Abstract While engineered quantum systems are a general route to the manipulation of multipartite states, access in physical system continuous phase transition under sufficient control offers possibility an intrinsic source entangled states. To this end we realize version linear-zigzag structural for arrays up five ground state-cooled ions held linear Paul trap and demonstrate several requireme...

Experimental and simulation study of RF modes were carried out for the complicated geometry of the shielded vertex bellows near the IP region of the PEP-II B-factory. A beam position monitor button electrode located 50 cm from the bellows provides a signal for spectrum measurement. Calculations indicate monopole, dipole and quadrupole modes can exist in the bellows structure near the experiment...

NBO analysis, hybrid density functional theory (B3LYP/6-311+G**) and ab initio molecular orbital (HF/6-311+G**) based methods were used to study the anomeric effects (AE), electrostatic interactions, dipole-dipole interactions and steric repulsion effects on the conformational properties of 2-methoxy- (1), 2-methylthio- (2), 2-methylseleno- (3), 2-fluoro- (4), 2-chloro- (5) and 2-bromocyclohexa...

theoretically predictionq of the solvent effects of i - pentadecanoyl - 2 -docosahexaennyl - sn - glycerol3 - phosphocholin have been studied using 'jamey-lock quantiun chemical approximation and std - 30basis set within the onsager self-consistent reaction field (scrs') model all optimized conformers of i -pentadecanoyl - 2 -docosahexaenoyi - sn - glycerol 3 - phosphocholin as well as their to...

We study the coherent spin-polarized transport through a zigzag-edge graphene flake (ZGF), using Hubbard model in the nearest neighbor approximation within the framework of the Green function’s technique and Landauer formalism. The system considered consists of electrode/ (ZGF)/electrode, in which the electrodes are chosen to be armchair nanoribbons. The study was performed for two types of ele...

We investigate various magnetic configurations caused by the dipole--dipole interaction in thin-film magnets with perpendicular anisotropy under open boundary conditions. Two different approaches are simulated: one starts from a random configuration and decreases temperatures stepwisely; other saturated out-of-plane ferromagnetic state to evaluate its metastability. As typical patterns of confi...

A consistently effective transvenous defibrillation system for use in automatic defibrillators could significantly alter the approach to patients at risk of sudden death. Transvenous defibrillation systems that use a right ventricular (RV) electrode only or an RV electrode in combination with a chest patch are relatively inefficient at applying current to the posterolateral left ventricle. An R...
