Electronic structure of nanorod of strongly prolate ellipsoidal shape
T. Kereselidze, T. Tchelidze, T. Nadareishvili
A charged particle (electron or hole) confined in nanorod of strongly prolate ellipsoidal shape is considered. The effective-mass Schrödinger equation is solved in prolate spheroid…
Generalization of the hypervirial and Feynman-Hellman theorems
Teimuraz Nadareishvili, Anzor Khelashvili
Using well-known methods we generalize (hyper)virial theorems to case of singular potential. Discussion is carried on for most general second order differential equation, which inv…
Why Professor Richard Feynman was upset solving the Laplace equation for spherical waves?
Anzor Khelashvili, Teimuraz Nadareishvili
We take attention to the singular behavior of the Laplace operator in spherical coordinates, which was established in our earlier work. This singularity has many non-trivial conseq…
