nollapistevärehtelyn
Nollapistevärehtelyn is a Finnish-language term used to describe residual oscillations that persist in a physical system as temperature approaches absolute zero, arising from zero-point energy of quantum fields. It is not a standard term in international physics literature; rather, it appears in some Finnish popular-science discussions and pedagogical contexts to convey the idea of ground-state fluctuations that survive at zero temperature.
The term denotes oscillatory behavior in observables that remains due to quantum fluctuations inherent in the
Nollapistevärehtely is a compound formed from nolla-piste (zero point) and värehtely (vibration or oscillation). The form
In quantum mechanics, the ground state of a harmonic oscillator and quantum fields possesses zero-point energy,
