Far-infrared spectra of lateral quantum dot molecules
M. Helle, A. Harju, R. M. Nieminen
We study effects of electron-electron interactions and confinement potential on the magneto-optical absorption spectrum in the far-infrared range of lateral quantum dot molecules.…
Interacting electrons on a quantum ring: exact and variational approach
S. S. Gylfadottir, A. Harju, T. Jouttenus +1
We study a system of interacting electrons on a one-dimensional quantum ring using exact diagonalization and the variational quantum Monte Carlo method. We examine the accuracy of…
Variational Monte Carlo for Interacting Electrons in Quantum Dots
Ari Harju
We use a variational Monte Carlo algorithm to solve the electronic structure of two-dimensional semiconductor quantum dots in external magnetic field. We present accurate many-body…
Two-electron lateral quantum-dot molecules in a magnetic field
M. Helle, A. Harju, R. M. Nieminen
Laterally coupled quantum dot molecules are studied using exact diagonalization techniques. We examine the two-electron singlet-triplet energy difference as a function of magnetic…
Ground-state of two-dimensional finite electron systems in the Quantum Hall regime
Henri Saarikoski, Ari Harju
We study electronic structures of quasi-two-dimensional finite electron systems in high magnetic fields. The solutions in the fractional quantum Hall regime are interpreted as quan…
