A procedure for calculating the many-particle Bohm quantum potential
L. Delle Site
In a recent work, M.Kohout (M.Kohout, Int.J.Quant.Chem. 87, 12 2002) raised the important question of how to make a correct use of Bohm's approach for defining a quantum potential.…
Thomas-Fermi generalized approach for studying systems under pressure
E. Cappelluti, L. Delle Site
In a previous work one of the authors proposed a simple model for studying systems under pressure based on the Thomas-Fermi (TF) model of single atom. In this work we intend to ext…
Magneto-controlled nonlinear optical materials
J. P. Huang, K. W. Yu
We exploit theoretically a magneto-controlled nonlinear optical material which contains ferromagnetic nanoparticles with a non-magnetic metallic nonlinear shell in a host fluid. Su…
Nonlinear alternating current responses of electrorheological solids
J. P. Huang
When a composite containing nonlinear dielectric particles suspended in a host medium is subjected to a sinusoidal alternating current (ac) electric field, the dielectric response…
Directed Polymers with Constrained Winding Angle
Franco Ferrari, Vakhtang G. Rostiashvili, Thomas A. Vilgis
In this article we study from a non-perturbative point of view the entanglement of two directed polymers subjected to repulsive interactions given by a Dirac function potential…
Localization of a multiblock copolymer at a selective interface: Scaling predictions and Monte Carlo verification
Andrea Corsi, Andrey Milchev, Vakhtang G. Rostiashvili +1
We investigate the localization of a hydrophobic - polar (HP) - regular copolymer at a selective solvent-solvent interface with emphasis on the impact of block length on the co…
Optical response of strongly coupled metal nanoparticles in dimer arrays
J. J. Xiao, J. P. Huang, K. W. Yu
The optical responses of structured array of noble-metal nanoparticle dimers immersed in a glass matrix are investigated theoretically, motivated by the recent experimental observa…
Scaling the alpha-relaxation time of supercooled fragile organic liquids
C. Dreyfus, A. Le Grand, J. Gapinski +2
It was shown recently that the structural alpha-relaxation time tau of supercooled o-terphenyl depends on a single control parameter Gamma, which is the product of a function of de…
Strain-dependent localization, microscopic deformations, and macroscopic normal tensions in model polymer networks
Carsten Svaneborg, Gary S. Grest, Ralf Everaers
We use molecular dynamics simulations to investigate the microscopic and macroscopic response of model polymer networks to uniaxial elongations. By studying networks with strands l…
Twirling DNA Rings - Swimming Nanomotors Ready for a Kickstart
Igor M. Kulic, Rochish Thaokar, Helmut Schiessel
We propose a rotary DNA nanomachine that shows a continuous rotation with a frequency of 10^2 -10^4 Hz. This motor consists of a DNA ring whose elastic features are tuned such that…
Sliding grafted polymer layers
Vladimir A. Baulin, Albert Johner, Carlos M. Marques
We study theoretically the structure of sliding grafted polymer layers or SGP layers. These interfacial structures are built by attaching each polymer to the substrate with a ring-…
Constrained dynamics of a polymer ring enclosing a constant area
Arti Dua, Thomas A. Vilgis
The dynamics of a polymer ring enclosing a constant {\sl algebraic} area is studied. The constraint of a constant area is found to couple the dynamics of the two Cartesian componen…
Geometry of surface mediated interactions
Martin Michael Mueller, Markus Deserno, Jemal Guven
Soft interfaces can mediate interactions between particles bound to them. The force transmitted through the surface geometry on a particle may be expressed as a closed line integra…
Magnetization of polydisperse colloidal ferrofluids: Effect of magnetostriction
J. P. Huang, C. Holm
We exploit magnetostriction in polydisperse ferrofluids in order to generate nonlinear responses, and apply a thermodynamical method to derive the desired nonlinear magnetic suscep…
Optical nonlinearity enhancement of graded metal-dielectric composite films
J. P. Huang, L. Dong, K. W. Yu
We have derived the local electric field inside graded metal-dielectric composite films with weak nonlinearity analytically, which further yields the effective linear dielectric co…
Nonlinear ac responses of electro-magnetorheological fluids
J. P. Huang, K. W. Yu
We apply a Langevin model to investigate the nonlinear ac responses of electro-magnetorheological (ERMR) fluids under the application of two crossed dc magnetic (z axis) and electr…
Statistical-mechanical theory of the overall magnetic properties of mesocrystals
J. P. Huang
The mesocrystal showing both electrorheological and magnetorheological effects is called electro-magnetorheological (EMR) solids. Prediction of the overall magnetic properties of t…
Theory of electrical conductivities of ferrogels
J. P. Huang
Conductive organic polymers can be formulated with polymers that incorporate fine dispersed metallic particles. In this work, we present a general model for ferrogels which are che…
New nonlinear dielectric materials: Linear electrorheological fluids under the influence of electrostriction
J. P. Huang
The usual approach to the development of new nonlinear dielectric materials focuses on the search for materials in which the components possess an inherently large nonlinear dielec…
Theory of Nucleosome Corkscrew Sliding in the Presence of Synthetic DNA Ligands
Farshid Mohammad-Rafiee, Igor M. Kulic, H. Schiessel
Histone octamers show a heat-induced mobility along DNA. Recent theoretical studies have established two mechanisms that are qualitatively and quantitatively compatible with in vit…
Nucleosome interactions in chromatin: fiber stiffening and hairpin formation
Boris Mergell, Ralf Everaers, Helmut Schiessel
We use Monte Carlo simulations to study attractive and excluded volume interactions between nucleosome core particles in 30 nm-chromatin fibers. The nucleosomes are treated as disk…
Capillary bridging and long-range attractive forces in a mean-field approach
D. Andrienko, P. Patricio, O. I. Vinogradova
When a mixture is confined, one of the phases can condense out. This condensate, which is otherwise metastable in the bulk, is stabilized by the presence of surfaces. In a sphere-p…
