Postselection-free ballistic-diffusive transition in monitored spin chains
K. G. S. H. Gunawardana, Ali G. Moghaddam, Teemu Ojanen
We study spin and entanglement dynamics in spin-1/2 XXZ chains under periodic monitoring and show that this system exhibits two measurement-induced phase transitions: a steady-stat…

Measurement Induced Asymmetric Entanglement in a Deconfined Quantum Critical Ground State
K. G. S. H. Gunawardana
In this work, we numerically study the effect of weak measurement on deconfined quantum critical point(DQCP). Particularly, we consider the ground state of an one-dimensional spin…
