Pervasive beyond room-temperature ferromagnetism in a doped van der Waals magnet: Ni doped Fe$_5$GeTe$_2$ with $T_{text{C}}$ up to 478 K

Posted by klaurent February 28, 2022Cornell

Kavli Affiliate: David A. Muller | First 5 Authors: Xiang Chen, Yu-Tsun Shao, Rui Chen, Sandhya Susarla, Tom Hogan | Summary: The existence of long range magnetic order in low dimensional magnetic systems, such as the quasi-two-dimensional (2D) van der Waals (vdW) magnets, has attracted intensive studies of new physical phenomena. The vdW Fe$_N$GeTe$_2$ ($N$ […]

Tunable superconducting coupling of quantum dots via Andreev bound states in semiconductor-superconductor nanowires

Posted by klaurent February 28, 2022Delft

Kavli Affiliate: Michael Wimmer | First 5 Authors: Chun-Xiao Liu, Guanzhong Wang, Tom Dvir, Michael Wimmer, | Summary: Semiconductor quantum dots have proven to be a useful platform for quantum simulation in the solid state. However, implementing a superconducting coupling between quantum dots mediated by a Cooper pair has so far suffered from limited tunability […]

FIRE-3: Updated Stellar Evolution Models, Yields, & Microphysics and Fitting Functions for Applications in Galaxy Simulations

Posted by klaurent February 28, 2022March 21, 2022MIT

Kavli Affiliate: Lina Necib | First 5 Authors: Philip F. Hopkins, Andrew Wetzel, Coral Wheeler, Robyn Sanderson, Michael Y. Grudic | Summary: Increasingly, uncertainties in predictions from galaxy formation simulations (at sub-Milky Way masses) are dominated by uncertainties in stellar evolution inputs. In this paper, we present the full set of updates from the FIRE-2 […]

Predicting the Thermal Sunyaev-Zel’dovich Field using Modular and Equivariant Set-Based Neural Networks

Posted by klaurent February 28, 2022Tokyo

Kavli Affiliate: David N. Spergel | First 5 Authors: Leander Thiele, Miles Cranmer, William Coulton, Shirley Ho, David N. Spergel | Summary: Theoretical uncertainty limits our ability to extract cosmological information from baryonic fields such as the thermal Sunyaev-Zel’dovich (tSZ) effect. Being sourced by the electron pressure field, the tSZ effect depends on baryonic physics […]
