Al comenzar a escribir esta charla me acuerdo de la excitación general que permeaba el campo de la física de bajas temperaturas en 1971. Se habían desarrollado nuevas tecnologías de enfriamiento, y todos sentían que una física nueva, interesant

Como un estudiante graduado a mediados de los años 60, fui atraído a la física de bajas temperaturas por las nuevas y poderosas tecnologías de enfriamiento que se estaban desarrollando por ese entonces. Yo estaba seguro que estas tecnologías nos

Étnicamente, provengo de una familia mezclada. Mi padre era hijo de inmigrantes judíos que abandonaron Rusia poco después de comienzos de siglo, y mi madre era la hija de un pastor luterano cuyos padres provenían de lo que hoy es Slovaquia. Sin e

After the temporary application of a strong electric bias field to a glass sample at temperatures in the milli-Kelvin range its dielectric constant is increased and then decays slowly back to its equilibrium value. We studied these dielectric non-equ

Continuous wave NMR studies of superfluid 3 He in 99.4%, 98.7% and 98.3% porosity silica aerogels show similar phase diagrams, with an equal spin pairing (ESP) A-like state stable near Tc,a, and a B-like phase stable at lower temperatures. On cooling

By their very nature, those discoveries which most change the way we perceive our physical universe are difficult to anticipate. How then, are such discoveries made, and what experimental approaches are most likely to lead to discoveries? In this art

New NMR studies of 3He in high-porosity aerogel reveal a phase transition from an A-like to a B-like phase on cooling. The evidence includes frequency shift and magnetic susceptibility data, and similar behavior is found in two quite different aeroge

Using the capacitance of a glass sample as its own thermometer, we have measured the thermal conductivity of two glasses below 700mK. This technique avoids any thermal boundary resistance between the thermometer and the sample. In addition, since the

We report continuous-wave NMR measurements on superfluid 3 He contained inside high porosity aerogel at 3.24 MPa, in a 28.4 mT magnetic field, and down to 0.9 mK. Three different purities of 3 He were used: pure 3 He, 3 He with enough 4 He to replace
