Mechanism of Hollow Nanoparticle Formation Due to Shape Fluctuations
Hollow Nanoparticle Formation Shape Fluctuations
2015/10/16
Shape fluctuations in nanoparticles strongly influence their stability. Here, we introduce a quantitative model of such shape fluctuations and apply this model to the important case of Pt-shell/transi...
Hierarchical Consensus Formation Reduces the Influence of Opinion Bias
Hierarchical Consensus Formation Influence of Opinion Bias Physics and Society
2012/4/19
We study the role of hierarchical structures in a simple model of collective consensus formation based on the bounded confidence model with continuous individual opinions. For the particular variation...
Scalar models for the generalized Chaplygin gas and the structure formation constraints
Scalar models the generalized Chaplygin gas
2010/12/24
The generalized Chaplygin gas model represents a tentative to unify dark matter and dark energy. It is characterized by a fluid with an equation of state $p = - A/\rho^\alpha$. It can be obtained fro...
Signatures of Wigner molecule formation in interacting Dirac fermion quantum dots
Signatures of Wigner molecule formation Dirac fermion quantum dots
2010/11/18
We study N interacting massless Dirac fermions confined in a two-dimensional quantum dot.
Physical realizations of this problem include a graphene monolayer and the surface state of a strong topologi...

Scalar models generalized Chaplygin gas structure formation constraints
2010/12/21
The generalized Chaplygin gas model represents a tentative to unify dark matter and dark
energy. It is characterized by a fluid with an equation of state p = −A/ .
Stochastic Structural Stability Theory applied to roll/streak formation in boundary layer shear flow
Stochastic Structural Stability Theory boundary layer shear flow
2010/11/16
Stochastic Structural Stability Theory (SSST) provides an autonomous, deterministic, nonlinear dynamical system for evolving the statistical mean state of a turbulent system. In this work SSST is appl...
Quantum fluctuations can promote or inhibit glass formation
Quantum fluctuations can glass formation
2010/11/17
The very nature of glass is somewhat mysterious: while relaxation times in glasses are of
sufficient magnitude that large-scale motion on the atomic level is essentially as slow as it is in the cryst...
We propose an experiment to study collective behavior in a nonlinear medium of trapped ions. Using laser cooling and heating and an anharmonic trap potential, one can turn an ion into a nonlinear van...
Hamiltonian motions of plane curves and formation of singularities and bubbles
Hamiltonian motions plane curves
2010/4/1
A class of Hamiltonian deformations of plane curves is defined and studied. Hamiltonian deformations of conics and cubics are considered as illustrative examples. These deformations are described by s...
Formation of Random Dark Envelope Solitons from Incoherent Waves
Random Dark Envelope Solitons Incoherent Waves
2010/4/7
This letter reports experimental results on a new type of soliton: the random temporal dark soliton. One excites an incoherent large-amplitude propagating spin-wave packet in a ferromagnetic film stri...
Characterization Of Oil Shale Residue And Rejects From Irati Formation By Electron Paramagnetic Resonance
Oil shale EPR Quartz
2010/7/5
In this study, sedimentary organic matter of oil shale rejects, calschist, shale fine and the so called retorted shale from Irati formation was characterized. EPR was used to analyse the samples regar...
Multi-channel modelling of the formation of vibrationally cold polar KRb molecules
Multi-channel modelling vibrationally cold polar KRb molecules
2010/4/8
We describe the theoretical advances that influenced the experimental creation of vibrationally and translationally cold polar $^{40}$K$^{87}$Rb molecules \cite{nphys08,science08}. Cold molecules were...
