• Editor’s summaryTransitions between phases with unrelated symmetries are expected to be discontinuous. Nearly two decades ago, a different, continuous kind of transition between such phases was proposed under the name deconfined quantum critical point (DQCP). However, observing the DQCP experimentally has proven to be extremely challenging. Cui et al. used nuclear magnetic resonance to study the magnetic field–driven transitions of the layered material SrCu2(BO3)2 at various pressures. At high pressures, the experimental results combined with numerical calculations pointed to the existence of a nearby DQCP. —Jelena Stajic
