Description
Measurements can qualitatively alter correlations and entanglement emerging in gapless quantum matter. Using the Ising spin chain as case study, I will study the impact of measurements in an explicit protocol involving uncorrelated ancillae entangled with the critical chain and subsequently measured projectively. By varying the measurement basis, we induce renormalization‐group flows between distinct conformally invariant boundary conditions. I will also investigate the effects of measurements on the tricritical Ising model, uncovering how they can trigger a non-trivial flow to different boundary conditions. These results point to a new way of engineering and probing boundary criticality via local measurements.
