  • Semiconducting dipolar excitons — bound states of electrons and holes — in artificial moiré lattices constitute a promising condensed matter system to explore the phase diagram of strongly interacting bosonic particles.

  • The Kondo effect — the screening of an impurity spin by conduction electrons — is a fundamental many-body effect. However, recent experiments combined with simulations have caused a long-standing model system for the single-atom Kondo effect to fail.

  • It has been around fifty years since Kenneth Wilson’s work on the renormalization group. Nature Physics celebrates this anniversary with a collection of Comments on its development and applications.

  • The 2023 Nobel Prize in Physics has been awarded to Pierre Agostini, Ferenc Krausz and Anne L’Huillier “for experimental methods that generate attosecond pulses of light for the study of electron dynamics in matter”.

  • Although its measurement was considered an experimental nightmare for decades, the Stefan–Boltzmann constant was assigned an exact value in 2019. Massimiliano Malgieri and Pasquale Onorato explain what this story teaches us.

  • Kenneth Wilson worked on the renormalization group during the Cold War, when communication between scientists in the Soviet Union and in the West was restricted. Nevertheless, Soviet physicists had a strong influence on Wilson’s work.

  • Historically, most renormalization group studies have been performed for equilibrium systems. Here, I give a personal reflection on the unexpected outcome of studying non-equilibrium flocking using renormalization methods.

  • Supersymmetric quantum field theories have special properties that make them easier to study. This Comment discusses how the constraints that supersymmetry places on renormalization group flows have been used to study strongly coupled field theories.

  • The renormalization group evolved from ad hoc procedures to cope with divergences in perturbative calculations. This Comment summarizes efforts to develop a mathematically rigorous approach to renormalization group calculations.

  • Renormalization began as a tool to eliminate divergences in quantum electrodynamics, but it is now the basis of our understanding of physics at different energy scales. Here, I review its evolution with an eye towards physics beyond the Wilsonian paradigm.

  • Interactions between a localized magnetic moment and electrons in a metal can produce an emergent resonance that affects the metal’s properties. A realization of this Kondo effect in MoS2 provides an opportunity to study it in microscopic detail.

  • Permanent deformation in solids results from atoms not aligning with the external stress causing the deformation. Detecting such non-affine atomic rearrangements and connecting them to measurable mechanical effects is now shown to be feasible by means of high-energy X-ray diffraction.
