Assuming dark matter exists, its interactions with ordinary matter are so subtle that even the most sensitive instruments cannot detect them. In a new study, Northwestern University physicists now ...

A new concept for energy transfer between gravitational waves and light. When massive cosmic objects such as black holes merge or neutron stars crash into one another, they can produce gravitational ...

Perhaps one of the most famous experiments in physics has been giving us the wrong message all these years. For nearly two ...

When two black holes merge or two neutron stars collide, gravitational waves can be generated. They spread at the speed of ...

Physicists have created a quantum interferometer on an atom chip. This device can be used to explore the fundamentals of quantum theory by studying the interference pattern between two beams of atoms.

Prof. Ralf Schützhold at Helmholtz-Zentrum Dresden-Rossendorf (HZDR) has devised an experiment that allows for not only the ...

Physicists at the National Institute of Standards and Technology (NIST) have demonstrated a novel way of making atoms interfere with each other, recreating a famous experiment originally done with ...

One of the most important experiments of quantum physics gets a makeover: When neutrons are fired at a crystal, they can be made to travel along two paths at the same time. Until now, this was only ...

Interferometers are research instruments that are utilized in many disciplines of science and technology. Interferometers are so-called because they function by combining multiple sources of light to ...
