This book was released on 2006-03-06 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: Starting from the early experiments, this detailed presentation, containing more than 500 references, provides a comprehensive review on current-induced nonequilibrium phenomena in quasi-one-dimensional superconductors, leading the reader from the fundamentals to the most recent research results. Experiments on monocrystalline filaments (whiskers) - including those obtained by the author - are compared with results on long thin film microbridges and related species and interpreted within the theoretical framework.

Download or read book Electrodynamics of High temperature Superconductors written by Alan M. Portis and published by World Scientific. This book was released on 1993 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: These lectures are concerned with the application of high temperature superconductors to both passive and active high-frequency devices.The central issue addressed is the electrodynamics of granular superconductors, particularly where grain boundaries (either natural or synthetic) act as Josephson weak-links. Grain boundaries are responsible for residual dissipation and for unwanted dependence of the electromagnetic properties on ambient magnetic fields and on elevated power level. Properly controlled, similar weak-links are the key to high sensitivity dc and rf SQUIDS at readily accessible temperatures, and to modulators, mixers and detectors. Such structures may conveniently lead to superconductive electronic devices as well as coherent sources of radiation in the very far infrared.

Available in PDF, EPUB and Kindle. Book excerpt: The phenomenon of superconductivity has attracted the attention of both the fundamental science community and industry and technology for more than a century. Effects related to the macroscopic manifestation of quantum mechanical order give rise to a better understanding of the processes occurring in the micro-world and lead to new opportunities for applied science such as, for example, creation of the Superconducting QUantum Interference Device [1] - SQUID - allowing for measuring very low magnetic fields, based on Josephson effect. Superconducting electromagnets create extremely high magnetic field and are used in magnetic resonance imaging (MRI) and nuclear magnetic resonance (NMR) machines, fusion reactors such as tokamaks etc. The experimental studies of superconductivity in the non-equilibrium started soon after the observation of the superconducting energy gap in optical spectroscopy [2] and the development of the microscopic theory of superconductivity by Bardeen, Cooper and Schrieffer [3]. The first experiments were performed in the quasi-continuous excitation regime, without direct access to the dynamics of superconductors [4]. Later on, with the advent of femtosecond laser technology, time-resolved experiments were utilized to investigate the evolution of the optical properties of superconductors on an ultrafast timescale [5]. This thesis presents the results of the studies on the two-band superconductor MgB2 utilizing time-resolved spectroscopy in the Terahertz (THz) range of electromagnetic radiation. We conducted systematic experiments to obtain the dynamics of the superconducting order in the two-band superconductor MgB2 as a function of temperature, excitation energy density with the resolution in time- and frequency-domain using different excitation and probing methods. Our results show that the initial Cooper-pair breaking dynamics driven by the resonant THz excitation exhibits unexpected slowing down on the tens-of-picoseconds timescale implying strongly non-thermal distribution of the photoexcited quasiparticles. The initial suppression of superconductivity is followed by the recovery of the superconducting state, and the recovery dynamics exhibit temperature and absorbed energy density dependence of the recovery time, both for the case of the resonant excitation with intense THz pulses and the off-resonant excitation with near infrared (NIR) laser pulses. The most non-trivial observation is the temperature dependence of the relative photoinduced gap suppression, which experiences a dip around 0.6·Tc instead of a monotonous in- crease following the quasi-thermal suppression of the gap. This observation suggests the existence of a process competing with the photoinduced gap suppression, leading to a dynamic "cooling" of a superconductor. Such a process can be a consequence of a non-thermal QP distribution considered by Eliashberg in the 1970's [6]. Compared to the enhancement of superconductivity with microwave radiation, where an increase in Tc of ≈ 1 % was demonstrated, we observe a decrease in the pair-breaking efficiency by a factor of ≈ 2. The spectrally-resolved conductivity dynamics shows that the technique is sensitive to the spectral features associated with the superconducting gap and can provide rich information about the non-equilibrium optical properties of the superconductor and help to better under- stand the complex ground state of the multi-band superconductivity. Detailed interpretation of the obtained results, however, requires further theoretical analysis of both equilibrium and non-equilibrium electrodynamics of multi-band superconductors.

This book was released on 2012-03-01 with total page 699 pages. Available in PDF, EPUB and Kindle. Book excerpt: The importance of phonons has long been recognized by research ers in nonequilibrium superconductivity. Similarly, experimentalists studying phonons at low temperatures have relied heavily on supercon ductors as sources and detectors. To a large extent this symbiotic relationship has developed with a general mutual awareness; however, to our knowledge these subjects have never been treated together in conferences or study institutes. It was with the hope of further contributing to the awareness and communication between workers in these areas that this NATO Advanced Study Institute (ASI) has been conceived. A second, but equally important, reason for holding this ASI is to fill a void by providing the first general textbook in this important area of physics. Therefore, there was an emphasis on the tutorial nature of the lectures and written contributions to this textbook. It should not go unnoticed that the experimental and theoretical concepts covered in this textbook are of paramount importance to the various applications of superconductors. Almost by definition, the use of a superconductor implies a nonequilibrium state! For example, phonon conduction to the helium bath is important in devices ranging from microscopic Josephson junctions to large scale magnets and transmission lines. Knowledge of the more fundamental nonequilibrium effects can aid in our understanding of devices as well as provide the potential for entirely new applications.
