First-principles density functional theory (DFT) study of embedding V and Nb atom in monovacant and divacant graphene is reported. Complete/almost complete spin polarization is ver…
Search for a dark photon at BABAR
David Norvil Brown
We present the results of a search for a dark photon decaying to or in the \babar\ detector. We find no evidence for such a dark photon and set upper limits on th…
Comment on "Stress induction in the bacteria Shewanella oneidensis and Deinococcus radiodurans in response to below-background ionizing radiation", Castillo, et al. Int. J. Rad. Biol., 2015; Early Online DOI:10.3109/09553002.2015.1062571
J. I. Katz
Castillo, et al. report hormesis by background levels of radiation, at which there is ionization per bacterium in a replication time. This suggests radiation products a…
Pressure-induced collapsed-tetragonal phase in SrCo2As2
W. T. Jayasekara, U. S. Kaluarachchi, B. G. Ueland +16
We present high-energy x-ray diffraction data under applied pressures up to p = 29 GPa, neutron diffraction measurements up to p = 1.1 GPa, and electrical resistance measurements u…
Better Band Gaps with Asymptotically Corrected Local Exchange Potentials
Prashant Singh, Manoj K. Harbola, M. Hemanadhan +2
We formulate a spin-polarized van Leeuwen and Baerends (vLB) correction to the local density approximation (LDA) exchange potential [Phys. Rev. A 49, 2421 (1994)] that enforces the…
Gutzwiller Renormalization Group
Nicola Lanatà, Yong-Xin Yao, Xiaoyu Deng +3
We develop a variational scheme called "Gutzwiller renormalization group" (GRG), which enables us to calculate the ground state of Anderson impurity models (AIM) with arbitrary num…
Study of at Belle
V. Bhardwaj
In spite of the fact that the two-body decays into such as are suppressed by the QCD factorization effect, the inclusive branch…
Electronic structure, magnetism and antisite disorder in CoFeCrGe and CoMnCrAl quaternary Heusler alloys
Enamullah, Y. Venkateswara, Sachin Gupta +4
We present a combined theoretical and experimental study of two quaternary Heusler alloys CoFeCrGe (CFCG) and CoMnCrAl (CMCA), promising candidates for spintronics applications. Ma…
Electronic and optical properties of novel carbon allotropes
Zhanyu Wang, R. J. Zhang, Y. X. Zheng +7
The phonon properties, electronic structures and optical properties of novel carbon allotropes, such as monolayer penta-graphene (PG), double-layer PG and T12-carbon, were explored…
A Study of the Energy Dependence of the Underlying Event in Proton-Antiproton Collisions
CDF Collaboration, T. Aaltonen, S. Amerio +401
We study charged particle production in proton-antiproton collisions at 300 GeV, 900 GeV, and 1.96 TeV. We use the direction of the charged particle with the largest transverse mom…

We present a local probe study of the magnetic superconductor, ErNiBC, using magnetic force microscopy at sub-Kelvin temperatures. ErNiBC is an ideal system to expl…
The chiral phase transition for lattice QCD with 2 colour-sextet quarks
J. B. Kogut, D. K. Sinclair
QCD with 2 flavours of massless colour-sextet quarks is studied as a possible walking-Technicolor candidate. We simulate the lattice version of this model at finite temperatures ne…
Magnetically induced phonon splitting in ACrO spinels from first principles
Aleksander L. Wysocki, Turan Birol
We study the magnetically-induced phonon splitting in cubic ACrO (A=Mg, Zn, Cd, Hg) spinels from first principles, and demonstrate that the sign of the splitting, which is…

Valentin Taufour, Srinivasa Thimmaiah, Stephen March +6
The article addresses the possibility of alloy elements in MnBi which may modify the thermodynamic stability of the NiAs-type structure without significantly degrading the magnetic…
Magneto-structural transformations via a solid-state nudged elastic band method: Application to iron under pressure
N. A. Zarkevich, D. D. Johnson
We extend the solid-state nudged elastic band method to handle a non-conserved order parameter - in particular, magnetization, that couples to volume and leads to many observed eff…
