Berry phase and spin precession without magnetic fields in semiconductor quantum dots

Prabhakar, S.; Melnik, R. (2019)

We investigate electric field control of spin manipulation through Berry phase in III-V semiconductor quantum dots. By utilizing degenerate and non-degenerate perturbation theories, we diagonalize the total Hamiltonian of ...
Coupled magneto-thermo-electromechanical effects and electronic properties of quantum dots

Prabhakar, S.; Melnik, R.; Neittaanmäki, P.; Tiihonen, T. (2013-12-31)

For the first time, we systemically analyze the influence of magneto-thermo-electromechanical effects on the band structure calculations by using the fully coupled model. We focus on three different types of quantum dots ...
