Zhang, Lei, Gilbert, Matthew, Pedersen, Jesper, Shumway, John
We explore exchange coupling of a pair of spins in a double dot and in an optical lattice. Our algorithm uses the frequency of exchanges in a bosonic path integral, evaluated with Monte Carlo. This...
Optical properties of graphene antidot lattices (2008)
Pedersen, Thomas G., Flindt, Christian, Pedersen, Jesper, Jauho, Antti-Pekka, Mortensen, Niels Asger, Pedersen, Kjeld
Undoped graphene is semi-metallic and thus not suitable for many electronic and optoelectronic applications requiring gapped semiconductor materials. However, a periodic array of holes (antidot...
Graphene Antidot Lattices - Designed Defects and Spin Qubits (2008)
Pedersen, Thomas G., Flindt, Christian, Pedersen, Jesper, Mortensen, Niels Asger, Jauho, Antti-Pekka, Pedersen, Kjeld
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. We point out that...
Pedersen, Jesper, Xiao, Sanshui, Mortensen, Niels Asger
Slow-light enhanced absorption in liquid-infiltrated photonic crystals has recently been proposed as a route to compensate for the reduced optical path in typical lab-on-a-chip systems for...
Designed defects in 2D antidot lattices for quantum information processing (2008)
Pedersen, Jesper, Flindt, Christian, Mortensen, Niels Asger, Jauho, Antti-Pekka
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 a semiconductor...
Spin qubits in antidot lattices (2008)
Pedersen, Jesper, Flindt, Christian, Mortensen, Niels Asger, Jauho, Antti-Pekka
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 information processing...
Enhanced circular dichroism via slow-light in dispersive structured media (2007)
Pedersen, Jesper, Mortensen, Niels Asger
Circular dichroism (CD) is in widespread use as a means of determining enantiomeric excess. We show how slow-light phenomena in dispersive structured media allow for a reduction in the required...
Mortensen, Niels Asger, Xiao, Sanshui, Pedersen, Jesper
Optical techniques are finding widespread use in analytical chemistry for chemical and bio-chemical analysis. During the past decade, there has been an increasing emphasis on miniaturization of...
Failure of standard approximations of the exchange coupling in nanostructures (2007)
Pedersen, Jesper, Flindt, Christian, Mortensen, Niels Asger, Jauho, Antti-Pekka
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 exchange coupling...
