Fluctuations
Encyclopedia
Fluctuations may refer to:
- Quantum fluctuations arising from the uncertainty principle
- Primordial fluctuationsPrimordial fluctuationsPrimordial fluctuations are density variations in the early universe which are considered the seeds of all structure in the universe. Currently, the most widely accepted explanation for their origin is in the context of cosmic inflation...
, density variations in the early universe - Statistical fluctuationsStatistical fluctuationsStatistical fluctuations are fluctuations in quantities derived from many identical random processes. They are fundamental and unavoidable. It can be proved that the relative fluctuations reduce as the square root of the number of identical processes....
, very important in statistics, statistical mechanics, and thermodynamics - Thermal fluctuationsThermal fluctuationsIn statistical mechanics, thermal fluctuations are random deviations of a system from its equilibrium. All thermal fluctuations become larger and more frequent as the temperature increases, and likewise they disappear altogether as temperature approaches absolute zero.Thermal fluctuations are a...
, a statistical fluctuation in a thermodynamic variable - An alternative name for conjunctureConjunctureIn general, a conjuncture is a period marked by some watershed event which separates different epochs.In economics, conjuncture is a critical combination of events....
, a critical combination of events in economics - Vacuum Fluctuations
- Universal Conductance FluctuationsUniversal Conductance FluctuationsUniversal Conductance Fluctuations ' in quantum physics is a phenomenon encountered in electrical transport experiments in mesoscopic species. The measured electrical conductance will vary from sample to sample, mainly due to inhomogeneous scattering sites...
