Two-dimensional Bloch electrons in perpendicular magnetic fields: an exact calculation of the Hofstadter butterfly spectrum
S. Janecek, M. Aichinger, E. R. Hernandez
The problem of two-dimensional, independent electrons subject to a periodic potential and a uniform perpendicular magnetic field unveils surprisingly rich physics, as epitomized by…
Billiards in magnetic fields: A molecular dynamics approach
M. Aichinger, S. Janecek, E. Rasanen
We present a computational scheme based on classical molecular dynamics to study chaotic billiards in static external magnetic fields. The method allows to treat arbitrary geometri…
Geometric and impurity effects on quantum rings in magnetic fields
M. Aichinger, S. A. Chin, E. Krotscheck +1
We investigate the effects of impurities and changing ring geometry on the energetics of quantum rings under different magnetic field strengths. We show that as the magnetic field…
Stability of the shell structure in 2D quantum dots
M. Aichinger, E. Rasanen
We study the effects of external impurities on the shell structure in semiconductor quantum dots by using a fast response-function method for solving the Kohn-Sham equations. We pe…
