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]

The active laser cavity can be considerably more sensitive than a passive one to minute perturbations. The difference in sensitivity between passive and active resonator sensors is akin to forensic dissection as compared to vivisection. [mehr]

“We propose to use Quantum Hall edge channels in order to generate long-range entanglement between spatially separated spin qubits. Since the entanglement is actively stabilized by purely dissipative dynamics, our scheme is inherently robust against noise and imperfections.” [mehr]
