Testing of two-dimensional local approximations in the current-spin and spin-density-functional theories
H. Saarikoski, E. Räsänen, S. Siljamäki +3
We study a model quantum dot system in an external magnetic field by using both the spin-density-functional theory and the current-spin-density-functional theory. The theories are…
Two-electron quantum dot molecule: Composite particles and the spin phase diagram
A. Harju, S. Siljamäki, R. M. Nieminen
We study a two-electron quantum dot molecule in a magnetic field by the direct diagonalization of the Hamiltonian matrix. The ground states of the molecule with the total spin S=0…
Various spin-polarization states beyond the maximum-density droplet: a quantum Monte Carlo study
S. Siljamaki, A. Harju, R. M. Nieminen +2
Using variational quantum Monte Carlo method, the effect of Landau-level mixing on the lowest-energy--state diagram of small quantum dots is studied in the magnetic field range whe…
Wigner molecules in quantum dots: a quantum Monte Carlo study
A. Harju, S. Siljamäki, R. M. Nieminen
We study two-dimensional quantum dots using the variational quantum Monte Carlo technique in the weak-confinement limit where the system approaches the Wigner molecule, i.e., the c…
