Lower bounds on par with upper bounds for few-electron atomic energies
Miklos Ronto, Peter Jeszenszki, Edit Mátyus +1
The development of computational resources has made it possible to determine upper bounds for atomic and molecular energies with high precision. Yet, error bounds to the computed e…
Improvements to Kramers Turnover Theory
Eli Pollak, Joachim Ankerhold
The Kramers turnover problem, that is obtaining a uniform expression for the rate of escape of a particle over a barrier for any value of the external friction was solved in the ei…
Imaginary time Gaussian dynamics of the Ar_3 cluster
Holger Cartarius, Eli Pollak
Semiclassical Gaussian approximations to the Boltzmann operator have become an important tool for the investigation of thermodynamic properties of clusters of atoms at low temperat…
Heavy atom quantum diffraction by scattering from surfaces
Jeremy M. Moix, Eli Pollak
Typically one expects that when a heavy particle collides with a surface, the scattered angular distribution will follow classical mechanics. The heavy mass assures that the de Bro…
