The race to build the first useful quantum computer is on and may revolutionize the world with brand new capabilities, from ...

A new method uses helium droplets combined with ultrashort laser pulses to trigger chemical reactions in a controlled way.

For the first time, a research team led by Markus Koch from the Institute of Experimental Physics at Graz University of Technology (TU Graz) has tracked in real time how individual atoms combine to ...

Collapsing energy bands to explore their geometric structure Date: June 1, 2016 Source: Max Planck Institute of Quantum Optics Summary: Researchers have devised a straightforward method to probe ...

Cold atoms are atoms that have been cooled to very low temperatures, below 1 mK, reducing their motion to a very low energy regime where quantum effects emerge.

Why is it that there are certain energies that an electron inside a material simply can not have? Like much of quantum physics, it's all because electrons are waves.

Cold atoms “The temperature scale as we know it starts at zero and goes up to infinity, but it doesn’t stop there,” says Ulrich Schneider of the Ludwig Maximilian University of Munich in ...

When the bottle is placed in hot water, the heat energy from the water makes the molecules in the gas inside the bottle move faster and spread further apart. As they spread further apart, they push ...

The cold-atom clouds contain neutral atoms, which – unlike ions – interact only very weakly with their surroundings. So even when an atom cloud has been cooled to 500 nK, the rest of the system – ...

Cold atoms are atoms that have been cooled to very low temperatures, below 1 mK, reducing their motion to a very low energy regime where quantum effects emerge. This makes them sensitive to some of ...

With cold atoms in an optical lattice, ... These are positions where two energy bands take on the same value, meaning that at these points electrons can easily jump from one energy band to another.

Our ensemble of cold 87 Rb atoms is loaded into an optical lattice of period a formed by retro-reflecting a light beam of wavelength λ o =2a ().In each period of such a dipole trap, the confined ...
