- Abstract summary: We present a numerical study of the electronic transport properties of metallic nanotubes deviating from the cylindrical form.
It is found that the nanotube may be used as an energy high-pass filter for electrons.
It is also shown that the device can be used to tune the angular momentum of transmitted electrons.

- Abstract: The investigation of curved low-dimensional systems is a topic of great
research interest. Such investigations include two-dimensional systems with
cylindrical symmetry. In this work, we present a numerical study of the
electronic transport properties of metallic nanotubes deviating from the
cylindrical form either by having a bump or a depression, and under the
influence of a magnetic field. Under these circumstances, it is found that the
nanotube may be used as an energy high-pass filter for electrons. It is also
shown that the device can be used to tune the angular momentum of transmitted
electrons.

surface-state electrons [16.155892979947115]
We propose a quantum sensor to sensitively detect the electric field of the millimeter (mm) wave.
The quantum sensor consists of many surface-state electrons trapped individually on liquid helium.
The electric field of the applied mm wave could be detected sensitively by using the spin-echo interferometry of the long-lived spin states of the electrons trapped on liquid helium.
