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 ...

Comment on: “Entanglement in three coupled oscillators” [Phys. Lett. A 384 (2020) 126134]
(Elsevier, 2020-09-07)
In this comment we analyze a method for the solution of the eigenvalue equation for three coupled harmonic oscillators proposed recently. We argue that the authors did not obtain the frequencies and coordinates of the ...
Symmetry breaking, Josephson oscillation and self-trapping in a self-bound three-dimensional quantum ball
(2017-12-01)
We study spontaneous symmetry breaking (SSB), Josephson oscillation, and self-trapping in a stable, mobile, three-dimensional matter-wave spherical quantum ball self-bound by attractive two-body and repulsive three-body ...
Highly accurate calculation of the real and complex eigenvalues of one-dimensional anharmonic oscillators
(Czech Technical University, 2017-01)
We draw attention on the fact that the Riccati-Padé method developed some time ago enables the accurate calculation of bound-state eigenvalues as well as of resonances embedded either in the continuum or in the discrete ...
Two-Weight Norm Inequalities for the Local Maximal Function
(Springer, 2017-01)
For a local maximal function defined on a certain family of cubes lying “well inside” of Ω , a proper open subset of Rn, we characterize the couple of weights (u, v) for which it is bounded from Lp(v) on Lq(u).
From the generalized Morse potential to a unified treatment of the D-dimensional singular harmonic oscillator and singular Coulomb potentials
(Springer, 2016-10-01)
Bound-state solutions of the singular harmonic oscillator and singular Coulomb potentials in arbitrary dimensions are generated in a simple way from the solutions of the one-dimensional generalized Morse potential. The ...
