‘Spooky action at a distance’ could create a nearly perfect clock

Physicists imagine a day when they will be able to design a clock that’s so precise, it will be used to detect subtle disturbances in space-time or to find the elusive dark matter that tugs on everything yet emits no light. The ticking of this clock will be almost perfect. That dream may not be far off:...

New type of atomic clock keeps time even more precisely

Atomic clocks are the most precise timekeepers in the world. These exquisite instruments use lasers to measure the vibrations of atoms, which oscillate at a constant frequency, like many microscopic pendulums swinging in sync. The best atomic clocks in the world keep time with such precision that, if they had been running since the beginning...

Researchers observe what could be the first hints of dark bosons

Extremely light and weakly interacting particles may play a crucial role in cosmology and in the ongoing search for dark matter. Unfortunately, however, these particles have so far proved very difficult to detect using existing high-energy colliders. Researchers worldwide have thus been trying to develop alternative technologies and methods that could enable the detection of...

New phase transition in the standard model of quantum optics

Proposed in 1954 by Robert H. Dicke, the Dicke `spin-boson’ model is among the most successful paradigms to describe the interaction of light and matter. Modeling the coupling of an ensemble of spins or atoms to a harmonic oscillator, it is thus sometimes referred to as the “standard model of quantum optics.” As discovered in...

A Polariton-Stabilized Spin Clock

Figure: A polaritonic-stabilized spin clock. The reference probe field at frequency ω with intensity I is is split into a local oscillator and probe. The latter is sent to the resonant system, which consists of NV centers in diamond with population relaxation rate γ coupled to a microwave cavity at rate g. Atomic clocks are...

Uncovering the mystery of the disappearing molecules

Ultracold molecules are a research frontier that builds upon the many successes of ultracold atoms in the study of quantum science. There has been much experimental effort dedicated to the realization of trapped gaseous samples of ultracold molecules. In fact, various research groups from around the world have successfully demonstrated methods to bring samples of...

Controlled Collisions of Exactly two Ultracold Molecules

One of the fundamental questions in the study of ultracold polar molecules is “what happens when two molecules collide at ultracold temperatures?” Knowing whether the molecules undergo chemical reactions, form long lived complexes, change internal state, or bounce off each other carries important implications which will guide future research directions. Our recent experiment explores this...
