Journal ArticleDOI
Beyond Brownian motion
TL;DR: Early uses of probability arguments focused on distributions with well-defined means and variances, such as the Gaussian law of errors as discussed by the authors, in which the mean represented the most probable value from a series of repeated measurements of a fixed quantity, and the variance was related to the uncertainty of those measurements.
Journal ArticleDOI
A single-molecule optical transistor
J. Hwang,M. Pototschnig,Robert Lettow,Gert Zumofen,Alois Renn,Stephan Götzinger,Vahid Sandoghdar +6 more
TL;DR: It is demonstrated that a single dye molecule can operate as an optical transistor and coherently attenuate or amplify a tightly focused laser beam, depending on the power of a second ‘gating’ beam that controls the degree of population inversion.
Journal ArticleDOI
Efficient coupling of photons to a single molecule and the observation of its resonance fluorescence
TL;DR: In this article, the Mollow fluorescence triplet was detected by focusing the excitation light near to the extinction cross-section of a molecule, which enables the detection of resonance fluorescence over nine orders of magnitude of excitation intensity and separate its coherent and incoherent parts.
Journal ArticleDOI
Controlled coupling of counterpropagating whispering-gallery modes by a single Rayleigh scatterer: a classical problem in a quantum optical light.
TL;DR: These experiments present experiments where a single subwavelength scatterer is used to examine and control the backscattering induced coupling between counterpropagating high-Q modes of a microsphere resonator, and reveal the standing wave character of the resulting symmetric and antisymmetric eigenmodes.
Journal ArticleDOI
Scale-invariant motion in intermittent chaotic systems
Gert Zumofen,Joseph Klafter +1 more
TL;DR: This work investigates the dynamics generated from iterated maps and analyzes the motion in terms of the probabilistic continuous-time random-walk (CTRW) approach using the CTRW framework and scaling arguments.
