The magnetic structure of the $zigzag$ chain family Na$_{x}$Ca$_{1-x}$V$_2$O$_4$ determined by muon-spin rotation

, 2010
We present muon-spin rotation measurements on polycrystalline samples of the complete family of the antiferromagnetic (AF) $zigzag$ chain compounds, Na$_x$Ca$_{1-x}$V$_2$O$_4$. In this family, we explore the magnetic properties from the metallic NaV$_2$O$

Investigating the Switching Dynamics of Antiferroelectric Capacitor Using Multidomain Phase-Field Approach

IEEE Journal of the Electron Devices Society
Here, we present a compact model based on multidomain phase-field approach that can capture the hysteresis loop and the transient negative capacitance (NC) regions in Metal-Antiferroelectric-Metal structures.

Boundary induced phase transition with stochastic entrance and exit

, 2014
We study an open-chain totally asymmetric exclusion process (TASEP) with stochastic gates present at the two boundaries. The gating dynamics has been modeled keeping the physical system of ion-channel gating in mind.

Synergistic effects of Al and Mo on coarsening kinetics of Ni-based superalloys at 1200°C

Materials Research Letters
The interaction effects of γ-strengthening and γ'-former elements have long troubled the alloying design of superalloys, especially improving γ'-thermostability by Al addition against higher temperatures.

Time-periodic phases in populations of nonlinearly coupled oscillators with bimodal frequency distributions

, 1997
The mean field Kuramoto model describing the synchronization of a population of phase oscillators with a bimodal frequency distribution is analyzed (by the method of multiple scales) near regions in its phase diagram corresponding to synchronization to ...

Construction of equilibrium networks with an energy function

, 2007
We construct equilibrium networks by introducing an energy function depending on the degree of each node as well as the product of neighboring degrees.

Comparative analysis of different numerical schemes in solute trapping simulations by using the phase-field model with finite interface dissipation [PDF]

Journal of Mining and Metallurgy. Section B: Metallurgy, 2016
Two different numerical schemes, the standard explicit scheme and the time-elimination relaxation one, in the framework of phase-field model with finite interface dissipation were employed to investigate the solute trapping effect in a Si-4.5 at.

Emergence of foams from the breakdown of the phase field crystal model

, 2010
The phase field crystal (PFC) model captures the elastic and topological properties of crystals with a single scalar field at small undercooling. At large undercooling, new foam-like behavior emerges.
