Quantum walks of correlated photon pairs in two-dimensional waveguide arrays
Konstantinos Poulios, Robert Keil, Daniel Fry +9
We demonstrate quantum walks of correlated photons in a 2D network of directly laser written waveguides coupled in a 'swiss cross' arrangement. The correlated detection events show…
Relativistic calculations of the U91+(1s)-U92+ collision using the finite basis set of cubic Hermite splines on a lattice in coordinate space
G. B. Deyneka, I. A. Maltsev, I. I. Tupitsyn +5
A new method for solving the time-dependent two-center Dirac equation is developed. The approach is based on the using of the finite basis of cubic Hermite splines on a three-dimen…
Dynamic localization in Glauber-Fock lattices
S. Longhi, A. Szameit
Glauber-Fock lattices refer to a special class of semi-infinite tight-binding lattices with inhomogeneous hopping rates which are found in certain simple solid-state, quantum optic…
Vacuum-assisted generation and control of atomic coherences at x-ray energies
Kilian P. Heeg, Hans-Christian Wille, Kai Schlage +9
The control of light-matter interaction at the quantum level usually requires coherent laser fields. But already an exchange of virtual photons with the electromagnetic vacuum fiel…
Bessel beams of two-level atoms driven by a linearly polarized laser field
Armen G. Hayrapetyan, Oliver Matula, Andrey Surzhykov +1
We study Bessel beams of two-level atoms that are driven by a linearly polarized laser field. Starting from the Schroedinger equation, we determine the states of two-level atoms in…
