Evanescent continuous time random walks
E. Abad, S. B. Yuste, Katja Lindenberg
We study how an evanescence process affects the number of distinct sites visited by a continuous time random walker in one dimension. We distinguish two very different cases, namel…
Arrival statistics and exploration properties of mortal walkers
Santos B. Yuste, E. Abad, Katja Lindenberg
We study some of the salient features of the arrival statistics and exploration properties of mortal random walkers, that is, walkers that may die as they move, or as they wait to…
Barrier Height Formation in Organic Blends / Metal Interfaces: Case of (TTF-TCNQ) / Au(111)
Jose Ignacio Martinez, Enrique Abad, Juan Beltran +2
The interface between the tetrathiafulvalene / tetracyanoquinodimethane (TTFTCNQ) organic blend and the Au(111) metal surface is analyzed by Density Functional Theory calculations,…
Quasi-resonant neutralization of He+ ions at a germanium surface
D. Goebl, D. Roth, D. Primetzhofer +4
When low-energy He ions are scattered from a Ge surface, the fraction of positive ions exhibits characteristic oscillations as a function of ion energy. These oscillations are caus…
Exploration and Trapping of Mortal Random Walkers
S. B. Yuste, E. Abad, Katja Lindenberg
Exploration and trapping properties of random walkers that may evanesce at any time as they walk have seen very little treatment in the literature, and yet a finite lifetime is a f…
