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.

The structure of organization of the political body in the conception of Hannah Arendt
Filosofia Unisinos, 2021 This study focuses on the investment in the systems of councils or other forms of spontaneous political manifestation, in which Arendt (1990) presents a conception of a political body inserted into local problems, thus, becoming the basic problems of ...

Infinite-body optimal transport with Coulomb Cost [PDF]
, 2013 We introduce and analyze symmetric infinite-body optimal transport (OT) problems with cost function of pair potential form. We show that for a natural class of such costs, the optimizer is given by the independent product measure all of whose factors are

Collision dynamics in Hénon-Heiles’ two-body problem [PDF]
Serbian Astronomical Journal, 2003 We tackle the two-body problem associated to Hénon-Heiles’ potential in the special case of the collision singularity. Using McGehee-type transformations of the second kind, we blow up the singularity and replace it by the collision manifold Mc pasted on

Relativistic Two-Body Problem [PDF]
Progress of Theoretical Physics, 1952 Since the recent improvements of the quantum field theories have made possible to perform extensive calculations relativistically, these elegant techniques have been applied to the open systems by many authors. However, no relativistic treatment of bound systems has been made as yet except for Heisenberg-M¢ller's S-matrix theory (1) (2), and an ...

Do students use and understand free-body diagrams?
Physical Review Special Topics. Physics Education Research, 2009 Physics education literature recommends using multiple representations to help students understand concepts and solve problems. However, there is little research concerning why students use the representations and whether those who use them are more ...

Planar Central Configurations of Symmetric Five-Body Problems with Two Pairs of Equal Masses
Advances in Astronomy, 2016 We study central configuration of a set of symmetric planar five-body problems where (1) the five masses are arranged in such a way that m1, m2, and m4 are collinear and m2, m3, and m5 are collinear; the two sets of collinear masses form a triangle with ...

Four-Body Bound State Formulation in Three-Dimensional Approach (Without Angular Momentum Decomposition) [PDF]
, 2006 The four-body bound state with two-body forces is formulated by the Three-Dimensional approach, which greatly simplifies the numerical calculations of few-body systems without performing the Partial Wave components.
