The radius of the proton, generally assumed to be a well measured and understood  quantity has recently come under scrutiny due to highly precise, yet conflicting, experimental results. These new results have generated a host of interpretations, none of which are completely satisfactory. [mehr]

Large spin systems can exhibit unconventional types of magnetic ordering different from the ferromagnetic or N\'eel-like antiferromagnetic order commonly found in spin 1/2 systems. [mehr]

The availability of waveform-controlled, intense, few cycle laser fields has radically expanded the ability of scientists to peer into the dynamics of atoms and solids on few-femtosecond or even attosecond time scales. This research in the field of attosecond science has hinted at the potential for new discoveries that may be unlocked by new developments in laser science to confine more and more energy into smaller and smaller packages to be precisely delieved to the systems under study.

It was long considered a practical impossibility to extend the methods of laser cooling and trapping to diatomic molecules. [mehr]

Quantum correlations are strongly enhanced near quantum critical points, which opens attractive prospects for applications such as quantum-enhanced metrology. [mehr]
