Random matrix ensemble with random two-body interactions in the presence of a mean field for spin-one boson systems
Random matrix ensemble with random two-body interactions in the presence of a mean field for spin-one boson systems
For bosons carrying spin-one degree of freedom, we introduce an embedded Gaussian orthogonal ensemble of random matrices generated by random two-body interactions in the presence of a mean field that is spin ($S$) scalar [called BEGOE(1+2)-$S1$]. Embedding algebra for the ensemble, for $m$ bosons in $\ensuremath{\Omega}$ number of single-particle levels …
