Variational Perturbation Theory for Fokker-Planck Equation with Nonlinear Drift
Jens Dreger, Axel Pelster, Bodo Hamprecht
We develop a recursive method for perturbative solutions of the Fokker-Planck equation with nonlinear drift. The series expansion of the time-dependent probability density in terms…
Atomic Squeezing under Collective Emission
V. I. Yukalov, E. P. Yukalova
Atomic squeezing is studied for the case of large systems of radiating atoms, when collective effects are well developed. All temporal stages are analyzed, starting with the quantu…
Extrapolation of power series by self-similar factor and root approximants
V. I. Yukalov, S. Gluzman
The problem of extrapolating the series in powers of small variables to the region of large variables is addressed. Such a problem is typical of quantum theory and statistical phys…
Volume and lattice points of reflexive simplices
Benjamin Nill
We prove sharp upper bounds on the volume and the number of lattice points on edges of higher-dimensional reflexive simplices. These convex-geometric results are derived from new n…
Theory of charge sensing in quantum-dot structures
Richard Berkovits, Felix von Oppen, Yuval Gefen
Charge sensing in quantum-dot structures is studied by an exactly solvable reduced model and numerical density-matrix renormalization group methods. Charge sensing is characterized…
Controlled low-temperature molecular manipulation of sexiphenyl molecules on Ag(111) using scanning tunneling microscopy
Saw-Wai Hla, Kai-Felix Braun, Bernhard Wassermann +1
A novel scanning tunneling microscope manipulation scheme for a controlled molecular transport of weakly adsorbed molecules is demonstrated. Single sexiphenyl molecules adsorbed on…
