Time-evolved numerical simulation of a two-dimensional electron wave packet through a quantum point contact

Akira Endoh, Shigehiko Sasa, Shunichi Muto

We performed time-evolved numerical simulation of a two-dimensional electron wave packet through a quantum point contact using the finite difference method to simulate the diffraction phenomenon of a single electron. We found that the transmitted wave packet has diffracted subpeaks which show the following properties: (1) The traces of diffracted subpeaks start from the center of the slit entrance. (2) Lateral wave number of diffracted subpeaks is quantized. (3) The diffraction angles are determined by slit width and the initial electron wave packet energy. (4) The number of allowed diffracted subpeaks is determined by potential barrier thickness. (5) There is a delay in the motion of diffracted subpeaks due to quantization inside the slit.

Time-evolved numerical simulation of a two-dimensional electron wave packet through a quantum double slit

Akira Endoh, Shigehiko Sasa, Hiroshi Arimoto +1 more

We performed time-evolved numerical simulation of a two-dimensional electron wave packet through a double slit by solving the time-dependent Schrödinger equation using the finite difference method to simulate the electron interference phenomenon of a single electron. The propagating directions of interference peaks show that the starting point of electron interference is the center between the two slit exits. The number of interference peaks and their angles are found to be independent of potential barrier thickness. These results are compared with the results of our previous calculation of electron diffraction through a single slit.

A versatile applet to explore the wave behaviour of particles

José Ignacio Fernández Palop

A pedagogical tool that consists of a Java applet has been developed so that undergraduate students in physics can explore the wave behaviour of particles. The applet executes a simulation in which a two-dimensional wave packet moves towards a slit and an obstacle with variable widths. By changing three parameters, slit width, obstacle width and initial position of the wave packet, different behaviour can be explored such as interference, diffraction produced by a slit, a corner and an obstacle, and bouncing of the wave packet, etc. The usefulness of the applet has been tested in the subject of quantum physics.
