The most general two-order-parameter Ginzburg-Landau model with quadratic and quartic interactions
The Ginzburg-Landau model with two order parameters appears in many condensedmatter problems. However, even for scalar order parameters, the most general Landau potential with all quadratic and quartic terms contains 13 independent coefficients and cannot be minimized with the straightforward algebra. Here, we develop a geometric approach that circumventing this computational difficulty and all...
متن کاملGeneral two-order-parameter Ginzburg-Landau model with quadratic and quartic interactions.
The Ginzburg-Landau model with two-order parameters appears in many condensed-matter problems. However, even for scalar order parameters, the most general U(1)-symmetric Landau potential with all quadratic and quartic terms contains 13 independent coefficients and cannot be minimized with straightforward algebra. Here, we develop a geometric approach that circumvents this computational difficul...
متن کاملa Simplified Model of Distributed Parameter Systems
A generalized simplified model for describing the dynamic behavior of distributed parameter systems is proposed. The various specific characteristics of gain and phase angle of distributed parameter systems are investigated from frequency response formulation and complex plane representation of the proposed simplified model. The complex plane investigation renders some important inequality cons...
متن کاملBalanced model order reduction for systems depending on a parameter
We provide an analytical framework for balanced realization model order reduction of linear control systems which depend on an unknown parameter. Besides recovering known results for the first order corrections, we obtain explicit novel expressions for the form of second order corrections for singular values and singular vectors. The final result of our procedure is an order reduced model which...
متن کاملRequirements Engineering Model in Designing Complex Systems
This research tends to development of the requirements elicitation methodology with regard to operational nature and hierarchical analysis for complex systems and also, regarding available technologies. This methodology applies Analytic Hierarchy Process (AHP) and Analytic Network Process (ANP) to ensure traceability of planned qualitative and quantitative data from requirements to available te...
