We present a complete analytical solution to the quantum problem of particle in Yukawa potential, using supersymmetry and systematic expansion corresponding super-potentials. Results for critical screening ground state improve several figures existing results based on both numerical solutions approximation methods. Our calculation order (a0/D)2 squared wavefunction at origin, which enter darkon...

We consider a chirally invariant lattice Higgs-Yukawa model based on the Neuberger overlap operator D(ov). As a first step towards the eventual determination of Higgs mass bounds we study the phase diagram of the model analytically in the large Nf limit. We present an expression for the effective potential at tree-level in the regime of small Yukawa and quartic coupling constants and determine ...

Using numerical simulations, we investigate the equilibrium dynamics of a single-component fluid with Yukawa interaction potential. We show that, for a wide range of densities and temperatures, the dynamics of the system are in striking agreement with a simple model of generalized hydrodynamics. Since the Yukawa potential can describe the ion-ion interactions in a plasma, our results have signi...

Many alternative theories of gravity screen a Yukawa-type potential. This article shows Keplerian-type parametrization for the solution Yukawa type potential accurate equations motion two nonspinning compact objects moving in an eccentric orbit, using mean anomaly. From analytical some post-Keplerian parameters are derived. Consequently, bound from Solar System is presented.

We study local stability of self-gravitating fluid and stellar disk in the context of modified gravity theories which predict a Yukawa-like term in the gravitational potential of a point mass. We investigate the effect of such a Yukawa-like term on the dynamics of self-gravitating disks. More specifically, we investigate the consequences of the presence of this term for the local stability of t...

We determine the phase behavior of hard spheres interacting with repulsive Yukawa (screened Coulomb) interaction using computer simulations. We study the effect of the hard-core diameter on the phase behavior of repulsive Yukawa particles by comparing our phase diagrams with that of repulsive point Yukawa particles. We show that for sufficiently high contact values of the pair potential (betaep...

We systematically examine corrections to the gravitational inverse square law, which are due to compactified extra dimensions, and to higher-derivative R 2-terms in the effective gravitational action. We find that both induce Yukawa-type potentials for which we calculate the strength α and range. In general the range of the Yukawa correction is given by the wavelength of the lightest Kaluza–Kle...

The nature of the gravitational interaction between ordinary and dark matter is still open, and deviations from universality or Newtonian law may also modify the standard assumption of collisionless dark matter. On the other hand, obtaining a Yukawa-like large-distance modification of the gravitational potential is a nontrivial problem, that has so far eluded a consistent realization even at li...

Deviations from the 1/r 2 Newton law due to extra dimensions and α ′-corrections Abstract We systematically examine corrections to the gravitational inverse square law, which are due to compactified extra dimensions, and to higher-derivative R 2-terms in the effective gravitational action. We find that both induce Yukawa-type potentials for which we calculate the strength α and range. In genera...

Yukawa potentials are often used as effective potentials for systems as colloids, plasmas, etc. When the Debye screening length is large, the Yukawa potential tends to the non-screened Coulomb potential ; in this small screening limit, or Coulomb limit, the potential is long ranged. As it is well known in computer simulation, a simple truncation of the long ranged potential and the minimum imag...
