Fractionally Quantized Recurrence Detection Times in Monitored Quantum Many-Body Systems (opens in new tab)

arXiv:2401.09810v2 Announce Type: replace-cross Abstract: Recurrence time quantifies the duration required for a physical system to return to its initial state, playing a pivotal role in understanding the predictability of complex systems. In quantum systems with subspace measurements, recurrence times are governed by Anandan-Aharonov phases, yielding fractionally quantized recurrence times. However, the fractional quantization phenomenon in interacting quantum systems remains unexplored. Her...
