Sep 10 - Darfield earthquake damages Canterbury "Information so far suggests that the fault is pre-existing, and a patch has been reactivated during the Darfield earthquake. Large up to km long normal faults with the same strike direction are numerous on the Chatham Rise, out to sea east of Banks Peninsula.

Christmas Party last modified on December 22 Antiferromagnetic Heisenberg spin chains last modified on November 20 Without the need Modified thesis an external periodic potential, these spin chains are stabilized by strong repuslive interactions and a one-dimensiional trapping geometry.
This work constitutes the first observation of quantum magnetism with ultracold fermions that exceeds nearest-neighbor correlations.
Ground-state systems of up to four atoms shown in green and blue are prepared in a strongly-elongated optical dipole trap red in which they can move in one dimension only. When the atoms do not interact, they can move Modified thesis in the trap top picture and they have no discernible order.
When repulsive interactions between the atoms become strong bottom picturethey can not pass each other anymore and independently arrange themselves in an antiferromagnetic spin chain.
Group retreat at Trifels last modified on August 3 We recently held a group retreat in Annweiler near the famous castle Trifels in the Pfalz. Experimental methods for wood-cutting and campfire-making were established.

We saw the onset of power-law behavior at low temperatures. More interestingly, we measured the scaling exponents and observed that the inhomogeneity of the system leads to a change of the universal critical exponents predicted by the BKT Theory.
The results of this work have been recently published in Physical Review Lettersalso available at arXiv: The paper was also selected for an Editors' Suggestion! An artist's impression of the complex phase of a two-dimensional superfluid which is described by the Berezinskii-Kosterlitz-Thouless BKT theory.
The two most prominent features of BKT theory are spatial phase fluctuations and bound pairs of topological vortices. The phase fluctuations have a peculiar spectrum which leads to algebraically decaying correlations, which are measured in this work for a fermionic superlfuid.
Above a critical temperature the vortex pairs unbind and the individual vortices disorder the system such that superfluidity is lost.Other Cultures Collections of resources and information, mainly external to Ethnomed, on specific groups of refugee and immigrants.
Involuntary Committment and Recovery: An Innovative Mental Health Peer Support Program (Doctoral Thesis) by Mary Ellen Copeland, Ph.D. Publish Date: January The chosen TeX Gyre Heros is the font not only without serifs, but also has heavier weight compared to Charter — this results in a good visual separation of the headings from the rest text making TeX Gyre Heros a good companion for the body text typeset with Charter.
