Beyond two-stage models for lung carcinogenesis in the Mayak workers: Implications for Plutonium risk

Sascha Zöllner, Mikhail E. Sokolnikov, Markus Eidemüller

Mechanistic multi-stage models are used to analyze lung-cancer mortality after Plutonium exposure in the Mayak-workers cohort, with follow-up until 2008. Besides the established tw…

Bosonic and fermionic dipoles on a ring

Sascha Zöllner, G. M. Bruun, C. J. Pethick +1

We show that dipolar bosons and fermions confined in a quasi-one-dimensional ring trap exhibit a rich variety of states because their interaction is inhomogeneous. For purely repul…

Polarons and Molecules in a Two-Dimensional Fermi Gas

Sascha Zöllner, G. M. Bruun, C. J. Pethick

We study an impurity atom in a two-dimensional Fermi gas using variational wave functions for (i) an impurity dressed by particle-hole excitations (polaron) and (ii) a dimer consis…

Binding between two-component bosons in one dimension

Emmerich Tempfli, Sascha Zöllner, Peter Schmelcher

We investigate the ground state of one-dimensional few-atom Bose-Bose mixtures under harmonic confinement throughout the crossover from weak to strong inter-species attraction. The…

The granularity of weakly occupied bosonic fields beyond the local density approximation

M. Eckart, R. Walser, W. P. Schleich +2

We examine ground state correlations for repulsive, quasi one-dimensional bosons in a harmonic trap. In particular, we focus on the few particle limit N=2,3,4,..., where exact nume…

Excitations of attractive 1-D bosons: Binding vs. fermionization

Emmerich Tempfli, Sascha Zöllner, Peter Schmelcher

The stationary states of few bosons in a one-dimensional harmonic trap are investigated throughout the crossover from weak to strongly attractive interactions. For sufficient attra…
