2excitation — /ek suy tay sheuhn, si /, n. 1. the act of exciting. 2. the state of being excited. 3. Elect. a. the application of voltage to an electric device, as an electron tube circuit, an antenna, or a dynamotor, often for producing a magnetic field in… …
3Excited state — Excitation is an elevation in energy level above an arbitrary baseline energy state. In physics there is a specific technical definition for energy level which is often associated with an atom being excited to an excited state.In quantum… …

5Squeezed coherent state — In physics, a squeezed coherent state is any state of the quantum mechanical Hilbert space such that the uncertainty principle is saturated. That is, the product of the corresponding two operators takes on its minimum value::Delta x Delta p =… …
6metastable state — Excited state (see excitation) of an atom, nucleus, or other system that has a longer lifetime than the ordinary excited states and generally has a shorter lifetime than the ground state. It can be considered a temporary energy trap or a somewhat …
7Fock state — A Fock state (also known as a number state), in quantum mechanics, is any element of a Fock space with a well defined number of particles (or quanta). These states are named after the Soviet physicist, V. A. Fock. Contents 1 Definition 2 Energy… …
8radiation — radiational, adj. /ray dee ay sheuhn/, n. 1. Physics. a. the process in which energy is emitted as particles or waves. b. the complete process in which energy is emitted by one body, transmitted through an intervening medium or space, and… …
