Spin Configurations and Activation Gaps of the Quantum Hall States in Graphene
Tapash Chakraborty, Pekka Pietilainen
We report on our accurate evaluation of spin polarizations of the ground state and particle-hole gaps for partially-filled lowest Landau level, observed in recent experiments on gr…

Optical Signatures of Spin-Orbit Interaction Effects in a Parabolic Quantum Dot
Tapash Chakraborty, Pekka Pietiläinen
We demonstrate here that the dipole-allowed optical absorption spectrum of a parabolic quantum dot subjected to an external magnetic field reflects the inter-electron interaction e…

Symmetry breaking in driven and strongly damped pendulum
J. Isohätälä, K. N. Alekseev, L. T. Kurki +1
We examine the conditions for appearance of symmetry breaking bifurcation in damped and periodically driven pendulum in the case of strong damping. We show that symmetry breaking,…
