Two Schrödinger-like Equations for hadrons

In this talk, based on [1, 2], I argue that the holographic Schrödinger Equation of (3 +1)-dim, conformal light-front QCD and the ’t Hooft Equation of (1+1)-dim, large Nc QCD, can be complementary to each other in providing a first approximation to hadron spectroscopy. Together, the two equations play a role in hadronic physics analogous that of the ordinary Schrödinger Equation in atomic physics.

Strong-field atomic physics meets $^{229}$Th nuclear physics

We show how two apparently unrelated research areas, namely, strong-field atomic physics and $^{229}$Th nuclear physics, are connected. The connection is possible due to the existence of a very low-lying excited state of the $^{229}$Th nucleus, which is only about 8 eV above the nuclear ground state. The connection is physically achieved through an electron recollision process, which is the core process of strong-field atomic physics. The laser-driven recolliding electron is able to excite the nucleus, and a simple model is presented to explain this recollision-induced nuclear excitation (RINE) process. The connection of these two research areas provides novel opportunities for each area and intriguing possibilities from the direct three-partite interplay between atomic physics, nuclear physics, and laser physics.

Oleg Zatsarinny: Expert Atomic Theorist, Kind Man

I met Oleg Zatsarinny in 2001, and he then worked with me at Western Michigan University for two years. From 2003 to 2013, we were coauthors of 15 papers on theoretical atomic physics, and maintained a friendly relationship over twenty years, meeting and socializing often at conferences. Further elaboration follows below.

Development of a cold atomic muonium beam for next generation atomic physics and gravity experiments

A high-intensity, low-emittance atomic muonium (M =\mu^+ + e^-=μ++e−) beam is being developed, which would enable improving the precision of M spectroscopy measurements, and may allow a direct observation of the M gravitational interaction. Measuring the free fall of M atoms would be the first test of the weak equivalence principle using elementary antimatter (\mu^+μ+) and a purely leptonic system. Such an experiment relies on the high intensity, continuous muon beams available at the Paul Scherrer Institute (PSI, Switzerland), and a proposed novel M source. In this paper, the theoretical motivation and principles of this experiment are described.

A Review of the Bohr’s Model of Hydrogen Atom

In this paper, the classical Bohr’s model of the hydrogen atom has been revisited. Two values of fundamental physical properties of an electron in the hydrogen atom has been identified. These physical properties ( & ) are constant in nature. The aim for the review was to contribute to the solution of disagreement between the Bohr’s wavelength ( ) and the Balmer’s experimental observation ( ) for the emission spectrum of hydrogen atom. There are two other constants and that were identified in the Bohr’s equation of the hydrogen atom. The four fundamental physical constants are intrinsic properties of an electron and can be applied to multi-electron system. They can also be obtained from Schrodinger’s equation for hydrogen atom at steady state. These constants may be subjected to scrutiny for their determination for better understanding. Also, since Bohr’s model of hydrogen atom is based on classical mechanics, this paper has provided an alternate method of solving simple problems in atomic physics under Bohr’s model to aid good mental picture of hydrogen atom to scientists.

Essays in Physics

“Essays in Physics” gives accounts of 32 chosen topics. The level is that of a 3–4-year university course in Physics. The topics discussed are diverse but “mainstream”. Each essay aims to say something fresh that complements what the reader will find elsewhere. Just what “fresh” means inevitably depends somewhat on the subject matter. Some chapters give a “different” slant on a familiar idea (e.g. electromagnetic energy, Lorentz transformation, photon emission). Some contain an analysis not available elsewhere (diffraction, feedback stability). Some correct material that is commonplace in many textbooks (much atomic physics). Some add insightful discussion to standard material (free energy, Brillouin zones). One in particular refines technique (perturbation theory). One brings order to confusion (-m dB). The aim in all cases is to encourage a fuller, and correct, understanding, and an enhanced intellectual acuity (critical faculty). With a subject as mature as physics, it is bold to claim originality. However I will dare to make that claim, in particular for Chapters 10, 22 and 30, but also for parts of most other chapters.
