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…
Comment on "Resonance-induced growth of number entropy in strongly disordered systems"
Maximilian Kiefer-Emmanouilidis, Razmik Unanyan, Michael Fleischhauer +1
We comment on the recent paper by Ghosh and Žnidarič (Phys. Rev. B 105, 144203 (2022)) which studies the growth of the number entropy in the Heisenberg model with random magn…
Quantum spin liquids of Rydberg excitations in a honeycomb lattice induced by density-dependent Peierls phases
Simon Ohler, Maximilian Kiefer-Emmanouilidis, Michael Fleischhauer
We show that the nonlinear transport of bosonic excitations in a two-dimensional honeycomb lattice of spin-orbit coupled Rydberg atoms gives rise to disordered quantum phases which…
Self-generated quantum gauge fields in arrays of Rydberg atoms
Simon Ohler, Maximilian Kiefer-Emmanouilidis, Antoine Browaeys +2
As shown in recent experiments [V. Lienhard et al., Phys. Rev. X 10, 021031 (2020)], spin-orbit coupling in systems of Rydberg atoms can give rise to density-dependent Peierls Phas…
Particle fluctuations and the failure of simple effective models for many-body localized phases
Maximilian Kiefer-Emmanouilidis, Razmik Unanyan, Michael Fleischhauer +1
We investigate and compare the particle number fluctuations in the putative many-body localized (MBL) phase of a spinless fermion model with potential disorder and nearest-neighbor…
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.…
Finite-temperature topological invariant for interacting systems
Razmik Unanyan, Maximilian Kiefer-Emmanouilidis, Michael Fleischhauer
We generalize the Ensemble Geometric Phase (EGP), recently introduced to classify the topology of density matrices, to finite-temperature states of interacting systems in one spati…
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…
