Time delays in anisotropic systems
Ulf Saalmann, Jan M. Rost
Scattering properties and time delays for general (non-symmetric) potentials in terms of the respective S-matrices are discussed paradigmatically in one dimension and in comparison…
Laser-assisted Fano resonance: attosecond quantum control and dynamical imaging
Meng Han, Hao Liang, Jia-bao Ji +4
A Fano resonance arises from the pathway interference between discrete and continuum states, playing a fundamental role in many branches of physics, chemistry and material science.…
Fano Resonances in Quantum Transport with Vibrations
Ajith Ramachandran, Michael Genkin, Auditya Sharma +3
Quantum mechanical scattering involving continuum states coupled to a scatterer with a discrete spectrum gives rise to Fano resonances. Here we consider scatterers that possess int…
Dressed ion-pair states of an ultralong-range Rydberg molecule
P. Giannakeas, Matthew T. Eiles, F. Robicheaux +1
We predict the existence of a universal class of ultralong-range Rydberg molecular states whose vibrational spectra form trimmed Rydberg series. A dressed ion-pair model captures t…
Cavity-free quantum optomechanical cooling by atom-modulated radiation
Hoi-Kwan Lau, Alexander Eisfeld, Jan-Michael Rost
We theoretically study the radiation-induced interaction between the mechanical motion of an oscillating mirror and a remotely trapped atomic cloud. When illuminated by continuous-…
Coupling of a nano mechanical oscillator and an atomic three-level medium
A. Sanz-Mora, A. Eisfeld, S. Wüster +1
We theoretically investigate the coupling of an ultracold three-level atomic gas and a nano-mechanical mirror via classical electromagnetic radiation. The radiation pressure on the…
Atomic and Molecular Systems Driven by Intense Chaotic Light
Kamal P Singh, Jan M Rost
We investigate dynamics of atomic and molecular systems exposed to intense, shaped chaotic fields and a weak femtosecond laser pulse theoretically. As a prototype example, the phot…
Anomalous quantum reflection as a quasi-dynamical damping effect
Alexander Jurisch, Jan-Michael Rost
We develop a quasi-analytical theory for the quantum reflection amplitude of Bose-Einstein condensates. We derive and calculate the decay-width of a Bose-Einstein condensate. A gen…
Trapping cold Atoms by Quantum Reflection
Alexander Jurisch, Jan-Michael Rost
We examine the properties of a quantum reflection trap when particle-interaction is included. We explore the influence of the particle-interaction on the trapping for different reg…
Dissociation and ionization of small molecules steered by external noise
Anatole Kenfack, Jan M. Rost, Frank Grossmann
We show that ionization and dissociation can be influenced separately in a molecule with appropriate external noise. Specifically we investigate the hydrogen molecular ion under a…
Molecular effects in the ionization of N, O and F by intense laser fields
Daniel Dundas, Jan M. Rost
In this paper we study the response in time of N, O and F to laser pulses having a wavelength of 390nm. We find single ionization suppression in O and its absence i…
Atomic scattering from Bose-Einstein condensates
Ivo Haering, Jan M Rost
Elastic scattering probes directly the interaction potential. For weakly interacting condensates this potential is given by the condensate density. We investigate how the different…
Time Dependence in Quantum Mechanics
John S Briggs, Jan M Rost
It is shown that the time-dependent equations (Schrödinger and Dirac) for a quantum system can be always derived from the time-independent equation for the larger object of the sys…
