TL;DR: This work provides density functional theory-based structural models for the Ruddlesden-Popper (RP) phases of AVA2(CH3NH3) n-1Pb nI3 n+1 for n = 1, 2, and 3 and validate with experimental data on polycrystalline samples.

TL;DR: Fumagalli et al. as discussed by the authors investigated the dielectric, structural, and dynamical properties of confined water placed between two parallel graphene walls at different interdistances from the angstrom scale to a few tens of nanometer.

TL;DR: In this paper, the dielectric, structural and dynamical properties of confined water placed between two parallel graphene walls at different inter distances from the Angstrom scale to few tens of nanometer have been investigated using molecular dynamics.

TL;DR: In this paper , the authors evaluate the orbital magnetization and optical conductivity as physical observables for a massive Dirac fermion insulator irradiated by light carrying nonzero orbital angular momentum (OAM).

TL;DR: In this article , the presence of flat bands in the energy spectrum of a hexagon of graphene was investigated and it was shown that a fully hydrogenated hexagon with six hydrogen atoms sitting on top and bottom in consecutive order exhibits Dirac cones in the electronic band structure with a $20%$ smaller Fermi velocity as compared to the pristine graphene.
