Einstein's Hydrogen Atom [PDF]
2011 International Conference on Multimedia Technology, 2011 In 1905, Einstein formulated his special relativity for point particles. For those particles, his Lorentz covariance and energy-momentum relation are by now firmly established. How about the hydrogen atom?

Coherent States for the Hydrogen Atom [PDF]
Journal of Physics A: Mathematical and General, 1995 The long-standing problem of finding coherent states for the (bound state portion of the) hydrogen atom is positively resolved. The states in question: (i) are normalized and are parameterized continuously, (ii) admit a resolution of unity with a ...

On-Surface Synthesis with Atomic Hydrogen [PDF]
ACS Nano, 2020 Surface-assisted synthesis has become a powerful approach for generation of molecular nanostructures, which could not be obtained via traditional solution chemistry. Nowadays there is an intensive search for reactions that could proceed on flat surfaces in order to boost the versatility and applicability of synthesized nano-objects.
