The density determination of a small solid object with a mass of only a few hundred milligrams is always a difficult and often an ellusive measurement. The advent of highly accurate hydrostatic weighing techniques and the density scale based on solid objects are utilized in a two liquid float method presented here that incorporates the advantages of this technology. The resulting measurement is...

We show theoretically that the second layer of He adsorbed on graphite and solidified at 4/7 of the first-layer density is close to the fluid-solid boundary with substantial density fluctuations on the third layer. The solid shows a translational symmetry breaking as in charge-ordered insulators of electronic systems. We construct a minimal model beyond the multiple-exchange Heisenberg model. A...

This paper investigates the performance of the errorforecasting decoding for an interleaved block code on Gilbert–Elliott channels in terms of the word-error probability, which is the sum of the decoder error and failure probabilities. We derive expressions by constructing several Markov chains, starting from a two-state Markov chain of the Gilbert–Elliott channel model. The derived formulas ar...

We have developed a technique to tune the carrier density in graphene using a lithium-ion-based solid electrolyte. We demonstrate that the solid electrolyte can be used as both a substrate to support graphene and a back gate. It can induce a change in the carrier density as large as 1 × 1014 cm-2, which is much larger than that induced with oxide-film dielectrics, and it is comparable with that...

Modeling of x-ray spectra emitted from a solid-density strongly coupled plasma formed in short-duration, high-power laser–matter interactions represents a highly challenging task due to extreme conditions found in these experiments. In this paper we present recent progress in the modeling and analysis of Kα emission from solid-density laser-produced titanium plasmas. The selfconsistent modeling...

Stable fluid and solid particle phases are essential to the simulation of continuum fluids and solids using smooth particle applied mechanics. We show that density-dependent potentials, such as Phi rho=1/2 Sigma(rho-rho 0)2, along with their corresponding constitutive relations, provide a simple means for characterizing fluids and that special stabilization potentials, with density gradients or...

We have considered the properties of anisotropic two-leg ladder models with S = 1/2 or S = 1 spins on the rungs, using White’s density matrix renormalization group method. We have generalized the method by taking into account the symmetries of the model in order to reduce the dimensions of the matrix to be diagonalized, thereby making possible to consider more states. The boundaries in the para...

With the application of a homogenization theory, based on Fourier formalism (which provides efficient and exact formulas by which to determine all components effective stiffness mass density tensors, valid in regime large wavelengths), new approach calculate quasi-static response three-dimensional solid-solid phononic crystals is reported. The derived this work for calculating elastic parameter...
