An analytical approach to symmetry breaking in multipole RF-traps

چکیده

Abstract Radio-frequency (RF) linear multipole traps have been shown to be very sensitive mis-positioning of their electrodes, which results in a symmetry breaking and leads extra local minima the trapping potential as Pedregosa-Gutierrez et al (2018 J. Mod. Opt. 65 529) disturbing operation trap. In this work, we analytically describe RF-potential realistic octupole trap by including lower order terms well-established equation for perfectly symmetric We geometry combination identified defects, characterized simple analytical expressions. A complete is proposed with any electrode deviation relying on cases where defects are taken individually. Our approach validated comparison between numerical defect sizes up 4% radius. As described Rev. Sci. Instrum. 89 123101), an independent fine-tuning amplitude RF voltage applied each can used mitigate geometrical different way than knowledge allows design set RF-voltages required compensation, based experimental measurement ion positions trap, without information concerning exact position electrode, small number iterations. The requirements, performances limitations protocol discussed via simulations results.

An approach to Symmetry Breaking in Distributed Constraint Satisfaction Problems

Symmetry breaking in Distributed Constraint Satisfaction Problems (DisCSPs) has, to the best of our knowledge, not been investigated. In this paper, we show that most symmetries in DisCSPs are actually weak symmetries, and we demonstrate howweak symmetry breaking techniques can be applied to DisCSPs.

An Analytical Approach to Persian Gulf Architecture

Rehabiliating Bushehr historic fabric and paying to it as an important urban fabric through increasing capabilities and facilities is main concern. Bushehr historical fabric can be the consequence of several factors the most important of which is the Persian Gulf and its past history as a national one. This fabric, is organic, dense, compact, having its own characteristics. One of its main prio...

An Introduction to Dynamical Electroweak Symmetry Breaking

While this theory is simple and renormalizable, it has a number of shortcomings. First, while the theory can be constructed to accommodate the breaking of electroweak symmetry, it provides no explanation for it – one simply assumes that the potential is of the form in eqn. 2. In addition, in the absence of supersymmetry, quantum corrections to the Higgs mass are naturally of order the largest s...
