Time complexity of a monitored quantum search with resetting
Emma C. King, Sayan Roy, Francesco Mattiotti +3
Searching a database is a central task in computer science and is paradigmatic of transport and optimization problems in physics. For an unstructured search, Grover's algorithm pre…
Absence of true localization in many-body localized phases
Maximilian Kiefer-Emmanouilidis, Razmik Unanyan, Michael Fleischhauer +1
We have recently shown that the logarithmic growth of the entanglement entropy following a quantum quench in a many-body localized (MBL) phase is accompanied by a slow growth of th…
Evidence for unbounded growth of the number entropy in many-body localized phases
Maximilian Kiefer-Emmanouilidis, Razmik Unanyan, Michael Fleischhauer +1
We investigate the number entropy ---which characterizes particle-number fluctuations between subsystems---following a quench in one-dimensional interacting many-body systems…
Bounds on the entanglement entropy by the number entropy in non-interacting fermionic systems
Maximilian Kiefer-Emmanouilidis, Razmik Unanyan, Jesko Sirker +1
Entanglement in a pure state of a many-body system can be characterized by the Rényi entropies of the reduced density matrix of a subsystem.…
Current reversals and metastable states in the infinite Bose-Hubbard chain with local particle loss
M. Kiefer-Emmanouilidis, J. Sirker
We present an algorithm which combines the quantum trajectory approach to open quantum systems with a density-matrix renormalization group scheme for infinite one-dimensional latti…
