An Introduction to Quantum Optics and Quantum Fluctuations
This is an introduction to the quantum theory of light and its broad implications and applications.A significant part of the book covers material with direct relevance to current basic and applied research, such as quantum fluctuations and their role in laser physics and the theory of forces between macroscopic bodies (Casimir effects).The book includes numerous historical sidelights throughout, and approximately seventy exercises. The book provides detailed expositions of the theory with emphasis on general physical principles.Foundational topics in classical and quantum electrodynamics are addressed in the first half of the book, including the semiclassical theory of atom-field interactions, the quantization of the electromagnetic field in dispersive and dissipative media, uncertainty relations, and spontaneous emission.The second half begins with a chapter on the Jaynes-Cummings model, dressed states, and some distinctly quantum-mechanical features of atom-field interactions, and includes discussion of entanglement, the no-cloning theorem, von Neumann's proof concerning hidden variable theories, Bell's theorem, and tests of Bell inequalities.The last two chapters focus on quantum fluctuations and fluctuation-dissipation relations, beginning with Brownian motion, the Fokker-Planck equation, and classical and quantum Langevin equations.Detailed calculations are presented for the laser linewidth, spontaneous emission noise, photon statistics of linear amplifiers and attenuators, and other phenomena.Van der Waals interactions, Casimir forces, the Lifshitz theory of molecular forces between macroscopic media, and the many-body theory of such forces based on dyadic Green functions are analyzed from the perspective of Langevin noise, vacuum field fluctuations, and zero-point energy.

Macroeconomic Theory : Fluctuations, Inflation and Growth in Closed and Open Economies
Macroeconomics is the application of economic theory to the study of the economy’s growth, cycle and price-level determination.Macroeconomics takes account of stylized facts observed in the real world and builds theoretical frameworks to explain such facts.Economic growth is a stylized fact of market economies, since England’s nineteenth-century industrial revolution.Until then, poverty was a common good for humanity. Economic growth consists in the persistent, smooth and sustained increase of per-capita income.A market economy shows periods of expanding and contracting economic activity.This phenomenon is the economic cycle. The price of money is the amount of goods bought with one unit of money, in other words, the inverse of the price level.Determination of the price level, or the value of money, is a fascinating subject in a fiat money economy.

Why can business cycle fluctuations be growth fluctuations?
Business cycle fluctuations can be growth fluctuations because the business cycle reflects the overall fluctuations in economic activity, including changes in the level of output and income. During an economic expansion, there is typically an increase in the level of economic growth, as businesses invest more, consumer spending rises, and overall economic activity expands. Conversely, during a recession, there is a decline in economic growth, as businesses cut back on investment, consumer spending decreases, and overall economic activity contracts. Therefore, business cycle fluctuations are closely tied to fluctuations in economic growth.
-
Are power fluctuations normal?
Power fluctuations can occur due to various reasons such as changes in demand, weather conditions, or issues with the power grid. While minor fluctuations are common and usually not a cause for concern, frequent or severe fluctuations can be a sign of a larger problem and may require attention from a professional. It is important to monitor power fluctuations and address any issues promptly to prevent damage to electrical devices and ensure the safety of the electrical system.
-
What are cyclical fluctuations?
Cyclical fluctuations refer to the regular, repetitive patterns of expansion and contraction in economic activity. These fluctuations are often referred to as business cycles and are characterized by periods of economic growth, followed by periods of economic downturn. The fluctuations are driven by changes in factors such as consumer spending, business investment, and government policies. Understanding and predicting these cyclical fluctuations is important for businesses, policymakers, and investors in making informed decisions.
-
What are weight fluctuations?
Weight fluctuations refer to changes in a person's body weight that occur over a short period of time. These fluctuations can be caused by various factors such as changes in diet, water retention, hormonal fluctuations, or fluctuations in muscle mass. It is normal for weight to fluctuate slightly from day to day, but significant or rapid fluctuations may be a sign of an underlying health issue and should be monitored closely.
