Optical properties of graphene antidot lattices
Thomas G. Pedersen, Christian Flindt, Jesper Pedersen +3
Undoped graphene is semi-metallic and thus not suitable for many electronic and optoelectronic applications requiring gapped semiconductor materials. However, a periodic array of h…
Graphene Antidot Lattices - Designed Defects and Spin Qubits
Thomas G. Pedersen, Christian Flindt, Jesper Pedersen +3
Antidot lattices, defined on a two-dimensional electron gas at a semiconductor heterostructure, are a well-studied class of man-made structures with intriguing physical properties.…
Spin qubits in antidot lattices
Jesper Pedersen, Christian Flindt, Niels Asger Mortensen +1
We suggest and study designed defects in an otherwise periodic potential modulation of a two-dimensional electron gas as an alternative approach to electron spin based quantum info…
Designed defects in 2D antidot lattices for quantum information processing
Jesper Pedersen, Christian Flindt, Niels Asger Mortensen +1
We propose a new physical implementation of spin qubits for quantum information processing, namely defect states in antidot lattices defined in the two-dimensional electron gas at…
Failure of standard approximations of the exchange coupling in nanostructures
Jesper Pedersen, Christian Flindt, Niels Asger Mortensen +1
We calculate the exchange coupling for a double dot system using a novel, numerically exact yet efficient technique, based on finite-element methods. Specifically, we evaluate the…
Universal spin-polarization fluctuations in 1D wires with magnetic impurities
N. A. Mortensen, J. C. Egues
We study conductance and spin-polarization fluctuations in one-dimensional wires with spin-5/2 magnetic impurities (Mn). Our tight-binding Green function approach goes beyond mean…
