Effects of scarring on quantum chaos in disordered quantum wells
J. Keski-Rahkonen, P. J. J. Luukko, S. Åberg +1
The suppression of chaos in quantum reality is evident in quantum scars, i.e., in enhanced probability densities along classical periodic orbits, providing opportunities in control…
Polyatomic trilobite Rydberg molecules in a dense random gas
Perttu J. J. Luukko, Jan-Michael Rost
Trilobites are exotic giant dimers with enormous dipole moments. They consist of a Rydberg atom and a distant ground-state atom bound together by short-range electron-neutral attra…
Introducing libeemd: A program package for performing the ensemble empirical mode decomposition
P. J. J. Luukko, J. Helske, E. Räsänen
The ensemble empirical mode decomposition (EEMD) and its complete variant (CEEMDAN) are adaptive, noise-assisted data analysis methods that improve on the ordinary empirical mode d…
Strong quantum scarring by local impurities
Perttu J. J. Luukko, Byron Drury, Anna Klales +3
We discover and characterize strong quantum scars, or eigenstates resembling classical periodic orbits, in two-dimensional quantum wells perturbed by local impurities. These scars…
Imaginary time propagation code for large-scale two-dimensional eigenvalue problems in magnetic fields
P. J. J. Luukko, E. Räsänen
We present a code for solving the single-particle, time-independent Schrödinger equation in two dimensions. Our program utilizes the imaginary time propagation (ITP) algorithm, and…
Chaotic properties of Coulomb-interacting circular billiards
J. Solanpaa, J. Nokelainen, P. J. J. Luukko +1
We apply a molecular dynamics scheme to analyze classically chaotic properties of a two-dimensional circular billiard system containing two Coulomb-interacting electrons. As such,…
