摘要:The present work aims to control the rotational excitations of an ac-driven planar rotor, a model for rigid diatomic molecules, by rebuilding barriers in the classical phase space. The barriers are invariant tori with irrational winding ratios which are perturbatively constructed...

摘要:... We investigate the existence and uniqueness of solutions to NSFDEwLJs at the phase space \(C_{g}\) under the local Carathéodory type conditions. Meanwhile, we also give the exponential estimates and almost surely asymptotic estimates of solutions to NSFDEwLJs.

摘要:... In this paper, a novel blind bandwidth extension method is proposed based on phase space reconstruction. Phase space reconstruction is introduced to convert the low-frequency modified discrete cosine transform coefficients of wideband audio to a multi-dimensional space, and t...

摘要:Based on phase space reconstruction and fractal dynamics in nonlinear dynamics, a method is proposed to extract and analyze the dynamics of the rotating stall in the impeller of centrifugal compressor, and some numerical examples are given to verify the results as well. Firs...

摘要:In this paper we study the effects of noncommutative phase space deformations on the Schwarzschild black hole. This idea has been previously studied in Friedmann–Robertson–Walker (FRW) cosmology, where this “noncommutativity” provides a simple mechanism that can explai...

摘要:Abstract(#br)In this paper, we consider the Dirac equation in two dimensions influenced by an energy-dependent potential within a non-commutative phase space (NCP) framework for which no clear and reasonable solution has been given until now. By using the Nikiforov–Uvarov meth...

摘要:... We discuss the eigenvalues of q-deformed Dirac oscillator in (1+2)-dimensions in the presence of a magnetic field in a Noncommutative phase space formalism.

摘要:We consider scale transformations (q, p) → (λq, λp) in phase space. They induce transformations of the Husimi functions H(q, p) defined in this space. We consider the Husimi functions for states that are arbitrary superpositions of n-particle states of a harmonic oscillator...

摘要:Abstract(#br)A non-Noether conserved quantity for the differential equations of motion of mechanical systems in the phase space is studied. The differential equations of motion of the systems are established and the determining equations of Lie symmetry are given. An existence th...

摘要:... For these reasons, we first modify the so-called reduced phase space method, in which a continuous wavefront mapping method is implemented for efficient and accurate consideration, and then compare it with two newly developed grid-based algorithms for tracing multi-valued ...
