将 |ψ(t)⟩ 用傅里叶级数(Fourier series)表示: |ψ(t)⟩=e−iεtℏ∑me−imωt|ϕ(m)⟩ 其中m 代表带边谐波(sideband harmonics), ω 是探测场的频率(frequency of the probing field)。 Floquet 光谱(也称作quasienergy spectrum)由单周期演化算符(one-period evolution operator)决定:...
You use a transform to switch between the domains. The Fourier Transform takes time domain data and generates the equivalent frequency domain data. The common term, FFT, refers to a fast, computerized implementation of the Fourier transform. The inverse Fourier transform changes frequency domain data...
The impedance is therefore expressed in terms of a magnitude, Zo, and a phase shift, Φ. If we plot the applied sinusoidal signal E(t) on the X-axis of a graph and the sinusoidal response signal I(t) on the Y-axis, the result is an oval (see Figure 2). This oval is known as...
Section 1.1 gives a brief survey of the canonical subject areas in physics, of physics history and the quantum nature of atomic phenomena. An introduction to orders of magnitude of length, time and energy follows. Section 1.2 summarizes some essentials o

The HB algorithm is very efficient and flexible and actually calculatesthe steady state solutiondirectly. It does this by using the Fourier series philosophy. HB is a pure frequency domain technique. We all know how the ac frequency domain runs get done with a minim...
