Elastic response of [111]-tunneling impurities
P. Nalbach, O. Terzidis, K. Topp +1
We study the dynamic response of a [111] quantum impurity, such as lithium or cyanide in alkali halides, with respect to an external field coupling to the elastic quadrupole moment…
Rotating wave approximation: systematic expansion and application to coupled spin pairs
B. Thimmel, P. Nalbach, O. Terzidis
We propose a new treatment of the dynamics of a periodically time-dependent Liouvillian by mapping it onto a time-independent problem and give a systematic expansion for its effect…
A model for ripple instabilities in granular media
Orestis Terzidis, Philippe Claudin, Jean-Philippe Bouchaud
We extend the model of surface granular flow proposed in \cite{bcre} to account for the effect of an external `wind', which acts as to dislodge particles from the static bed, such…
Cubic Defects: Comparing the Eight-State-System with its Two-Level-Approximation
P. Nalbach, O. Terzidis
Substitutional defects in a cubic symmetry (such as a lithium defect in a KCl host crystal) can be modeled appropriately by an eight-state-system. Usually this tunneling degree of…
