Permutationally invariant state reconstruction
(IOP Publishing, 2012-10)
Feasible tomography schemes for large particle numbers must possess, besides an appropriate data acquisition protocol, an efficient way to reconstruct the density operator from the observed finite data set. Since state ...
Subdiffusion of nonlinear waves in quasiperiodic potentials
(IOP Publishing, 2012-10-23)
We study the time evolution of wave packets in one-dimensional quasiperiodic lattices which localize linear waves. Nonlinearity (related to two-body interactions) has a destructive effect on localization, as observed ...
Black Holes, Cosmological Solutions, Future Singularities, and Their Thermodynamical Properties in Modified Gravity Theorie
(MDPI, 2012-09-18)
Along this review, we focus on the study of several properties of modified
gravity theories, in particular on black-hole solutions and its comparison with those solutions in General Relativity, and on Friedmann–Lemaˆıtr ...
The effects of disorder in dimerized quantum magnets in mean field approximations
(IOP Publishing LTD, 2012-11-07)
We study theoretically the effects of disorder on Bose-Einstein condensates (BEC) of bosonic triplon quasiparticles in doped dimerized quantum magnets. The condensation occurs in a magnetic field, where the concentration ...
Magnetization reversal and exchange bias effects in hard/soft ferromagnetic bilayers with orthogonal anisotropies
(IOP Publishing LTD, 2012-11-02)
The magnetization reversal processes are discussed for exchange-coupled ferromagnetic hard/soft bilayers made from Co0.66Cr0.22Pt0.12 (10 and 20 nm)/Ni (from 0 to 40 nm) films with out-of-plane and in-plane magnetic easy ...
Unconventional spin texture of a topologically nontrivial semimetal Sb(110)
(IOP Publishing LTD, 2012-10-17)
The surfaces of antimony are characterized by the presence of spin-split states within the projected bulk band gap and the Fermi contour is thus expected to exhibit a spin texture. Using spin-resolved density functional ...
Optimally robust shortcuts to population inversion in two-level quantum systems
(IOP Publishing LTD, 2012-09-21)
We examine the stability versus different types of perturbations of recently proposed shortcuts to adiabaticity to speed up the population inversion of a two-level quantum system. We find the optimally robust processes by ...
