Available in PDF, EPUB and Kindle. Book excerpt: The non-linear properties observed in charge density wave compounds have been studied for many years. The quasi one-dimensional conductor NbSe3 is particularly important because a small electric field can depin the charge density wave above a threshold field, above which the charge density wave shows Zener-type non-linear behavior. Transport properties of the one-dimensional linear chain compound NbSe3 is measured using dc measurement, ac measurement, pulse techniques, direct mixing, and harmonic mixing as a function of dc bias voltage, applied frequencies, and in some cases the amplitude of an additional ac signal source. A phenomenological model, consisting of a shunt resistance in parallel with tunnel junction capacitor, based on the Hamiltonian tunneling matrix element is presented as a possible mechanism for correctly describing charge density wave dynamics. Our results appear to be consistent with time-correlated quantum nucleation of solitons and antisolitons. Furthermore, mixing experiment results are also compared with photon-assisted tunneling theory. Numerical calculations obtained from the model accurately reproduce the observed feature of charge density wave dynamics. The results reported here thus provide compelling evidence in favor of quantum tunneling as the mechanism for charge density wave depinning and transport.

This book was released on 2012-12-06 with total page 477 pages. Available in PDF, EPUB and Kindle. Book excerpt: The field of low-dimensional conductors has been very active for more than twenty years. It has grown continuously and both the inorganic and organic materials have remark able properties, such as charge and spin density waves and superconductivity. The discovery of superconductivity at high temperature in copper-based quasi two-dimensional conducting oxides nearly ten years ago has further enlarged the field and stimulated new research on inorganic conductors. It was obviously impossible to cover such a broad field in a ten day Institute and it seemed pertinent to concentrate on inorganic conductors, excluding the high Tc superconducting oxides. In this context, it was highly desirable to include both physics and chemistry in the same Institute in order to tighten or in some cases to establish links between physicists and chemists. This Advanced Study Institute is the continuation of a series of similar ones which have taken place every few years since 1974. 73 participants coming from 13 countries have taken part in this School at the beautiful site of the Centre de Physique des Houches in the Mont-Blanc mountain range. The scientific programme included more than forty lectures and seminars, two poster sessions and ten short talks. Several discussion sessions were organized for the evenings, one on New Materials, one on New Topics and one on the special problem of the Fermi and Luttinger liquids. The scientific activity was kept high from the beginning to the end of the Institute.

Download or read book Transport Studies and Phenomenological Model for Sliding Charge density Waves in Quasi one dimensional Conductors written by Williams Gregory Lyons and published by . This book was released on 1989 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transport studies examining the dynamics of one-dimensional charge-density wave (CDW) condensates are reported. Results using rf and dc, linear and nonlinear electrical transport techniques have been obtained at temperatures below the CDW transition in the quasi-one-dimensional materials o-TaS$sb3$, K$sb{0.03}$MoO$sb3$, (IaSe$sb4)sb2$I and NbSe$sb3$. Each of these materials exhibits a different set of CDW parameters due to differences in structural properties and electronic band structure. By correlating results obtained on these four materials systems and by considering a detailed overview of other experimental work in the field, the generic features of charge-density wave dynamics have been elucidated. A phenomenological model based on strong impurity pinning of the CDW phase is presented as a possible framework for resolving a long-standing debate over the correct theoretical description for CDW transport. Essentially all of the experimental results known to date on CDW systems can be interpreted within this framework. Numerical estimates are made from the model accurately reproducing the observed generic features of CDW dynamics. A brief summary is made of the shortcomings that have faced various other classical and quantum mechanical models. The study provides a solid reference point for future advances in microscopic charge-density wave theory. Sliding CDWs constitute only the second known example of a moving quantum ground state, the first being superconductivity. Unlike superconductivity, sample impurities break the translational invariance of an incommensurate CDW and pin it to the underlying crystal lattice. The universal features of the dynamics seen in CDW conductors are indeed very rich. Nonlinear conductivity occurs above a dc threshold for both deformable motion at high temperatures and rigid motion in fully gapped materials at low temperature. The ac response of the pinned CDW has a very complex behavior with up to three characteristic pinning frequencies and associated damping constants. Dielectric relaxation proves to be the most important element in properly describing the CDW phase dynamics, including motion of the charge-density wave in the periodic impurity pinning potential.

