Measurement of the topological Chern number by continuous probing of a qubit subject to a slowly varying Hamiltonian
Peng Xu, Alexander Holm Kiilerich, Ralf Blattmann +3
We analyze a measurement scheme that allows determination of the Berry curvature and the topological Chern number of a Hamiltonian with parameters exploring a two-dimensional close…
Macroscopic realism of quantum work fluctuations
Ralf Blattmann, Klaus Mølmer
We study the fluctuations of the work performed on a driven quantum system, defined as the difference between subsequent measurements of energy eigenvalues. These work fluctuations…
Conditioned quantum motion of an atom in a continuously monitored 1D lattice
Ralf Blattmann, Klaus Mølmer
We consider a quantum particle on a one dimensional lattice subject to weak local measurements and study its stochastic dynamics conditioned on the measurement outcomes. Depending…
Landau-Zener interference at bichromatic driving
F. Forster, M. Mühlbacher, R. Blattmann +4
We investigate experimentally and theoretically the interference at avoided crossings which are repeatedly traversed as a consequence of an applied ac field. Our model system is a…
