Abstract We developed an optical time-of-flight measurement system using a time-resolved and mode-selective up-conversion single-photon detector for acquiring tomographic images of a mouse brain. The probe and pump pulses were spectrally carved from

A space-time exchanged symplectic integrator (SI) method is developed to solve the three-wave resonance interaction equations commonly used in describing a number of fundamental nonlinear optical phenomena, such as second harmonic generation, optical

Field-induced transient current in one-dimensional nanostructures has been studied by a model of an electron confined in a 1D attractive Gaussian potential subjected both to electrodes at the terminals and to an ultrashort pulsed oscillatory electric

The stretch vibrations SO2 are studied by the Schmidt decomposition focusing on the normal- to local-mode transition that takes place in the highly excited vibrational states. The von Neumann entropy is calculated from the eigenvalues of the reduced

Transient current in transistor-like nanostructures has been studied by a model of a few electrons confined in a one-dimensional effective potential consisting of three quantum wells, 'source', 'gate', and 'drain'. The time-dependent Schrödinger equ

We studied the excitation dynamics of a finite quantum system with an intense optical near field (ONF) from a perspective of light-dressed states. A simple model consisting of a single electron and a nano-sized short dipole source were employed. By c

Using the model of cyclic polyenes $$\hbox {C}_N\hbox {H}_N$$ with a nondegenerate ground state, $$N = 4 \nu + 2 \; (\nu = 1, 2, \ldots )$$ , as a prototype of extended linear metallic-like systems we explore the cluster structure of the relevant wav

We formulate x-ray photoelectron diffraction (XPD) from molecules undergoing photochemical reactions induced by optical laser pulses, and then apply the formula to the simulation of time-dependent XPD profiles from both dissociating ${\mathrm{I}}_{2}
