The fine-tuning problems of particle physics and anthropic mechanisms
Particle physics the multiverse fine-tuning the multiverse
2014/12/20
Many of the classic problems of particle physics appear in a very different light when viewed from the perspective of the multiverse. Most importantly the two great ``fine tuning'' problems that motiv...
Tuning magnetism in FeAs-based materials via tetrahedral structure
Tuning magnetism FeAs-based materials tetrahedral structure
2012/2/27
Resistivity, magnetic susceptibility, neutron scattering and x-ray crystallography measurements were used to study the evolution of magnetic order and crystallographic structure in single-crystal samp...
A One-Dimensional Local Tuning Algorithm for Solving GO Problems with Partially Defined Constraints
Global optimization multiextremal constraints geometric algorithms index scheme local tuning
2011/8/18
Abstract: Lipschitz one-dimensional constrained global optimization (GO) problems where both the objective function and constraints can be multiextremal and non-differentiable are considered in this p...
Strain-tuning of quantum dot optical transitions via laser-induced surface defects
Strain-tuning quantum dot optical transitions laser-induced surface defects
2011/8/17
Abstract: We discuss the fine-tuning of the optical properties of self-assembled quantum dots by the strain perturbation introduced by laser-induced surface defects. We show experimentally that the qu...
Selective tuning of high-Q silicon photonic crystal nanocavities via laser-assisted local oxidation
Local oxidation cavity resonance tuning Thermal oxidation
2011/8/29
We examine the cavity resonance tuning of high-Q silicon photonic crystal heterostructures by localized laser-assisted thermal oxidation using a 532 nm continuous wave laser focused to a 2.5 m radius...
The fine-tuning problem revisited in the light of the Taylor-Lagrange renormalization scheme
The fine-tuning problem the Taylor-Lagrange renormalization scheme
2010/12/23
We re-analyse the perturbative radiative corrections to the Higgs mass within the Standard Model in the light of the Taylor-Lagrange renormalization scheme. This scheme naturally leads to completely ...
Fine tuning epitaxial strain in ferroelectrics: PbxSr(1-x)TiO3 on DyScO3
ferroelectrics strain thin films phase diagram phase boundaries
2010/11/24
Epitaxial strain can be efficiently used to modify the properties of ferroelectric thin films. From the experi-mental viewpoint, the challenge is to fine-tune the magnitude of the strain. We illustrat...
Tuning the spin texture in binary and ternary surface alloys on Ag(111)
Tuning the spin texture ternary surface alloys
2010/11/19
Recently, a giant spin splitting has been observed in surface alloys on noble metal (111) surfaces as a result of a strong structural modification at the surface as well as the large atomic spin-orbit...
Enhancing the superconducting transition temperature of BaSi2 by structural tuning
superconducting transition temperature of BaSi2
2010/11/18
We present a joint experimental and theoretical study of the superconducting phase of the lay-
ered binary silicide BaSi2. Compared with the layered AlB2 structure of graphite or diboride-like superc...
Tuning electron spin lattices by the nonparaxial Talbot effect
electron spin nonparaxial Talbot effect
2010/11/17
We propose a spin polarized Talbot effect for an electron beam scattered from a grating of magnetic nanostructures. Existing periodic magnetic nanostructures can be used in conjunction with electron-b...
Tuning macro-twinned domain sizes and the b-variants content of the adaptive 14-modulated martensite in epitaxial Ni-Mn-Ga films by co-sputtering
Magnetic shape memory alloys epitaxial films adaptive modulated-martensites twinning
2010/11/19
order to obtain modulated-martensite in our epitaxial Ni-Mn-Ga films, we have tuned the composition by using a co-sputtering process. Here we present how the composition affects the variant distributi...
We demonstrate broadband tuning of an optomechanical microcavity optical resonance by exploring the large optomechanical coupling of a double-wheel microcavity and its uniquely low mechanical stiffne...
General-purpose Monte Carlo event generators have become important tools in particle physics, allowing the simulation of exclusive hadronic final states.In this article we examine the Pythia 8 generat...
