Snowmass2021 Cosmic Frontier: Synergies between dark matter searches and multiwavelength/multimessenger astrophysics

Posted by klaurent MIT

Kavli Affiliate: Lina Necib | First 5 Authors: Shin’ichiro Ando, Sebastian Baum, Michael Boylan-Kolchin, Esra Bulbul, Michael Burgess | Summary: This whitepaper focuses on the astrophysical systematics which are encountered in dark matter searches. Oftentimes in indirect and also in direct dark matter searches, astrophysical systematics are a major limiting factor to sensitivity to dark […]

Theoretical developments in the SMEFT at dimension-8 and beyond

Posted by klaurent Tokyo

Kavli Affiliate: Tom Melia, Hitoshi Murayama | First 5 Authors: Simone Alioli, Radja Boughezal, Weiguang Cao, Gauthier Durieux, Lukáš Gráf | Summary: In this contribution to the Snowmass 2021 process we review theoretical developments in the Standard Model Effective Field Theory (SMEFT) with a focus on effects at the dimension-8 level and beyond. We review […]

Accurate non-empirical range-separated hybrid van der Waals density functional for complex molecular problems, solids, and surfaces

Posted by klaurent Berkeley

Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Vivekanand Shukla, Yang Jiao, Jung-Hoon Lee, Elsebeth Schroder, Jeffrey B. Neaton | Summary: We introduce a new, general-purpose, range-separated hybrid van der Waals density ph{functional, termed vdW-DF-ahbr,} within the non-empirical vdW-DF method [JPCM 32, 393001 (2020)]. It combines correlation from vdW-DF2 with a screened Fock exchange […]

A second-generation range-separated hybrid van der Waals density functional

Posted by klaurent Berkeley

Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Vivekanand Shukla, Yang Jiao, Jung-Hoon Lee, Elsebeth Schroder, Jeffrey B. Neaton | Summary: We define, test, and illustrate use of a range-separated (screened) hybrid, termed vdW-DF2-ahbr and abbreviated AHBR, that uses the second-generation nonlocal-correlation formulation [PRB {bf 82}, 081101(R) (2010)] within the van der Waals density […]
