A volume of fluid method for simulating fluid/fluid interfaces in contact with solid boundaries

, 2015
In this paper, we present a novel approach to model the fluid/solid interaction forces in a direct solver of the Navier-Stokes equations based on the volume of fluid interface tracking method.

Models for quantitative charge imaging by atomic force microscopy [PDF]

, 2001
Two models are presented for quantitative charge imaging with an atomic-force microscope. The first is appropriate for noncontact mode and the second for intermittent contact (tapping) mode imaging.

Interaction and excitonic insulating transition in graphene

, 2009
The strong long-range Coulomb interaction between massless Dirac fermions in graphene can drive a semimetal-insulator transition. We show that this transition is strongly suppressed when the Coulomb interaction is screened by such effects as disorder ...

The Influence of Technological Factors of Centrifugal Planetary Treating the Roughness of the Internal Channels of Small-Sized Parts

Инженерные технологии и системы
Introduction. Treating small-sized parts having internal channels is a complex technological task that can be solved using dispersed grinding materials. The required surface quality of the internal channels can be achieved by using centrifugal planetary ...

Chiral Symmetry and N*(1440) -> N pi pi Decay

, 2004
The N*(1440) -> N pi pi decay is studied by making use of the chiral reduction formula. This formula suggests a scalar-isoscalar pion-baryon contact interaction which is absent in the recent study of Hern{\'a}ndez et al.

Exact Eigenstates for Contact Interactions

Journal of Statistical Physics, 2002
We show that in d>1 dimensions the N-particle kinetic energy operator with periodic boundary conditions has symmetric eigenfunctions which vanish at particle encounters, and give a full description of these functions. In two and three dimensions they represent common eigenstates of bosonic Hamiltonians with any kind of contact interactions, and ...

Evaluation of the Adaptive Behavior of a Shell-Type Elastic Element of a Drilling Shock Absorber with Increasing External Load Amplitude

Vibration
Vibration loads during deep drilling are one of the main causes of reduced service life of drilling tools and emergency failure of downhole motors. This work investigates the adaptive operation of an original elastic element based on an open cylindrical ...

Emergent Fermi sea in a system of interacting bosons

, 2015
An understanding of the possible ways in which interactions can produce fundamentally new emergent many-body states is a central problem of condensed matter physics.
