In quantum optics, superradiance is a phenomenon that occurs when a group of N emitters, such as excited atoms, interact with a common light field. If the wavelength of the light is much greater than the separation of the emitters, [2] then the emitters interact with the light in a collective and coherent fashion. [3]
Schematic representation of the difference between Dicke superradiance and the superradiant transition of the open Dicke model. The superradiant transition of the open Dicke model is related to, but differs from, Dicke superradiance. Dicke superradiance is a collective phenomenon in which many two-level systems emit photons coherently in free ...
Finance refers to monetary resources and to the study and discipline of money, currency, assets and liabilities. [a] As a subject of study, it is related to but distinct from economics, which is the study of the production, distribution, and consumption of goods and services.
Market trend: the tendency of financial markets to move in a particular direction over time. [8] Public float or Free float: the portion of shares of a corporation that are in the hands of public investors as opposed to locked-in stock held by promoters, company officers, controlling-interest investors, or government.
For example, $225K would be understood to mean $225,000, and $3.6K would be understood to mean $3,600. Multiple K's are not commonly used to represent larger numbers. In other words, it would look odd to use $1.2KK to represent $1,200,000. Ke – Is used as an abbreviation for Cost of Equity (COE).
Quantum finance is an interdisciplinary research field, applying theories and methods developed by quantum physicists and economists in order to solve problems in finance. It is a branch of econophysics. Quantum computing is now being used for a number of financial applications, including fraud detection, stock price prediction, portfolio ...
Corporate finance is an area of finance that deals with the sources of funding, and the capital structure of businesses, the actions that managers take to increase the value of the firm to the shareholders, and the tools and analysis used to allocate financial resources.
Finance also deals with the long term objective of maximizing the value of the business, while also balancing risk and profitability; this includes the interrelated questions of (1) capital investment, which businesses and projects to invest in; (2) capital structure, deciding on the mix of funding to be used; and (3) dividend policy, what to ...
