Single-particle momentum distributions of Efimov states in mixed-species systems
(2013-06-04)
We solve the three-body bound-state problem in three dimensions for mass imbalanced systems of two identical bosons and a third particle in the universal limit where the interactions are assumed to be of zero range. The ...
Pseudospin and spin symmetries in the relativistic harmonic oscillator
(2006-12-01)
We compute the analytical solutions of the generalized relativistic harmonic oscillator in 1+1 dimensions, including a linear pseudoscalar potential and quadratic scalar and vector potentials which have equal or opposite ...

Exact correlation functions in particle-reaction models with immobile particles
(IOP PUBLISHING LTDBRISTOL, 2012)
Exact results on particle densities as well as correlators in two models of immobile particles, containing either a single species or else two distinct species, are derived. The models evolve following a descent dynamics ...
Light-particle single ionization of argon: Influence of the projectile charge sign
(American Physical Society, 2009-07)
The ionization of the 3p orbital of argon by incident electrons and positrons is studied by means of the post version of the continuum distorted wave–eikonal initial-state model. Results are presented at both 200 and 500 ...
Radiative capture of nucleons at astrophysical energies with single-particle states
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2010)
Radiative capture of nucleons at energies of astrophysical interest is one of the most important processes for nucleosynthesis. The nucleon capture can occur either by a compound nucleus reaction or by a direct process. ...
Work done on a single-particle gas during an adiabatic compression and expansion process
We compute the average work done by an external agent, driving a piston at constant speed, over a single-particle gas going through an adiabatic compression and expansion process. To do so, we get the analytical expression ...
