The Flyby Anomaly and Options for Its Study,The geometrical phase in quantum mechanics discovered by Berry is not invariant under unitary transformations. It is generalized to be unitarily invariant and applicable to nonadiabatic and noncyclic systems. Examples of a spin-1/2 particle in a precessing magnetic field and a time-dependent generalized harmonic oscillator are considered.作者: Modify 時間: 2025-3-22 15:50

Decomposition of Signals and Information TheoryWe discuss a method that is able to determine, with the help of the Maximum Entropy Principle, the detailed nature of a complex signal that can be conceived as a linear superposition of independent, elementary signals. The physical relevance of this decomposition is discussed.作者: allude 時間: 2025-3-23 14:24
