Observation of a new boson at a mass of 125 GeV with the CMS experiment at the LHC

S. Chatrchyan, +2863 more
- 17 Sep 2012 - 
TL;DR: In this paper, results from searches for the standard model Higgs boson in proton-proton collisions at 7 and 8 TeV in the CMS experiment at the LHC, using data samples corresponding to integrated luminosities of up to 5.8 standard deviations.
Journal ArticleDOI

Quasiparticle energies and band gaps in graphene nanoribbons.

TL;DR: In this article, the quasiparticle energies and band gaps of graphene nanoribbons were calculated using a first-principles many-electron Green's function approach within the GW approximation.

Quasiparticle Energies and Band Gaps of Graphene Nanoribbons

TL;DR: The quasiparticle band gaps found here suggest that use of GNRs for electronic device components in ambient conditions may be viable, and compared with previous tight-binding and density functional theory studies, show significant self-energy corrections.
Journal ArticleDOI

Ising-Type Magnetic Ordering in Atomically Thin FePS3.

TL;DR: It is demonstrated that FePS3 exhibits an Ising-type antiferromagnetic ordering down to the monolayer limit, in good agreement with the Onsager solution for two-dimensional order-disorder transition.
