The project is aimed at the creation and manipulation of atomic density patterns by contact-free self-assembly due to optomechanical forces. We are looking at large patches (samples size of some millimetres) of laser cooled matter (around 100 µK), which will be structured on scales of wavelengths to hundreds of micrometres. The spatial structure is not imposed externally but evolves spontaneously from an instability of the homogeneous atomic cloud in interaction with a homogeneous light field.

The Department of Applied Mathematics and Theoretical Physics (http://www.damtp.cam.ac.uk/) invites applications for a Post-doctoral Research Associate or Senior Research Associate to commence on 1st October 2013 (or another date by agreement).

The goal of this Workshop is to bring together researchers who study the random walk, quantum random walk, and the open quantum random walk in the sense of applied computational mathematics. The organizer strongly encourages the young researchers as well as the leading figures in these areas to actively join this workshop and make a presentation. We strongly encourage submissions that allow the interaction between the random walk, quantum random walk, and the open quantum random walk, or showcase the interdisciplinary nature of stochastic processes.

Applications are invited from outstanding candidates for the above post. The successful candidate will be expected to contribute strongly to maintaining and enhancing the School’s high standards in teaching and research.

Centrum Wiskunde & Informatica (CWI) has a vacancy in the Algorithms and Complexity research group for a postdoctoral researcher.

This position involves research into the computer-science aspects of quantum computing and quantum information theory, in close cooperation with Prof. Ronald de Wolf.

Title: What is the origin of complex probability amplitudes?
Abstract: I begin this presentation with an attempt to explain the origin of probability amplitudes in quantum theory, but the explanation makes sense only if those amplitudes are real. This result provides motivation for studying the real-vector-space variant of quantum theory. I show how a particular model within real-vector-space quantum theory can produce the appearance of complex probability amplitudes.
