One dimensional Hydrogen problem with general connection condition at the origin and non-Rydberg spectra
Axel Pérez-Obiol, Taksu Cheon
We consider the solution of the quantum Coulomb problem in one dimension with the most general connection condition at the origin. The divergence of the derivative of the wave func…
Bose-Einstein condensate confined in a 1D ring stirred with a rotating delta link
Axel Pérez-Obiol, Taksu Cheon
We consider a Bose-Einstein condensate with repulsive interactions confined in a 1D ring where a Dirac delta is rotating at constant speed. The spectrum of stationary solutions in…
Stationary real solutions of the nonlinear Schrödinger equation on a ring with a defect
Axel Pérez-Obiol, Taksu Cheon
We analyze the 1D cubic nonlinear stationary Schrödinger equation on a ring with a defect for both focusing and defocusing nonlinearity. All possible and boundary conditio…
One-loop contributions in the EFT for the transition
Axel Pérez-Obiol, David R. Entem, Bruno Juliá-Díaz +1
We consider the weak transition, responsible for a large fraction of the non-mesonic weak decay of hypernuclei. We follow on the previously derived effective field theor…
