SUMMARY:Séminaire du LPTMS: Mathias Albert - LPTMS\, salle 201\, 2ème ét
 age\, Bât 100\, Campus d'Orsay - 29 Mai 12 11:00
DESCRIPTION:Waiting times distribution of electrons flowing across mesoscop
 ic conductors\nMathias Albert (LPS\, Orsay)\n  Electronic transport throug
 h mesoscopic devices is known to be stochastic due to the quantum nature o
 f the charge carriers. The noise power spectrum as well as the Full Counti
 ng Statistics (FCS) provide many important informations about the system u
 nder study as it has been shown during the past 20 years. However the dist
 ribution of waiting times (WTD) between the detection of several charge ca
 rriers has been recently investigated and shown to be very powerful to und
 erstand the short time physics and correlations between different elementa
 ry events [1-3] in the same spirit than the level spacing distribution in 
 the spectral statistics of complex systems. In this talk we will use this 
 quantity to discuss the short time correlations in a perfect one dimension
 al quantum channel with a quantum point contact. Although the system is ex
 tremely simple\, the WTD reveals quite striking transport properties that 
 can be explained using random matrix theory in a totally unexpected contex
 t. Some other quantum states\, such as a train of Lorentzian pulses [4] wi
 ll be also considered and the relation between the WTD and the FCS also di
 scussed.  [1] T. Brandes\, Ann. Phys. (Berlin) 17\, 477 (2008).  [2] M. Al
