Comment on ‘Discussion on novel attractive force between ions in quantum plasmas—failure of simulations based on a density functional approach’ [PDF]

open access: yes, 2013
In a recent paper (Shukla et al 2013 Phys. Scr. 87 018202) the authors criticized our analysis of the screened proton potential in dense hydrogen that was based on ab initio density functional theory (DFT) simulations (Bonitz et al 2013 Phys. Rev.

Symmetry breaking and electrostatic attraction between two identical surfaces [PDF]

open access: yes, 2008
By allowing the surface charge of one surface to affect the adsorption equilibrium of the other, we establish the existence of a long-range attractive interaction between two identical surfaces in an electrolyte containing polyvalent counterions with a ...

Repulsive black holes and higher-derivatives

open access: yesJournal of High Energy Physics, 2022
In two-derivative theories of gravity coupled to matter, charged black holes are self-attractive at large distances, with the force vanishing at zero temperature.

Optical field and attractive force at the subwavelength slit.

open access: yesOptics Express, 2016
In recent works, a novel light-induced attractive force was predicted between two metal plates. This force arises by the interaction of surface plasmons which are excited at the metal when a transverse magnetic mode propagates through a subwavelength ...

Thinning of superfluid films below the critical point

open access: yes, 2007
Experiments on $^4$He films reveal an attractive Casimir-like force at the bulk $\lambda$-point, and in the superfluid regime. Previous work has explained the magnitude of this force at the $\lambda$ transition and deep in the superfluid region but not ...

Long-distance behavior of $q\bar{q}$ color dependent potentials at finite temperature

open access: yes, 2004
SU(3) heavy quark potentials at finite temperature are studied with quenched lattice QCD using the stochastic gauge-fixing method. In addition to the standard color average channel, we investigate $q\bar{q}$ potentials in singlet and octet channels. % We

A Short Review of Electromagnetic Attractive Forming and Its Applications

open access: yesMetals
Electromagnetic attractive forming (EMAF), as an emerging branch of electromagnetic forming (EMF), has attracted increasing attention due to its unique capacity to shape workpieces toward the coil, offering distinct advantages in forming small-diameter ...

An attractive nucleon-nucleon spin-orbit force from skyrmions with dilatons

open access: yes, 1995
Within the skyrmion approach for the nucleon-nucleon force, difficulties have been experienced in obtaining an isoscalar attractive spin-orbit potential, in parallel to the problems of finding attraction in the isoscalar central potential.

Social force model for pedestrian dynamics. [PDF]

open access: yesPhysical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 1995
It is suggested that the motion of pedestrians can be described as if they would be subject to ``social forces.'' These ``forces'' are not directly exerted by the pedestrians' personal environment, but they are a measure for the internal motivations of ...
