Measurement of the separation between atoms beyond diffraction limit

Jun-Tao Chang, Joerg Evers, Marlan O. Scully +1

Precision measurement of small separations between two atoms or molecules has been of interest since the early days of science. Here, we discuss a scheme which yields spatial infor…

Quantum correlations of an atomic ensemble via a classical bath

M. Macovei, J. Evers, C. H. Keitel

Somewhat surprisingly, quantum features can be extracted from a classical bath. For this, we discuss a sample of three-level atoms in ladder configuration interacting only via the…

Rapid refractive index enhancements via laser-mediated collectivity

Mihai Macovei, Christoph H Keitel

The collective interaction via the environmental vacuum is investigated for a mixture of two deviating multi-atom ensembles in a moderately intense laser field. Due to the numerous…

Analytical Approach to Wave Packet Dynamics of Laser-Driven Particles beyond the Dipole Approximation

M. Verschl, C. H. Keitel

An analytical approach to quantum mechanical wave packet dynamics of laser-driven particles is presented. The time-dependent Schroedinger equation is solved for an electron exposed…

Phase-dependent interference mechanisms in a three-level Lambda system driven by a quantized laser field

Joerg Evers

The dynamics of an atomic few-level system can depend on the phase of driving fields coupled to the atom if certain conditions are satisfied. This is of particular interest to cont…

Strong-field approximation for intense-laser atom processes: the choice of gauge

D. Bauer, D. B. Milosevic, W. Becker

The strong-field approximation can be and has been applied in both length gauge and velocity gauge with quantitatively conflicting answers. For ionization of negative ions with a g…

Calculation of Hydrogenic Bethe Logarithms for Rydberg States

Ulrich D. Jentschura, Peter J. Mohr

We describe the calculation of hydrogenic (one-loop) Bethe logarithms for all states with principal quantum numbers n <= 200. While, in principle, the calculation of the Bethe loga…

Attosecond double-slit experiment

F. Lindner, M. G. Schaetzel, H. Walther +7

A new scheme for a double-slit experiment in the time domain is presented. Phase-stabilized few-cycle laser pulses open one to two windows (``slits'') of attosecond duration for ph…

Radiative Corrections to Multi-Level Mollow-Type Spectra

Ulrich D. Jentschura, Joerg Evers, Christoph H. Keitel

This paper is concerned with two rather basic phenomena: the incoherent fluorescence spectrum of an atom driven by an intense laser field and the coupling of the atom to the (empty…
