TL;DR: Developpement d'une nouvelle spectroscopie permettant l'etude des variations de la chaleur massique des liquides avec la frequence avec the frequence.
Abstract: The glass transition has historically been viewed as an anomaly involving the specific heat of supercooled liquids. It is also associated with a divergence of the relaxation times for liquid rearrangements. We have developed a new spectroscopy to study the frequency dependence of the specific heat of liquids which connects these two approaches. We report measurements as a function of temperature of the distribution of relaxation times which are directly responsible for the glass transition in glycerol.

TL;DR: In this paper, the effect of electron-electron interactions on the impurity-averaged transport properties of disordered metal rings or arrays was studied and it was shown that the inclusion of these interactions does not change the periodicity with flux when an impurity average is performed.
Abstract: We study the effect of electron-electron interactions on the impurity-averaged transport properties of a disordered metal ring or array. We show that the inclusion of these interactions does not change the periodicity with flux when an impurity average is performed. We prove this statement in the context of a tight-binding Hubbard model for a ring with a symmetric distribution of on-site energies.

TL;DR: Aharonov and Bohm as mentioned in this paper showed that the interference pattern caused by an electron diffracting from the two slits depended upon the amount of magnetic flux enclosed by the two possible paths but not upon the strength of the magnetic field in the region of the electron.
Abstract: In 1959 Aharonov and Bohm1 proposed a two-slit diffraction experiment which implied that it was the vector potential, A, not the magnetic field, B, which was of fundamental importance in quantum mechanics. Their experiment showed that the interference pattern caused by an electron diffracting from the two slits depended upon the amount of magnetic flux enclosed by the two possible paths but not upon the strength of the magnetic field in the region of the electron.
