Brief explanation. Doppler cooling involves light with frequency tuned slightly below an electronic transition in an atom. Because the light is detuned to the "red" (i.e. at lower frequency) of the transition, the atoms will absorb more photons if they move towards the light source, due to the Doppler effect.

The Dunning–Kruger effect is defined as the tendency of people with low ability in a specific area to give overly positive assessments of this ability. [2][3][4] This is often seen as a cognitive bias, i.e. as a systematic tendency to engage in erroneous forms of thinking and judging. [5][6][7] In the case of the Dunning–Kruger effect, this ...
The Doppler effect (also Doppler shift) is the change in the frequency of a wave in relation to an observer who is moving relative to the source of the wave. [1][2][3] The Doppler effect is named after the physicist Christian Doppler, who described the phenomenon in 1842. A common example of Doppler shift is the change of pitch heard when a ...
Physical principle of Sisyphus cooling: The atoms are running against the potential energy, become excited into a higher band, fall back into a low-energy state (i.e. from the rather high "blue" state upwards, then immediately backwards to the lower "red" state), always on the left-hand side, from which, after one and a half of the "red" or "blue" period, say, of the laser action, they get ...
D015225. Magnetoencephalography (MEG) is a functional neuroimaging technique for mapping brain activity by recording magnetic fields produced by electrical currents occurring naturally in the brain, using very sensitive magnetometers. Arrays of SQUIDs (superconducting quantum interference devices) are currently the most common magnetometer ...
t. e. In social psychology, the boomerang effect, also known as "reactance", refers to the unintended consequences of an attempt to persuade resulting in the adoption of an opposing position instead. It is sometimes also referred to as "the theory of psychological reactance ", stating that attempts to restrict a person's freedom often produce ...
