  • The physics of one-dimensional many-body systems is rich but still insufficiently understood. An ultracold atom experiment investigates the behaviour of one-dimensional strongly correlated fermions with a tunable number of spin components.

  • Researchers provide experimental evidence of intrinsic linewidths approaching the quantum limit in a GaAs/AlGaAs quantum cascade laser emitting at 2.5 THz. Despite the expected dominant broadening effect induced by thermal photons, the measured intrinsic linewidth is 90 Hz — even narrower than that of a semiconductor laser working at significantly shorter wavelengths.

  • Mutually repulsive atoms placed at periodic intervals in a ‘crystal of light’ can, counterintuitively, be forced into stable couplings. That theoretical prediction has just seen experimental confirmation.

  • The elusive effects of quantum gravity could be betrayed by subtle deviations from standard quantum mechanics. An experiment using the gravitational wave bar detector AURIGA explores the limits of quantum gravity-induced modifications in the ground state of a mechanical oscillator cooled to the sub-millikelvin regime.
