Dirac sextic oscillator in the constant magnetic field
Ramazan Koc, Mehmet Koca
We introduce a Dirac equation which reproduces the usual radial sextic oscillator potential in the non-relativistic limit. We determine its energy spectrum in the presence of the m…
A New Approach to Analyse Jahn-Teller System for
Ramazan Koc, Hayriye Tutunculer, Mehmet Koca
It is now well known that electron (hole)-vibron coupling and hence Jahn-Teller (JT) effect is important understanding the properties of and related molecules. In this pap…
Development of an approximate method for quantum optical models and their pseudo-Hermicity
Ramazan Koc
An approximate method is suggested to obtain analytical expressions for the eigenvalues and eigenfunctions of the some quantum optical models. The method is based on the Lie-type t…
Scattering in abrupt heterostructures using a position dependent mass Hamiltonian
Ramazan Koc, Mehmet Koca, Gultekin Sahinoglu
Transmission probabilities of the scattering problem with a position dependent mass are studied. After sketching the basis of the theory, within the context of the Schrödinger equa…
Maximal Subgroups of the Coxeter Group and Quaternions
Mehmet Koca, Ramazan Koc, Muataz Al-Barwani +1
The largest finite subgroup of O(4) is the noncrystallographic Coxeter group of order 14400. Its derived subgroup is the largest finite subgroup of SO(4…
Quaternionic Root Systems and Subgroups of the
Mehmet Koca, Ramazan Koc, Muataz Al-Barwani
Cayley-Dickson doubling procedure is used to construct the root systems of some celebrated Lie algebras in terms of the integer elements of the division algebras of real numbers, c…
