Localization, fractality, and ergodicity in a monitored qubit
Paul Pöpperl, Igor V. Gornyi, David B. Saakian +1
We study the statistical properties of a single two-level system (qubit) subject to repetitive ancilla-based measurements. This setup is a fundamental minimal model for exploring t…

Theory of free fermions under random projective measurements
Igor Poboiko, Paul Pöpperl, Igor V. Gornyi +1
We develop an analytical approach to the study of one-dimensional free fermions subject to random projective measurements of local site occupation numbers, based on the Keldysh pat…
