A man and his equation: the anxiety-plagued nineteenth-century physicist who contributed significantly to our understanding of the second law of thermodynamics. Ludwig Boltzmann's grave in Vienna's Central Cemetery bears a cryptic epitaph: S = k log W. This equation was Boltzmann's great discovery, and it contributed significantly to our understanding of the second law of thermodynamics. In Anxiety and the Equation, Eric Johnson tells the story of a man and his equation: the anxiety-plagued nineteenth-century physicist who did his most important work as he struggled with mental illness. Johnson explains that “S” in Boltzmann's equation refers to entropy, and that entropy is the central quantity in the second law of thermodynamics. The second law is always on, running in the background of our lives, providing a way to differentiate between past and future. We know that the future will be a state of higher entropy than the past, and we have Boltzmann to thank for discovering the equation that underlies that fundamental trend. Johnson, accessibly and engagingly, reassembles Boltzmann's equation from its various components and presents episodes from Boltzmann's life—beginning at the end, with “Boltzmann Kills Himself” and “Boltzmann Is Buried (Not Once, But Twice).” Johnson explains the second law in simple terms, introduces key concepts through thought experiments, and explores Boltzmann's work. He argues that Boltzmann, diagnosed by his contemporaries as neurasthenic, suffered from an anxiety disorder. He was, says Johnson, a man of reason who suffered from irrational concerns about his work, worrying especially about opposition from the scientific establishment of the day. Johnson's clear and concise explanations will acquaint the nonspecialist reader with such seemingly esoteric concepts as microstates, macrostates, fluctuations, the distribution of energy, log functions, and equilibrium. He describes Boltzmann's relationships with other scientists, including Max Planck and Henri Poincaré, and, finally, imagines “an alternative ending,” in which Boltzmann lived on and died of natural causes.
Optical microcavities are structures that enable confinement of light to microscale volumes. The universal importance of these structures has made them indispensable to a wide range of fields. This important book describes the many applications and the related physics, providing both a review and a tutorial of key subjects by leading researchers from each field. The topics include cavity QED and quantum information, nanophotonics and nanostructure interactions, wavelength switching and modulation in optical communications, optical chaos and biosensors.
This book surveys semiconductor superlattices, in particular their growth and electronic properties in an applied electric field perpendicular to the layers. The main developments in this field, which were achieved in the last five to seven years, are summarized. The electronic properties include transport through minibands at low electric field strengths, the Wannier-Stark localization and Bloch oscillations at intermediate electric field strengths, resonant tunneling of electrons and holes between different subbands, and the formation of electric field domains for large carrier densities at high electric field strengths.
This book aims to serve as a practical guide for novices to design and conduct measurements of thermal properties at the nanoscale using electrothermal techniques. An outgrowth of the authors’ tutorials for new graduate students in their own labs, it includes practical details on measurement design and selection, sensitivity and uncertainty analysis, and pitfalls and verifications. The information is particularly helpful for someone setting up their own experiment for the first time. The book emphasizes the integration of thermal analysis with practical experimental considerations, in order to design an experiment for best sensitivity and to configure the laboratory instruments accordingly. The focus is on the measurements of thermal conductivity, though thermal diffusivity and thermal boundary resistance (thermal contact resistance) are also briefly covered, and many of the principles can be generalized to other challenging thermal measurements.The reader is only expected to have the basic familiarity with electrical instruments typical of a university graduate in science or engineering, and an acquaintance with the elementary laws of heat transfer by conduction, convection, and radiation.
Ferroelectric materials, in addition to possessing the unique property of a reversible, spontaneous polarization, exhibit a range of other significant and useful properties. These include high values of piezoelectric, pyroelectric, nonlinear optic, electrooptic, photorefractice and dielectric permittivity coefficients. Another fascinating property of ferroelectric materials is their photovoltaic effect. Photovoltaic effects have been extensively studied in the past in symmetric materials such as silicon. This volume is the first concentrated treatment of the characteristics, theory and potential applications of the photovoltaic effect in noncentrosymmetric materials, which include ferroelectrics and piezoelectrics. The book also deals with the relationship between the photovoltaic and the photorefractive effects. The latter has already been well-studied and is finding many applications in optical processing and computing. This volume should prove to be an important text as well as a comprehensive reference source for basic and applied researchers working on photovoltaic, photorefractive and other photoeffects in ferroelectrics and related materials.
This book brings together leading names in the field of nanoscale energy transport to provide a comprehensive and insightful review of this developing topic. The text covers new developments in the scientific basis and the practical relevance of nanoscale energy transport, highlighting the emerging effects at the nanoscale that qualitatively differ from those at the macroscopic scale. Throughout the book, microscopic energy carriers are discussed, including photons, electrons and magnons. State-of-the-art computational and experimental nanoscale energy transport methods are reviewed, and a broad range of materials system topics are considered, from interfaces and molecular junctions to nanostructured bulk materials. Nanoscale Energy Transport is a valuable reference for researchers in physics, materials, mechanical and electrical engineering, and it provides an excellent resource for graduate students.
