Such a transition separ ates phases characterized by\nhow much information an observer can learn f rom the measurement\noutcomes. We study SU(2)-symmetric monitored quantum circuits\, using\nexact numerics and a mapping onto an effective statistic al-mechanics\nmodel. Due to the symmetry's non-Abelian nature\, measuring qubit pairs\nallows for nontrivial entanglement scaling even in the\nmeasu rement-only limit. We find a transition between a volume-law\nentangled ph ase and a critical phase whose diffusive purification\ndynamics emerge fro m the non-Abelian symmetry. Additionally\, we\nidentify a “spin-sharpeni ng transition.” Across the transition\,\nthe rate at which measurements reveal information about the total spin\nquantum number changes parametric ally with system size.\n\nReference\n /10.1103/PhysRevB.108.054307\n[ 03/PhysRevB.108.054307]\n\nADD EVENT TO CALENDAR\n\nApple [https://www.add]  Google\n[ t/Pl18436547+google]  Office 365\n[ 547+office365]  Outlook\n[ ok]\n[]  Yahoo\n[]  \n DTSTAMP:20231204T133352Z END:VEVENT END:VCALENDAR
