Ultracold atoms point toward magnetic behavior
2017/10/25
The researchers found that applying a strong magnetic field to these ultracold atoms caused them to line up in an alternating pattern and lean away from each other. The behavior, which researchers cal...

Simulating superconducting materials ultracold atoms
2015/3/4
Using ultracold atoms as a stand-in for electrons, a Rice University-based team of physicists has simulated superconducting materials and made headway on a problem that’s vexed physicists for nearly t...

2011/9/9
We investigate the resonantly enhanced tunneling dynamics of ultracold bosons loaded on a tilted 1-D optical lattice, which can be used to simulate a chain of Ising spins and associated quantum phase ...
Ultracold Atoms as a Target: Absolute Scattering Cross-Section Measurements
Ultracold Atoms Target Scattering Cross-Section Measurements
2010/11/12
We report on a new experimental platform for the measurement of absolute scattering cross-sections. The target atoms are trapped in an optical dipole trap and are exposed to an incident particle beam...
We report a technique that uses clouds of ultracold atoms as sensitive, tunable, and non-invasive probes for microwave eld imaging with micrometer spatial resolution. The microwave magnetic eld comp...

2010/10/21
We show that gauge transformations can be simulated on systems of ultracold atoms. We discuss observables that are invariant under these gauge transformations and compute them using a tensor network a...
Physicists in Italy have shown how to transfer entropy from one ultracold gas to another using a laser beam. They say that the resulting low-entropy gas could be the ideal system for investigating qua...