Available in PDF, EPUB and Kindle. Book excerpt: The latest addition to this series covers a field which is commonly referred to as charge density wave dynamics. The most thoroughly investigated materials are inorganic linear chain compounds with highly anisotropic electronic properties. The volume opens with an examination of their structural properties and the essential features which allow charge density waves to develop. The behaviour of the charge density waves, where interesting phenomena are observed, is treated both from a theoretical and an experimental standpoint. The role of impurities in statics and dynamics is considered and an examination of the possible role of solitons in incommensurate charge density wave systems is given. A number of ways to describe charge density waves theoretically, using computer simulations as well as microscopical models, are presented by a truely international board of authors.

Book excerpt: The volume constitutes the proceedings of the 13th International Conference on Noise in Physical Systems and 1/f Fluctuations (ICNF'95) held in Palanga, Lithuania, in the period 29 May - 3 June 1995.International conference of fluctuation phenomena has a rich history. Previous ones were held in St. Louis (USA, 1993), Kyoto (Japan, 1991), Budapest (Hungary, 1989), Montreal (Canada, 1983), etc. The conference proved to be successful in bringing together specialists in fluctuation phenomena in very different areas, and providing a bridge linking theorists and applied scientists involved in the design of new generation of electronic devices. Correspondingly, the volume covers fundamental aspects of noise in various fields of science and modern technology. Mesoscopic fluctuations, noise in high temperature superconductors, in nanoscale structures, in optoelectronic and microwave devices, fluctuation phenomena in biological systems and human body are in the spotlight.

Available in PDF, EPUB and Kindle. Book excerpt: Research activities in low dimensional conductors have shown a rapid growth since 1972 and have led to the discovery of new and remarkable phy sical properties unique to both molecular and inorganic conductors exhibi ting one-dimensional transport behaviour. This NATO Institute was a conti nuation of aseries of NATO Advanced Study Institutes of Worshops which took place at regular intervals till 1979. This is the first time, however, that charge density wave transport and electronic properties of low dimen sional organic conductors are treated on an equal footing. The program of the Institute was framed by tutorial lectures in the theories and experiments of low dimensional conductors. The bulk of the course covered two series of low-dimensional mate rials with their respective properties. 1) The I-D inorganic conductors exhibiting the phenomena of sliding charge density waves, narrow band noise, memory effects, etc ..• 2) Low-dimensional crystallized organic conductors giving rise to various possibilities of ground states, spin-Peierls, spin density wave, Peierls, superconductivity and magnetic-field induced spin density wave, etc ... Since it has been established from the beginning that this Institute was to be devoted essentially to the Physics of Low Dimensional Conductors, only one main course summarized the progress in chemistry and material preparation.

Book excerpt: ?Density Waves in Solids is written for graduate students and scientists interested in solid-state sciences. It discusses the theoretical and experimental state of affairs of two novel types of broken symmetry ground states of metals, charge, and spin density waves. These states arise as the consequence of electron-phonon and electron-electron interactions in low-dimensional metals.Some fundamental aspects of the one-dimensional electron gas, and of the materials with anisotropic properties, are discussed first. This is followed by the mean field theory of the phases transitions?discussed using second quantized formalism?together with the various experimental observations on the transition and on the ground states. Fluctuation effects and the collective excitations are reviewed next, using the Ginzburg-Landau formalism, followed by the review of the interaction of these states with the underlying lattice and with impurities. The final chapters are devoted to the response of the ground states to external perturbations.

This book was released on 2012-12-06 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume comprises the proceedings of a NATO Advanced Study In stitute held at Geilo, Norway, April 6 -16 1999. The ASI was the fifteenth in a series held biannually on topics related to cooperative phenomena and phase transitions, in this case applied to soft condensed matter and its configurations, dynamics and functionality. It addressed the current experimental and theoretical knowledge of the physical properties of soft condensed matter such as polymers, gels, complex fluids, colloids, granular materials and biomaterials. The main purpose of the lectures was to obtain basic understanding of important aspects in relating molecular configurations and dynamics to macroscopic properties and biological functionality. To our knowledge, the term Soft Condensed Matter was actually coined and used for the first time in 1989 at Geilo and some selected topics of soft matter were also given at Geilo in 1991, 1993 and 1995. A return to this subject 10 years after its instigation thus allowed a fresh look and a possibility for defining new directions for research.
