The eigenvalue spectrum in quantum mechanics and the nonlinearization procedure
TL;DR: In this paper, a perturbation theory which does not require knowledge of the entire eigenvalue spectrum of the unperturbed problem and uses a nonlinearization procedure was proposed.
Journal ArticleDOI
The normal modes of oscillation of a uniformly charged drop about its saddle-point shape
TL;DR: In this article, the normal modes of oscillation of an idealized uniformly charged axially symmetric liquid drop about its saddle-point shape and their frequencies as functions of the fissility parameter x were derived.
Journal ArticleDOI
The periodic table and the physics that drives it
TL;DR: The periodic table can be seen as a parallel to the Standard Model in particle physics, in which the elementary particles known today can be ordered according to their intrinsic properties as discussed by the authors, and the underlying fundamental theory to describe the interactions between particles comes from quantum theory or, more specifically, from quantum field theory and its inherent symmetries.

The Klein-Gordon equation with the Kratzer potential in d dimensions
TL;DR: In this paper, the bound-state energy spectrum for the d-dimensional Klein-Gordon equation with scalar S(r) and vector potentials V(r), where the potentials are Coulombic and Kratzer type, was obtained.

Superfluidity and phase transitions in a resonant Bose gas
TL;DR: In this paper, the atomic Bose gas is studied across a Feshbach resonance, mapping out its phase diagram, and computing its thermodynamics and excitation spectra, and it is shown that such a degenerate gas admits two distinct atomic and molecular superfluid phases, with the latter distinguished by the absence of atomic off-diagonal long-range order, gapped atomic excitations, and deconfined atomic π -vortices.
