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 ...
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 ...
Despite the original model of the superradiance the quantum electromagnetic field is totally neglected here. The oscillators may be assumed to be placed for example on the cubic lattice with the lattice constant in the analogy to the crystal system of the condensed matter. The worse scenario of the defect of the absence of the two out-of-the ...
Gross Dealer Concession or GDC is the revenue to a brokerage firm when commissioned securities and insurance salespeople sell a product, whether it is an investment like stocks, bonds, or mutual funds, or insurance like life insurance or long term care insurance.

Models used in finance and investment assume ergodicity, explicitly or implicitly. The ergodic hypothesis is prevalent in modern portfolio theory, discounted cash flow (DCF) models, and aggregate indicator models that infuse macroeconomics, among others. The situations modeled by these theories can be useful.
Management is a type of labor with a special role of coordinating the activities of inputs and carrying out the contracts agreed among inputs, all of which can be characterized as "decision making". [1]
