Random Acts of Science

Everyone working on quantum information theory has his or her favourite interpretation of quantum mechanics. Those interested in the history and philosophy of quantum mechanics will find an interesting presentation of philosophical controversies concerning quantum mechanics in the recent book "Quantum" by Manjit Kumar. Graham Farmelo, the author of “The Strangest Man,” a biography of Paul Dirac, in his review written for New York Times writes: ''[..] Manjit Kumar cites a poll about the interpretation of quantum mechanics, taken among physicists at a conference in 1999.

Quantum guessing games

David Voss at APS Physics writes: ''Nonlocality—the entanglement of one object with another at a distance—is a powerful way to achieve quantum information processing. However, quantum mechanics is tethered by a “no-signaling” principle, that is, these correlations cannot be used to transmit information arbitrarily quickly from one point to another.

Noise correlations of one-dimensional Bose mixtures in optical lattices

ArXiv identifier:

1002.4918

Speakers:

Anzi Hu and Ludwig Mathey

Authors:

Anzi Hu, L. Mathey, Carl J. Williams, Charles W. Clark

We study the noise correlations of one-dimensional binary Bose mixtures, as a probe of their quantum phases. In previous work, we found a rich structure of many-body phases in such mixtures, such as paired and counterflow superfluidity. Here we investigate the signature of these phases in the noise correlations of the atomic cloud after time-of-flight expansion, using both Luttinger liquid theory and the time-evolving block decimation (TEBD) method. We find that paired and counterflow superfluidity exhibit distinctive features in the noise spectra.

MUARC Summer school on Advanced Techniques in Atomic Physics

The school is intended to enable advanced graduate students or early post-docs to target the next step in their career. The idea is to provide a first step into new scientific topics and the associated techniques at the interface of Cold Atoms and Quantum Optics. Each scientific topic will be given at least 4 hours, of which 50% are dedicated to the techniques and real-world challenges. In addition we will offer perspectives in funding and careers beyond science in a set of hour-long lectures.
