Cluster quantum computer on the basis of quasi-part
The present paper deals with the possibility of creation of the quantum
computer in which the role of q-bits is played by quasi-particles. In such a
computer, the elementary computation block should represent a cluster created
on the basis of the paramagnetic molecules. The latter form heterogeneous spin
states in the cluster owing to the presence of interelectron correlations.Comment: 4 page
Q-phonon description of low lying 1^- two-phonon states in spherical nuclei
The properties of 1^-_1 two-phonon states and the characteristics of E1
transition probabilities between low-lying collective states in spherical
nuclei are analysed within the Q-phonon approach to the description of
collective states. Several relations between observables are obtained.
Microscopic calculations of the E1 0^+_1 -> 1^-_1 transition matrix elements
are performed on the basis of the RPA. A satisfactory description of the
experimental data is obtained.Comment: 16 pages, 2 figures, 9 table
On neutron number dependence of B(E1;0+ --> 1-) reduced transition probability
A neutron number dependence of the E1 0+ --> 1- reduced transition
probability in spherical even--even nuclei is analysed within the Q--phonon
approach in the fermionic space to describe the structure of collective states.
Microscopic calculations of the E1 0+ --> 1- transition matrix elements are
carried out for the Xe isotopes based on the RPA for the ground state wave
function. A satisfactory description of the experimental data is obtained.Comment: 8 pages, 4 figure
