Simple rules govern finite-size effects in scale-free networks
finite-size effects scale-free networks
2011/9/2
We give an intuitive though general explanation of the finitesize effect in scale-free networks in terms of the degree distribution of the starting network. This result clarifies the relevance of the ...
A geometric solution to the coincidence problem, and the size of the landscape as the origin of hierarchy
geometric solution coincidence problem
2010/12/22
Without assuming necessary conditions for observers such as galaxies or entropy production, we show that the causal patch measure predicts the coincidence of vacuum energy and present matter density. ...
Effect of particle size on nonlinear refractive index of Au nanoparticle in PVA solution
Nonlinear properties Z-scan technique nanoparticles
2010/6/30
Nonlinear refractive index of Au nanoparticle suspended in PVA solution was measured using a single beam Z-scan technique. Measurements were carried out using a green CW laser beam operated at 532 nm ...
Simultaneously Finite Size and Interaction Effects on a Harmonically Trapped 87Rb Gas
Bose-Einstein condensation finite size and interaction effects density of states approach
2010/4/9
In the framework of the semiclassical approximation (KB T >> \hbarW), an accurate ansatz formula for the density of states is suggested. This formula is able to include the finite size, interatomic in...
Evolution from Commensurability to Size--Effects Structures in Three--Dimensional Billiards
Size Effects Structures Three--Dimensional Billiards
2010/10/21
We calculated the classical electron dynamics of three–dimensional electrons in a billiard system in tilted magnetic field and analyzed the evolution of trajectories in phase space by means of Poincar...
