Contacts With Negative Work of “Adhesion” and Superlubricity [PDF]

, 2020
Van der Waals forces between solids in vacuum are always attractive and are considered as the main source of adhesion. However, in the presence of an intermediate medium, they can also be repelling (Dzyaloshinskii et al., 1961) which means that the “work

Is the Non-Pointness of the Electron Observable in $e^{+}{e}^{-}$ Annihilation at Center-of-Mass Energies 55–207 GeV?

Physics, 2023
The experimental data from VENUS, TOPAS, OPAL, DELPHI, ALEPH and L3 Collaborations collected from 1989 to 2003 are applied to study the quantum electrodynamics (QED) framework through the direct contact interaction term approach, using the annihilation ...

Superstring amplitudes and contact interactions [PDF]

Nuclear Physics B, 1988
Abstract We show that scattering amplitudes computed from light-cone superstring field theory are divergent at tree level. The divergences can be eliminated, and supersymmetry restored, by the addition of certain counter terms to the light-cone hamiltonian.

Local realizations of contact interactions in two- and three-body problems [PDF]

, 1999
Mathematically rigorous theory of the two-body contact interaction in three dimension is reviewed. Local potential realizations of this proper contact interaction are given in terms of Poschl-Teller, exponential and square-well potentials.

Characteristics of the interaction between magnetic-abrasive tool and a processed surface in a circular work zone

Технічна інженерія, 2021
The research discusses the behave of magnetic-abrasive tool (MAT) and the nature of the change of forces mainly of frictional origin which arise in magnetic-abrasive machining (MAM) of cylindric samples with diameter 16 mm, fero-, para- and diamagnetic ...

Subleading contributions to the three-nucleon contact interaction [PDF]

, 2014
We obtain a minimal form of the two-derivative three-nucleon contact Lagrangian, by imposing all constraints deriving from discrete symmetries, Fierz identities and Poincare' covariance.

BCS-BEC crossover of neutron pairs in symmetric and asymmetric nuclear matter [PDF]

, 2007
We propose new types of density dependent contact pairing interaction which reproduce the pairing gaps in symmetric and neutron matter obtained by a microscopic treatment based on the nucleon-nucleon interaction.
