Some inequalities on generalized entropies
We give several inequalities on generalized entropies involving Tsallis
entropies, using some inequalities obtained by improvements of Young's
inequality. We also give a generalized Han's inequality.Comment: 15 page
Trace inequalities on a generalized Wigner-Yanase skew information
We introduce a generalized Wigner-Yanase skew information and then derive the
trace inequality related to the uncertainty relation. This inequality is a
non-trivial generalization of the uncertainty relation derived by S.Luo for the
quantum uncertainty quantity excluding the classical mixure. In addition,
several trace inequalities on our generalized Wigner-Yanase skew information
are argued
Quantum mutual entropy for Jaynes-Cummings model
The dynamics of an atom on the Jaynes-Cummings model has been studied by an
atomic inversion, von Neumann entropy and so on. In this letter, we will treat
the Jaynes-Cummings model as a problem in non-equilibrium statistical mechanics
and apply quantum mutual entropy to study the irreversible dynamics of a state
for the atom on this model.Comment: RevTeX, 4 pages with a figure(eps file), submitted to Physical Review
