It is stated by Ford and O'Connell in this festschrift issue and elsewhere that “there is no quantum regression theorem” although Lax “obtained a formula for correlation in a driven quantum system that has come to be called the quantum regressi

We consider an analytical solution of the time-dependent elastic Boltzmann transport equation in an infinite uniform isotropic medium with an arbitrary phase function. We obtain (1) the exact distribution in angle, (2) the exact first and second spat

The image of an object hidden in highly scattering media was reconstructed using a fast, noise-resistant algorithm newly applied to diffusion tomography. A pulsed light source producing scattered and transmitted light is examined at multiple times. M

We develop a general theory for noise fluctuations in open optical systems with gain or loss based on an expansion in terms of nonorthogonal quasimodes. Spatial variation of the index of refraction and of the gain are taken into account. We show that

An approach to the theory of electron energy transport between randomly situated donors, based on expanding the kinetic equations valid for fixed donor space positions into a spatial Fourier series and neglecting the interaction betwen different Four

To deal with sharply cut off fields at mirror edges, a continuous Fourier integration procedure is described. A spline fit is made to the discrete data, followed by analytic integration of the spline functions. End corrections associated with the dif

The high-frequency (HF) current, induced by a HF signal, through a double-barrier tunneling device is shown to have wavelike characteristics, with a wavelength much smaller than that of the signal. The wave behavior of the HF current originates from

We propose two approaches to study the electron tunneling including inelastic scattering. Our calculation shows some interesting inelastic-scattering-assisted resonances in tunneling.
