J Phys Condens Matter. 2015 Nov 11;27(44):443002. doi: 10.1088/0953-8984/27/44/443002. Epub 2015 Oct 14.

Recently, several research groups have reported the growth of germanene, a new member of the graphene family. Germanene is in many aspects very similar to graphene, but in contrast to the planar graphene lattice, the germanene honeycomb lattice is...

Radiotherapy vs. Radiosurgery in Treating Patients with Acromegaly: Systematic Review and Meta-Analysis.

Endocrine practice : official journal of the American College of Endocrinology and the American Association of Clinical Endocrinologists

Abu Dabrh A, Asi N, Farah W, Mohammed K, Wang Z, Farah M, Prokop L, Katznelson L, Murad M.
PMID: 25786558
Endocr Pract. 2015 Mar 18;1-33. doi: 10.4158/EP14574.RA. Epub 2015 Mar 18.

OBJECTIVE: When patients with acromegaly have residual disease following surgery, adjuvant radiation therapy is considered. Both stereotactic radiosurgery (SRS) and conventional fractionated radiotherapy (RT) are utilized. We conducted a systematic review and meta-analysis to synthesize the existing evidence to...

Energetics, barriers and vibrational spectra of partially and fully hydrogenated hexagonal boron nitride.

Physical chemistry chemical physics : PCCP

Kroes JM, Fasolino A, Katsnelson MI.
PMID: 27374816
Phys Chem Chem Phys. 2016 Jul 28;18(28):19359-67. doi: 10.1039/c6cp01018k. Epub 2016 Jul 04.

We study hydrogen chemisorption at full coverage and low concentrations on hexagonal boron nitride (h-BN). Chemisorption trends reveal the complex nature of hydrogenation. Barriers for diffusion are found to be significantly altered by the presence of additional H atoms....

Racah materials: role of atomic multiplets in intermediate valence systems.

Scientific reports

Shick AB, Havela L, Lichtenstein AI, Katsnelson MI.
PMID: 26490021
Sci Rep. 2015 Oct 22;5:15429. doi: 10.1038/srep15429.

We address the long-standing mystery of the nonmagnetic insulating state of the intermediate valence compound SmB6. Within a combination of the local density approximation (LDA) and an exact diagonalization (ED) of an effective discrete Anderson impurity model, the intermediate...

PMID: 29099209
Phys Rev Lett. 2017 Oct 20;119(16):167201. doi: 10.1103/PhysRevLett.119.167201. Epub 2017 Oct 19.

We observe and explain theoretically a dramatic evolution of the Dzyaloshinskii-Moriya interaction (DMI) in the series of isostructural weak ferromagnets, MnCO_{3}, FeBO_{3}, CoCO_{3}, and NiCO_{3}. The sign of the interaction is encoded in the phase of the x-ray magnetic...

Chemical modifications and stability of phosphorene with impurities: a first principles study.

Physical chemistry chemical physics : PCCP

Boukhvalov DW, Rudenko AN, Prishchenko DA, Mazurenko VG, Katsnelson MI.
PMID: 25990621
Phys Chem Chem Phys. 2015 Jun 21;17(23):15209-17. doi: 10.1039/c5cp01901j.

We perform a systematic first-principles study of phosphorene in the presence of typical monovalent (hydrogen and fluorine) and divalent (oxygen) impurities. The results of our modeling suggest a decomposition of phosphorene into weakly bonded one-dimensional (1D) chains upon single-...

Effective Hamiltonians for Rapidly Driven Many-Body Lattice Systems: Induced Exchange Interactions and Density-Dependent Hoppings.

Physical review letters

Itin AP, Katsnelson MI.

Phys Rev Lett. 2015 Aug 14;115(7):075301. doi: 10.1103/PhysRevLett.115.075301. Epub 2015 Aug 13.

We consider 1D lattices described by Hubbard or Bose-Hubbard models, in the presence of periodic high-frequency perturbations, such as uniform ac force or modulation of hopping coefficients. Effective Hamiltonians for interacting particles are derived using an averaging method resembling...

Scaling Behavior and Strain Dependence of In-Plane Elastic Properties of Graphene.

Physical review letters

Phys Rev Lett. 2016 Jan 08;116(1):015901. doi: 10.1103/PhysRevLett.116.015901. Epub 2016 Jan 05.

We show by atomistic simulations that, in the thermodynamic limit, the in-plane elastic moduli of graphene at finite temperature vanish with system size L as a power law L(-η(u)) with η(u)≃0.325, in agreement with the membrane theory. We provide...

Magnetism and exchange interaction of small rare-earth clusters; Tb as a representative.

Scientific reports
