TL;DR: It is observed that electrons in the second Landau level of an extremely high-mobility two-dimensional electron system exhibit a very complex electronic behavior and a developing plateau at nu=2+3/8 points to the existence of other even-denominator states.

TL;DR: In this paper, a spectrum of experimental data on the fractional quantum Hall effect (FQHE) states in the first excited Landau level, obtained in an ultrahigh mobility two-dimensional electron system and at very low temperatures, is presented.

TL;DR: The Provisional Low Temperature Scale (PLTS-2000) as discussed by the authors is a compromise between NIST and the International Organization for Standardization (IOS) for the measurement of 3He melting pressure.

TL;DR: In this paper, the coefficients of linear thermal expansion and of isothermal compressibility have been measured for solid nitrogen in the temperature intervals from 4.2° to 40° K and 8°-40° K, respectively.

TL;DR: In this paper, a demagnetization of He3 has been described, with considerable attention devoted to thermometry, thermal equilibrium, and experimental techniques, and construction details of the high-sensitivity capacitive strain gauge are given.
