An O(N^2) Approximation for Hydrodynamic Interactions in Brownian Dynamics Simulations
Tihamer Geyer, Uwe Winter
In the Ermak-McCammon algorithm for Brownian Dynamics, the hydrodynamic interactions (HI) between N spherical particles are described by a 3N x 3N diffusion tensor. This tensor has…
Form follows function -- how PufX increases the efficiency of the light-harvesting complexes of Rhodobacter sphaeroides
Tihamer Geyer
Some species of purple bacteria as, e.g., Rhodobacter sphaeroides contain the protein PufX. Concurrently, the light harvesting complexes 1 (LH1) form dimers of open rings. In mutan…
A mapping approach to synchronization in the "Zajfman trap". II: the observed bunch
Tihamer Geyer, David J. Tannor
We extend a recently introduced mapping model, which explains the bunching phenomenon in an ion beam resonator for two ions [Geyer, Tannor, J. Phys. B 37 (2004) 73], to describe th…
Electron impact double ionization of helium from classical trajectory calculations
Tihamer Geyer
With a recently proposed quasiclassical ansatz [Geyer and Rost, J. Phys. B 35 (2002) 1479] it is possible to perform classical trajectory ionization calculations on many electron t…
Dynamical stabilization of classical multi electron targets against autoionization
Tihamer Geyer, Jan M Rost
We demonstrate that a recently published quasiclassical M\oller type approach [Geyer and Rost 2002, J. Phys. B 35 1479] can be used to overcome the problem of autoionization, which…
A mapping approach to synchronization in the "Zajfman trap": stability conditions and the synchronization mechanism
Tihamer Geyer, David J. Tannor
We present a two particle model to explain the mechanism that stabilizes a bunch of positively charged ions in an "ion trap resonator" [Pedersen etal, Phys. Rev. Lett. 87 (2001) 05…
