Topology and Spectrum in Measurement-Induced Phase Transitions
Hisanori Oshima, Ken Mochizuki, Ryusuke Hamazaki +1
Competition among repetitive measurements of noncommuting observables and unitary dynamics can give rise to a wide variety of entanglement phases. Here, we propose a general framew…
Threefold Way for Typical Entanglement
Haruki Yagi, Ken Mochizuki, Zongping Gong
A typical quantum state with no symmetry can be realized by letting a random unitary act on a fixed state, and the subsystem entanglement spectrum follows the Laguerre unitary ense…
Measurement-Induced Spectral Transition
Ken Mochizuki, Ryusuke Hamazaki
We show that noisy quantum dynamics exposed to weak measurements exhibit a spectral transition between gapless and gapped phases. To this end, we employ the Lyapunov spectrum obtai…
Multifractality in monitored single-particle dynamics
Kohei Yajima, Hisanori Oshima, Ken Mochizuki +1
We study multifractal properties in time evolution of a single particle subject to repeated measurements. For quantum systems, we consider circuit models consisting of local unitar…
