On the SU(3) parametrization of qutrits
A. T. Bolukbasi, T. Dereli
Parametrization of qutrits on the complex projective plane CP^2 = SU(3)/U(2) is given explicitly. A set of constraints that characterize mixed state density matrices is found.
Dualisation of the Symmetric Space Sigma Model with Couplings
Tekin Dereli, Nejat T. Yilmaz
The first-order formulation of the G/K symmetric space sigma model of the scalar cosets of the supergravity theories is discussed when there is coupling of (m-1)-form matter fields…
Solutions of the Gaudin Equation and Gaudin Algebras
A. B. Balantekin, T. Dereli, Y. Pehlivan
Three well-known solutions of the Gaudin equation are obtained under a set of standard assumptions. By relaxing one of these assumptions we introduce a class of mutually commuting…
Exactly Solvable Pairing Model Using an Extension of Richardson-Gaudin Approach
A. B. Balantekin, T. Dereli, Y. Pehlivan
We introduce a new class of exactly solvable boson pairing models using the technique of Richardson and Gaudin. Analytical expressions for all energy eigenvalues and first few ener…
