Imaging the flat bands of magic-angle graphene reshaped by interactions

Cryogenic QTM All measurements in this work were performed in a cryogenic QTM system operating at a temperature of 4 K, as described previously45. For conductance measurement, voltage biases are applied using a custom-built digital-to-analogue converter array, capable of supplying both d.c. and a.c. signals with 1 μV resolution. Currents were measured using a FEMTO current amplifier,…

Relativistic plasmas open a route to extreme optical fields

RESEARCH BRIEFINGS 06 May 2026 By precisely shaping the leading edge of ultrafast high-power laser pulses, bright ‘harmonic’ radiation has been generated with great efficiency from plasma oscillating at almost the speed of light. This long-sought regime removes a key barrier to the production of extremely intense electromagnetic fields for applications such as compact particle…
