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…
Net current generation in a 1D quantum ring at zero magnetic field
Sigridur Sif Gylfadottir, Marian Nita, Vidar Gudmundsson +1
We study a non-adiabatic excitation of an electron system in a 1D quantum ring radiated by a short THz pulse. The response of two models, a continuous and discrete, is explored. By…
Non-adiabatic Current Excitation in Quantum Rings
S. S. Gylfadottir, V. Gudmundsson, C. S. Tang +1
We investigate the difference in the response of a one-dimensional semiconductor quantum ring and a finite-width ring to a strong and short-lived time-dependent perturbation in the…
