Stationary and nonstationary scalar vacuum field noises
H. C. Rosu
If stationary, the spectrum of vacuum field noise (VFN) is an important ingredient to get information about the curvature invariants of classical worldlines (relativistic classical…
An Ermakov study of Q not zero EFRW minisuperspace oscillators
H. C. Rosu, P. Espinoza
A previous work on the Ermakov approach for empty FRW minisuperspace universes of Hartle-Hawking factor ordering parameter Q=0 is extended to the Q not zero cases
Hydrogen atom as an eigenvalue problem in 3D spaces of constant curvature and minimal length
L. M. Nieto, H. C. Rosu, M. Santander
An old result of A.F. Stevenson [Phys. Rev.} 59, 842 (1941)] concerning the Kepler-Coulomb quantum problem on the three-dimensional (3D) hypersphere is considered from the perspect…
Quantum mechanical spectral engineering by scaling intertwining
D. J. Fernandez C., H. C. Rosu
Using the concept of spectral engineering we explore the possibilities of building potentials with prescribed spectra offered by a modified intertwining technique involving operato…
Ermakov approach for Q=0 empty FRW minisuperspace oscillators
H. C. Rosu, P. Espinoza, M. Reyes
The Wheeler-DeWitt equation for empty FRW minisuperspace universes of Hartle-Hawking factor ordering parameter Q=0 is mapped onto the dynamics of a unit mass classical oscillator.…
Classical Mechanics
H. C. Rosu
This is the English version of a friendly graduate course on Classical Mechanics, containing about 80% of the material I covered during the January-June 1999 semester at IFUG in th…
