The Araki–Lieb inequality is commonly used to calculate the entropy of subsystems when
they are initially in pure states, as this forces the entropy of the two subsystems to be equal …

It is shown that, in the interaction of a field and a qubit, there exists a relation between the
linear entropy and the von Neumann entropy. The Cayley–Hamilton theorem is used to …

We investigate some of the fundamental features of the interaction of a mixture of coherent
states, namely, a Kaleidoscope states mixture, with two-level atoms in the Jaynes …

We study the atom-field interaction at finite temperature and in the dispersive regime. We
show that the master equation for this sytem may be solved with the use of superoperator …

Abstract We study the Jaynes-Cummings model with initial mixed states, for the atom or the
field, are considered. The evolved mixed field density matrix is purified to a wavefunction …

We study the atom-field interaction at finite temperature and in the dispersive regime. We
show that the master equation for this sytem may be solved with the use of superoperator …

We investigate some of the fundamental features of the interaction of mixed kaleidoscope
states, namely, particular statistical mixtures of coherent states, with two-level atoms in the …
