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]
A superradiant laser is a laser that does not rely on a large population of photons within the laser cavity to maintain coherence. [1] [2]Rather than relying on photons to store phase coherence, it relies on collective effects in an atomic medium to store coherence.
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 ...
Managerial finance [29] is the branch of finance that deals with the financial aspects of the management of a company, and the financial dimension of managerial decision-making more broadly. It provides the theoretical underpin for the practice described above , concerning itself with the managerial application of the various finance techniques .
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.
The inset shows the free energy in the normal and superradiant phases In quantum optics , a superradiant phase transition is a phase transition that occurs in a collection of fluorescent emitters (such as atoms), between a state containing few electromagnetic excitations (as in the electromagnetic vacuum ) and a superradiant state with many ...
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).
Financial analysts often assess the following elements of a firm: Profitability - its ability to earn income and sustain growth in both the short- and long-term. A company's degree of profitability is usually based on the income statement, which reports on the company's results of operations;
