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…
Measurements on an Anderson Chain
Paul Pöpperl, Igor V. Gornyi, Yuval Gefen
We study the dynamics of a monitored single particle in a one-dimensional, Anderson-localized system. The time evolution is governed by Hamiltonian dynamics for fixed time interval…
Memory effects in the density-wave imbalance in delocalized disordered systems
Paul Pöpperl, Igor V. Gornyi, Alexander D. Mirlin
Dynamics of the imbalance in occupations on even and odd sites of a lattice serves as one of the key characteristics for identification of the many-body localization transition. In…
