Confined Klein–Gordon oscillator from a (2+1)-dimensional Gürses to a Gürses or a pseudo-Gürses space-time backgrounds: Invariance and isospectrality

Abstract: We study the Klein–shGordon (KG) oscillator with a Cornell-type scalar confinement in (2+1)-dimensional Gürses space-time backgrounds and report their exact solutions. The effect of the vorticity parameter $$\Omega $$ Ω on the energy levels is found to yield some interesting features like; energy levels-crossings, partial clustering of positive and negative energy levels, and shifting the energy gap upwards or downwards. Such confined KG-oscillators are also studied in a gene… Show more

“…Those equations are conditionally solvable and one obtains some particular polynomial solutions for particular values of the model parameters determined by a second condition overlooked by Mustafa. This conclusion also applies to another paper by the same author where he apparently derived exact results for a similar conditionally-solvable problem [10]. Most physical conclusions commonly derived from the polynomial solutions to conditionally-solvable eigenvalue equations are meaningless [2][3][4].…”

“…For both illustrative examples above, one should notice that the two KG-oscillators in (33) and (35) in the QPGM spacetime of (5) are invariant and isospectral with the KG-oscillators in (28) in the PGM spacetime of (3).…”

“…This would immediately result, in terms of the associated Laguerre polynomials ( ) as the exact eigen energies and eigen functions for the two dimensional Schr ödinger harmonic oscillator. Moreover, the same condition equation (35) should also be imposed on the biconfluent Heun function equation (33) so that a biconfluent Heun polynomial [43] of degree n = 2n r 0 is obtained (c.f., e.g., [23,41,44,45]) to imply…”
