Now, angular momentum has been observed flowing coherently between distinct lattice vibrational modes, revealing a hidden propagation of rotational features inside the crystal.Tue, 12 May 2026 00:00:00 +0000https://www.nature.com/articles/s41567-026-03248-wLaser mode braiding on a chiphttps://www.nature.com/articles/s41567-026-03288-2reply.relevance=6 reply.impact=5 Highest h-index author on this paper: Wenbo Mao (h-index 0) Institution (first & last author): Unknown Non-Hermitian systems support non-trivial topological effects, yet eigenvalue braiding remains difficult to control and observe. Now, active tuning of laser modes enables programmable and directly observable braiding on an integrated photonic chip.Tue, 12 May 2026 00:00:00 +0000https://www.nature.com/articles/s41567-026-03288-2Observation of angular momentum transfer among crystal lattice modeshttps://www.nature.com/articles/s41567-026-03274-8reply.relevance=7 reply.impact=6 Highest h-index author on this paper: J. Urban (h-index 38) Institution (first & last author): Unknown How angular momentum is exchanged and conserved among lattice modes has been difficult to measure experimentally, but has now been observed via a coherent three-phonon scattering process in a topological insulator.Tue, 12 May 2026 00:00:00 +0000https://www.nature.com/articles/s41567-026-03274-8Correlated insulator in the kagome flat band of a two-dimensional electrostatic crystalhttps://www.nature.com/articles/s41567-026-03291-7reply.relevance=8 reply.impact=7 Highest h-index author on this paper: O. P. Sushkov (h-index 46) That author's affiliation: UNSW Sydney First author institution: UNSW Sydney Last author institution: University of Canberra A tunable artificial crystal in a shallow GaAs quantum well is shown to enable interaction-driven insulating behaviour. Electrostatic control tunes the band structure from graphene-like to kagome-like bands.Mon, 11 May 2026 00:00:00 +0000https://www.nature.com/articles/s41567-026-03291-7
