Operators of Dirac's theory with mass and axial chemical potential
Ion I. Cotaescu
The Dirac equation with mass and axial chemical potential is solved analytically obtaining the mode spinors and corresponding projection operators giving the spectral representatio…
Maxwell-Juttner distribution for rigidly-rotating flows in spherically symmetric spacetimes using the tetrad formalism
Victor E. Ambrus, Ion I. Cotaescu
We consider rigidly rotating states in thermal equilibrium on static spherically symmetric spacetimes. Using the Maxwell-Juttner equilibrium distribution function, onstructed as a…
Infinite loop superalgebras of the Dirac theory on the Euclidean Taub-NUT space
Ion I. Cotaescu, Mihai Visinescu
The Dirac theory in the Euclidean Taub-NUT space gives rise to a large collection of conserved operators associated to genuine or hidden symmetries. They are involved in interestin…
Remarks on the spherical waves of the Dirac field on de Sitter spacetime
Ion I. Cotăescu, Radu Racoceanu, Cosmin Crucean
The Shishkin's solutions of the Dirac equation in spherical moving frames of the de Sitter spacetime are investigated pointing out the set of commuting operators whose eigenvalues…
Superalgebras of Dirac operators on manifolds with special Killing-Yano tensors
Ion I. Cotăescu, Mihai Visinescu
We present the properties of new Dirac-type operators generated by real or complex-valued special Killing-Yano tensors that are covariantly constant and represent roots of the metr…
Symmetries and supersymmetries of the Dirac operators in curved spacetimes
I. I. Cotaescu, M. Visinescu
It is shown that the main geometrical objects involved in all the symmetries or supersymmetries of the Dirac operators in curved manifolds of arbitrary dimensions are the Killing v…
