Abstract

In this talk I will discuss the phenomena of dephasing and phase lapses as they occur in two setups operating in the quantum Hall regime Both setups consist of a quantum dot and an electronic Mach Zehnder interferometer Dephasing i e loss of coherent transport and phases lapses i e abrupt jumps in the phase of the transmission amplitude turn out to be intimately related in these setups In the first setup transport through a chiral channel is affected by charge fluctuations
