My Warm, Randomly Recorded, Recollections of Professor Richard Askey

Sergei K. Suslov

These are my memories of moments with Dick and Liz Askey in Russia, Wisconsin, Arizona, and abroad. Dedicated to the Askey family, these recollections span over 40 years and encomp…

Schrodinger's Wave Mechanics: Remarkable Dates and Place One Hundred Years Ago

Sergei K. Suslov

We discuss, at a level accessible to a wide audience, including students and teachers of physics and mathematics, the fundamental transition from classical mechanics to wave equati…

Classification of Transuranium Elements in Terms of `Winding' Numbers in the Bohr-Sommerfeld Model

Sergei K. Suslov

We revisit the Bohr-Sommerfeld atomic model to explore hydrogen-like ions of Uranium (), Oganesson (), and hypothetical superheavy elements beyond. Although superseded…

Oganesson versus Uranium Hydrogen-like Ions and Beyond (from the Viewpoint of Old Quantum Mechanics)

Kamal Barley, Andreas Ruffing, Sergei K. Suslov

We compare, within the framework of the old Bohr-Sommerfeld atomic model, Uranium (Z=92) versus hypothetical Oganesson (Z=118) relativistic hydrogen-like ions and beyond. Existence…

Old Quantum Mechanics by Bohr and Sommerfeld from a Modern Perspective

Kamal K. Barley, Andreas Ruffing, Sergei K. Suslov

We review Bohr's atomic model and its extension by Sommerfeld from a mathematical perspective of wave mechanics. The derivation of quantization rules and energy levels is revisited…

The "Sommerfeld Puzzle" and Its Extensions

Sergei K. Suslov

The exact agreement between the Sommerfeld (1916) and Dirac (1928) results for the energy levels of the relativistic hydrogen atom (the so-called "Sommerfeld puzzle") is analyzed a…
