The spectrum of O in terms of the multiconfigurational dynamical symmetry
Gábor Riczu, Chandra Sekhar Panda, Géza Lévai +1
Background: The experimental study of the Li-transfer reaction and alpha-scattering resulted in a rich spectrum of O, including some strong indication for band structu…
Renormalization of coherent state variables, within the geometric mapping of algebraic models
H. Yépe-Martínez, G. Morales-Hernández, P. O. Hess +2
We investigate the geometrical mapping of algebraic models. As particular examples we consider the Semimicriscopic Algebraic Cluster Model (SACM) and the Phenomenological Algebraic…
Schroedinger equations with indefinite effective mass
Miloslav Znojil, Géza Lévai
The consistency of the concept of quantum (quasi)particles possessing effective mass which is both position- and excitation-dependent is analyzed via simplified models. It is shown…
Phenomenological and microscopic cluster models II. Phase transitions
P. R. Fraser, H. Yépez-Martínez, P. O. Hess +1
Based on the results of a previous paper (Paper I), by performing the geometrical mapping via coherent states, phase transitions are investigated and compared within two algebraic…
Phenomenological and microscopic cluster models I. The geometric mapping
H. Yépez-Martínez, P. R. Fraser, P. O. Hess +1
The geometrical mapping of algebraic nuclear cluster models is investigated within the coherent state formalism. Two models are considered: the Semimicroscopic Algebraic Cluster Mo…
Asymptotically vanishing PT-symmetric potentials and negative-mass Schroedinger equations
Miloslav Znojil, Petr Siegl, Géza Lévai
In paper I [M. Znojil and G. Lévai, Phys. Lett. A 271 (2000) 327] we introduced the Coulomb - Kratzer bound-state problem in its cryptohermitian, PT-symmetric version. An instabili…
Comprehensive analysis of conditionally exactly solvable models
Rajkumar Roychoudhury, Pinaki Roy, Miloslav Znojil +1
We study a quantum mechanical potential introduced previously as a conditionally exactly solvable (CES) model. Besides an analysis following its original introduction in terms of t…
