The phase diagram and critical behavior of the three-state majority-vote model
(Institute of Physics, 2010)
The three-state majority-vote model with noise on Erdos-Renyi random graphs has been studied. Using Monte Carlo simulations we obtain the phase diagram, along with the critical exponents. Exact results for limiting cases ...
A unified picture of the covalent bond within quantum-accurate force fields: From organic molecules to metallic complexes? reactivity
(American Association for the Advancement of Science (AAAS), 2019)
Computational studies of chemical processes taking place over extended size and time scales are inaccessible by electronic structure theories and can be tackled only by atomistic models such as force fields. These have ...
Perpendicular exchange bias effect in sputter-deposited CoFe/IrMn bilayers
(2014)
CoFe/IrMn bilayers with perpendicular magneti
zation for various IrMn layer thicknesses exhibit
unusual two-step hysteresis loops with both posi
tive and negative loop shifts. Observed at room
temperature in the as-grown ...
Charge transfer energies of benzene physisorbed on a graphene sheet from constrained density functional theory
(2016)
Constrained density functional theory (CDFT) is used to evaluate the energy level alignment of a benzene
molecule as it approaches a graphene sheet. Within CDFT the problem is conveniently mapped onto evaluating
total ...
Quasi-two-dimensional exciton in ZnSe/ZnMgSSe single quantum well
(American Physical Society, 1995)
We have studied the quasi-two-dimensional exciton in ZnSe/ZnxMg1 ? xSySe1 ? y (x=0.85, y=0.21) single quantum wells (SQWs) by photoluminescence and photoluminescence excitation spectroscopy. Self-consistent calculations ...
Experimental analysis of polarization dependence of ultrafast gain dynamics in SOAs
(2005)
Nonlinear polarization rotation in semiconductor optical amplifiers has been the focus of a lot of work in the past decade. A lot of research has been devoted to this phenomenon due to its possible use in all-optical ...
Observations of Low Frequency Solar Radio Bursts from the Rosse Solar-Terrestrial Observatory
(2012)
The Rosse Solar-Terrestrial Observatory (RSTO; www.rosseobservatory.ie) was established at Birr Castle, Co. Offaly, Ireland (53?05'38.9'', 7?55'12.7'') in 2010 to study solar radio bursts and the response of the Earth?s ...
Narrow-band tunable terahertz emission from ferrimagnetic Mn<inf>3-x</inf>Ga thin films
(2016)
Narrow-band terahertz emission from coherently excited spin precession in metallic ferrimagnetic Mn3-xGa Heusler alloy nanofilms has been observed. The efficiency of the emission, per nanometer film thickness, is comparable ...
Nickel sulfide - an itinerant electron antiferromagnet.
(American Physical Society, 1974)
Antiferromagnetic nickel sulphide has a small temperature-independent magnetic susceptibility. The ordered moment per nickel atom, measured with neutrons, decreases from 1.45?B to 1.00?B at 4.2 K with a decrease of 0.6% ...
d° magnetism in oxides and alkaline-earth hexaborides
