Quantum Speed Limit and Optimal Control of Many-Boson Dynamics
Ioannis Brouzos, Alexej I. Streltsov, Antonio Negretti +4
We extend the concept of quantum speed limit -- the minimal time needed to perform a driven evolution -- to complex interacting many-body systems. We investigate a prototypical man…
Invariant currents and scattering off locally symmetric potential landscapes
P. A. Kalozoumis, C. Morfonios, F. K. Diakonos +1
We study the effect of discrete symmetry breaking in inhomogeneous scattering media within the framework of generic wave propagation. Our focus is on one-dimensional scattering pot…
Symmetries and transport in site-dependently driven quantum lattices
Thomas Wulf, Christoph Petri, Benno Liebchen +1
We explore the quantum dynamics of particles in a spatiotemporally driven lattice. A powerful numerical scheme is developed, which provides us with the Floquet modes and thus enabl…
Invariants of broken discrete symmetries
P. Kalozoumis, C. Morfonios, F. K. Diakonos +1
The parity and Bloch theorems are generalized to the case of broken global symmetry. Local inversion or translation symmetries are shown to yield invariant currents that characteri…
Interferometry with non-classical motional states of a Bose-Einstein condensate
Sandrine van Frank, Antonio Negretti, Tarik Berrada +6
We demonstrate a two-pulse Ramsey-type interferometer for non-classical motional states of a Bose-Einstein condensate in an anharmonic trap. The control pulses used to manipulate t…
Strongly driven quantum pendulum of the OCS molecule
S. Trippel, T. Mullins, N. L. M. Müller +5
We demonstrate and analyze a strongly driven quantum pendulum in the angular motion of stateselected and laser aligned OCS molecules. Raman-couplings during the rising edge of a 50…
