The properties of choline chloride plus phenylacetic acid deep eutectic solvents in neat liquid state and upon absorption of CO2 are analyzed using a theoretical approach combining quantum chemistry using Density Functional ...
Asymptotic freedom, dimensional transmutation, and an infrared conformal fixed point for the ? -function potential in one-dimensional relativistic quantum mechanics
(
American Physical Society
, 2014 , Article)
We consider the Schr?dinger equation for a relativistic point particle in an external one-dimensional ?-function potential. Using dimensional regularization, we investigate both bound and scattering states, and we obtain ...
