The density (~dark area) of electrons in the dot for nine levels. Dashed lines are the lines of constant potential V = 20,0, -20, -40, -60, and -80. The single-channel wire is attached from the left. About 95% of the norm of the wave function in the dot is shown. P. G. Silvestrov and Y. Imry, Cond-Mat/9911205vl 13 Nov 1999.

 Research Highlights:

1. The major subject of Dephasing of Quantum interference in mesoscopics, especially at low temperatures. Some of the work is in collaboration with Y. Levinson, Y. Levit and A. Stern, with M. Heiblum's experimental group at the WIS and with Z. Ovadyahu at the Hebrew Univ.. [2,4].
2. Theory of Quantum- and shot-noise, emphasizing the connections between the noise power and the emission-absorption charactristics of the system, including effects familiar from Quantum Optics. This is in collaboration with U. Gavish (PhD student) and with Y. Levinson [5,6].
3. Low dimensional mesoscopic structures, resonators and "quantum dots". This includes thermodynamic and transport [3] phenomena. Some of this work [7] is in collaboration with P. Silvestrov (Novosibirsk).
4. Normal-superconducting interfaces, the proximity effects and ultrasmall superconductors [8]. In collaboration with Y. Levinson and with Z. Ovadyahu (HU), and G. Schoen and C. Bruder (Karlsruhe and Basel) and with M. Schechter (HU).
5. Effects of electron-electron interaction on localization of electrons in disordered systems and spectral correlations (with collaboration with U. Smilansky, with P. Woelfle of Karlsruhe and with J.-L Pichard of Saclay). This subject [9,10] is intimately related to the insulator-normal metal-superconductor phase diagram of matter (some of this work is in collaboration with A. Aharony and O. Entin-Wohlman at Tel-Aviv Univ.).
6. Phase measurements in AB interferometers, Fano-type effects and the ability to determine phase-shifts [11]; strongly motivated by the experimental work in M. Heiblum's group. In collaboration with Y. Levinson, with A. Aharony and O. Entin-Wohlman of TAU and with A. Schiller of HU.
