Phonon surface mapping of graphite : disentangling quasi-degenerate phonon dispersions

A. Gruneis, J. Serrano, A. Bosak, M. Lazzeri, S.L. Molodtsov, L. Wirtz, Claudio Attaccalite, M. Krisch, A. Rubio, Francesco Mauri, T. Pichler

The two-dimensional mapping of the phonon dispersions around the K point of graphite by inelastic x-ray scattering is provided. The present work resolves the longstanding issue related to the correct assignment of transverse and longitudinal phonon branches at K. We observe an almost degeneracy of...

Universality of bias- and temperature-induced dephasing in ballistic electronic interferometers

Y. Yamauchi, M. Hashisaka, S. Nakamura, K. Chida, S. Kasai, T. Ono, R. Leturcq, K. Ensslin, D.C. Driscoll, A.C. Gossard, K. Kobayashi

We performed a transport measurement in a ballistic Aharonov-Bohm ring and a Fabry-P´erottype interferometer. In both cases we found that the interference signal is reversed at a certain bias voltage and that the visibility decays exponentially as a function of temperature, being in a strong...
