The physics of time-odd mean fields
Wednesday, 19 May 2010, 15:30
Covariant density functional theory is well established theoretical
tool for the description of nuclear systems. However, there is still considerable
number of important problems which have not been either addressed or resolved
within its framework. In my talk, I will concentrate on one of them, namely,
the physics of time-odd mean fields.
Time-odd mean fields are related to nuclear magnetism in covariant density
functional theory. They arise from space-like components of vector mesons and
Lorentz invariance requires that their coupling strengths are identical to that
of time-like components. We performed systematic investigation of these fields
in non-rotating and rotating systems. The physics of these fields and physical
observables strongly affected by them will be discussed in detail.
