  • Quantum computers may help to solve classically intractable problems, such as simulating non-equilibrium dissipative quantum systems. The critical dynamics of a dissipative quantum model has now been probed on a trapped-ion quantum computer.

  • The combination of disorder and strong interactions makes it hard to understand the nature of doped silicon’s insulating phase. State-of-the-art spectroscopy measurements show marginal electronic behaviour reminiscent of what is seen in the cuprates.

  • Optical lattices, generated by interfering laser beams, provide a platform for observing condensed-matter phenomena in ultracold-atom systems. By extending the lattice idea to a multimode cavity, it should be possible to observe even more complex effects, such as frustration, crystallization, glass phases and supersolidity.

  • Fluctuating hydrodynamics posits that thermalization in non-equilibrium systems depends on equilibrium transport coefficients. This hypothesis is now tested by exploring the emergence of fluctuations in non-equilibrium dynamics of ultracold atoms.

  • Nearly integrable one-dimensional Bose gases are used to explain the behaviour of many-body quantum systems immediately after a rapid, high-energy quench, which shows two distinct timescales, one for hydrodynamization and the other for local prethermalization.

  • An optical lattice for trapping a Bose–Einstein condensate reported here includes photon-mediated atom–atom interactions that replicate acoustic modes in real crystals.

  • Quasiperiodic systems share features with disordered models but their underlying determinism give them distinct behaviour. Here the authors study the critical behaviour of quasiperiodic spin models and show that the renormalization group fixed points have couplings given by self-similar discrete sequences.

  • Nitrogen vacancy centre quantum sensors are quantitative, non-invasive and physically robust probes of condensed matter systems that offer nanoscale resolution across a wide range of temperatures. This Technical Review discusses the connections between NV measurements and important physical characteristics in condensed matter.

  • The Kondo effect is a prototypical strongly correlated phenomenon, in which a strong, localized repulsion gives rise to a many body resonance that controls the low-energy physics of a metal. Here, the authors show that the same effect can be induced by purely dissipative means through localized two body losses, which provides a nontrivial–and experimentally relevant– application of nonlinear dissipation.
