It is now ten years since it was first convincingly shown that below 1 K the ther mal conductivity and the heat capacity of amorphous solids behave in a way which is strikingly different to that of crystalline solids. Since that time there has been a wide variety of experimental and theoretical studies which have not only defined and clarified the low temperature problem more closely, but have also linked these differences between amorphous and crystalline solids to those suggested by older acoustic and thermal experiments (extending up to 100 K). The interest in this somewhat restricted branch of physics lies to a considerable extent in the fact that the differences were so unexpected. It might be thought that as the tempera ture, probing frequency, or more generally the energy decreases, a continuum de scription in which structural differences between glass and crystal are concealed should become more accurate. In a sense this is true, but it appears that there exists in an amorphous solid a large density of additional excitations which have no counterpart in normal crystals. This book presents a survey of the wide range of experimental investigations of these low energy excitations, together with a re view of the various theoretical models put forward to explain their existence and nature.

Download Influence of Magnetic Field on Dielectric Susceptibility of Amorphous Solids at Ultra Low Temperature Book in PDF, ePub and Kindle
The dielectric response of some amorphous solids below 100 mK is known to be sensitive to an applied magnetic field. This work presents new experimental data on the behavior of BK7, Aluminum-Barium-Silicate, Suprasil, Corning® microscope cover glass and Mylar® film (amorphous Polyethylene Terephthalate) samples in the temperature range from 2 mK to 100 mK in presence of a slowly varying magnetic field. We studied the dielectric constant by means of continuous wave AC capacitance measurements at 1 kHz. We observed hysteresis in the dielectric response to a magnetic field varying in a saw-like pattern with field strengths up to 2 milliTesla. The pattern of the response differs depending on the glass composition. The results presented in this work are consistent with previously made observations that nuclear spins greater than 1/2 play a crucial role in the observed magnetic field dependence.

Download Low-temperature Thermal And Vibrational Properties Of Disordered Solids: A Half-century Of Universal "Anomalies" Of Glasses Book in PDF, ePub and Kindle
This book, edited by M. A. Ramos and contributed by several reputed physicists in the field, presents a timely review on low-temperature thermal and vibrational properties of glasses, and of disordered solids in general. In 1971, the seminal work of Zeller and Pohl was published, which triggered this relevant research field in condensed matter physics. Hence, this book also commemorates about 50 years of that highlight with a comprehensive, updated review.In brief, glasses (firstly genuine amorphous solids but later on followed by different disordered crystals) were found to universally exhibit low-temperature properties (specific heat, thermal conductivity, acoustic and dielectric attenuation, etc.) unexpectedly very similar among them — and very different from those of their crystalline counterparts.These universal 'anomalies' of glasses and other disordered solids remain very controversial topics in condensed matter physics. They have been addressed exhaustively in this book, through many updated experimental data, a survey of most relevant models and theories, as well as by computational simulations.
