As an example, the […]
Kavli Affiliate: R. G. McMahon | Summary:We present XMM-Newton X-ray observations and analysis of three DES $z>6.5$ quasars (VDES J0020$-$3653 at $z=6.824$, VDES J0244$-$5008 at $z=6.724$ and VDES J0224$-$4711 at $z=6.526$) and six other quasars with $6.438 < z < 6.747$ from the XMM-Newton public archive. Two of the nine quasars are detected at a […]
Kavli Affiliate: R. G. McMahon | First 5 Authors: Estelle Pons, Richard G. McMahon, Manda Banerji, Sophie L. Reed, | Summary: We present XMM-Newton X-ray observations and analysis of three DES $z>6.5$ quasars (VDES J0020$-$3653 at $z=6.824$, VDES J0244$-$5008 at $z=6.724$ and VDES J0224$-$4711 at $z=6.526$) and six other quasars with $6.438 < z < […]
Kavli Affiliate: Todor Milanov | Summary:Fano orbifold lines are classified by the Dynkin diagrams of type $A,D,$ and $E$. It is known that the corresponding total descendant potential is a tau-function of an appropriate Kac–Wakimoto hierarchy. It is also known that in the A-case the Kac–Wakimoto hierarchies admit an extension and that the total descendant […]
