Quantum parameter-estimation of frequency and damping of a harmonic-oscillator
Patrick Binder, Daniel Braun
We determine the quantum Cramér-Rao bound for the precision with which the oscillator frequency and damping constant of a damped quantum harmonic oscillator in an arbitrary Gaussia…
Diversity of discrete breathers observed in a Josephson ladder
P. Binder, D. Abraimov, A. V. Ustinov
We generate and observe discrete rotobreathers in Josephson junction ladders with open boundaries. Rotobreathers are localized excitations that persist under the action of a spatia…
Experimental Critical Current Patterns in Josephson Junction Ladders
P. Binder, P. Caputo, M. V. Fistul +2
We present an experimental and theoretical study of the magnetic field dependence of the critical current of Josephson junction ladders. At variance with the well-known case of a o…
Observation of breathers in Josephson ladders
P. Binder, D. Abraimov, A. V. Ustinov +2
We report on the observation of spatially-localized excitations in a ladder of small Josephson junctions. The excitations are whirling states which persist under a spatially-homoge…
Inelastic quantum transport in superlattices: success and failure of the Boltzmann equation
A. Wacker, A. -P. Jauho, S. Rott +3
Electrical transport in semiconductor superlattices is studied within a fully self-consistent quantum transport model based on nonequilibrium Green functions, including phonon and…
