The RI-beam facilities in the new generation will increase significantly the number of experimentally accessible nuclei, especially in medium and heavy mass regions. We may reach nuclei close to the neutron drip-line in the 10 ≤ Z ≤ 20 and N ≥ 20 region, where a bunch of deformed neutron-rich nuclei are expected1. This will provide us with a new opportunity to study interplay among the presence...

in this paper, we calculate theoretically the relaxation rates of hot, thermal and antinodal quasiparticles by using fermi’s golden rule. the transition probabilities at low temperatures express in terms of bogoliubov coefficients, singlet and triplet scattering amplitudes and dimensionless landau parameters. the values of landau parameters may be determined by comparison with the experimental ...

Extending the qubit coherence times is a crucial task in building quantum information processing devices. In three-dimensional cavity implementations of circuit QED, superconducting qubits was improved dramatically due to cutting losses associated with photon emission. Next frontier improving includes mitigation adverse effects quasiparticles. these lectures, we review basics quasiparticles dyn...

Infinite sets of inequalities which generalize all the known inequalities that can be used in the majorization step of the Approximating Hamiltonian method are derived. They provide upper bounds on the difference between the quadratic fluctuations of intensive observables of a N -particle system and the corresponding BogoliubovDuhamel inner product. The novel feature is that, under sufficiently...

Considering the plasmon oscillation of each layer of the cell membranes as a quasi-particle, we introduce a simple model for the membrane collective charge excitations, take into account the surface effective potential of the plasmonplasmon interaction between two layers. By using the useful Bogoliubov transformation method, we easily obtained the expressions of the frequencies of plasmon oscil...

We show that in dilute boson-fermion mixtures with fermions in two internal states, even when the bare fermion-fermion interaction is repulsive, the exchange of density fluctuations of the Bose condensate may lead to an effective fermion-fermion attraction, and thus to a Cooper instability in the s-wave channel. We give an analytical method to derive the associated Tc in the limit where the pho...

General analytical procedure for determination of the transverse feedback system parameters with a nonlinear regime of injection oscillations damping in circular accelerators and colliders is described. For this feedback loop the dependence between the kick value in the deflector and the beam deviation at the pick-up location is a nonlinear function. The beam dynamic nonlinear equation of the t...
