SUMMARY:Insights into Single Molecule Dynamics
DESCRIPTION:Featuring Dr. Golan Bel\, Los Alamos National Lab \nHosted by: 
	Sidney Redner\n\nPart of the Biophysics/Condensed Matter Seminar Series.\n\
	nAbstract:\nRecent advances in technology have enabled studying the dynamic
	s of single molecules. What new\ninsights can be revealed by these experime
	nts which cannot be seen in bulk measurements? In this talk.  I will focus 
	on two examples where we showed that studying single molecules reveals new 
	phenomena. The first is the case of anomalous diffusion in an equilibrium e
	nvironment.  I will discuss a few models for anomalous diffusion where weak
	 ergodicity breaking emerges.  The concept of weak ergodicity breaking will
	 be clarified and I will discuss how it enables us to distinguish between d
	ifferent models for anomalous diffusion. The second example I will discuss 
	is a non-equilibrium system\, a single molecule excited by a monochromatic 
	laser field. I will introduce the moment-generating function for photon emi
	ssions in which the frequencies of the fluoresced photons are explicitly co
	nsidered. Calculations were performed for the case of a two-level dye molec
	ule\, showing that measured photon statistics will display a strong and non
	intuitive dependence on detector bandwidth. These two examples show that si
	ngle molecule measurements can provide new information about the observed s
	ystem both in equilibrium and non-equilibrium conditions. Moreover\, new ph
	enomena which are observed only at the single molecule level can favor cert
	ain microscopic models over others.
