English term or phrase: to collapse the quantum potential of the field's reality quanta
My question refers to the word "collapse" in the field of quantum physics. I heard the expression "to collpase a wavelength" before, but how would you translate that?

Kollabieren des Quantenpotentials ... um das Quantenpotential kollabieren zu lassen
Explanation:
Kollaps der Wellenfunktion oder Zustandsreduktion ist ein Begriff der Kopenhagener Deutung der Quantenmechanik. In der Quantenmechanik wird ein physikalisches System durch eine Überlagerung ("Superposition") unterschiedlicher Zustände beschrieben. In der Bra-Ket-Notation lautet dies [Formel]
Der Gesamtzustand ψist eine Überlagerung aller möglichen Eigenzustände
φijeweils mit Gewicht ci. Wird an einem solchen System eine Messung durchgeführt, so werden die Experimentatoren stets einen einzigen Messwert (Eigenwert eines Eigenzustands) ermitteln. Formal bedeutet dies, dass die Superposition von Zuständen durch die Messung auf einen einzelnen dieser Zustände reduziert bzw. projiziert wird. Das gemessene System befindet sich dadurch nach der Messung in exakt dem gemessenen Zustand. Dieser Übergang vom Zustand der Superposition in einen eindeutig bestimmten Zustand wird als Zustandsreduktion bezeichnet. Da der Ausgangszustand als Zustand der Schrödinger'schen Wellenfunktion dargestellt wird, spricht die Kopenhagener Interpretation auch vom "Kollaps der Wellenfunktion".

In quantum mechanics, wave function collapse is the phenomenon in which a wave function—initially in a superposition of several eigenstates—appears to reduce to a single eigenstate after interaction with an observer.[1] It is the essence of measurement in quantum mechanics, and connects the wave function with classical observables like position and momentum. Collapse is one of two processes by which quantum systems evolve in time; the other is continuous evolution via the Schrödinger equation.[2] However in this role, collapse is merely a black box for thermodynamically irreversible interaction with a classical environment.[3] Calculations of quantum decoherence predict apparent wave function collapse when a superposition forms between the quantum system's states and the environment's states. Significantly, the combined wave function of the system and environment continue to obey the Schrödinger equation.[4]

The de Broglie–Bohm theory, also called the pilot-wave theory, Bohmian mechanics, and the causal interpretation, is an interpretation of quantum theory. In addition to a wavefunction on the space of all possible configurations, it also includes an actual configuration, even when unobserved. The evolution over time of the configuration (that is, of the positions of all particles or the configuration of all fields) is defined by the wave function via a guiding equation. The evolution of the wavefunction over time is given by Schrödinger's equation.
The de Broglie–Bohm theory is explicitly nonlocal: The velocity of any one particle depends on the value of the guiding equation, which depends on the whole configuration of the universe.

Collapse of the wavefunction
De Broglie–Bohm theory is a theory that applies primarily to the whole universe. That is, there is a single wavefunction governing the motion of all of the particles in the universe according to the guiding equation. Theoretically, the motion of one particle depends on the positions of all of the other particles in the universe.

t requires a special setup for the conditional wavefunction of a system to obey a quantum evolution. When a system interacts with its environment, such as through a measurement, the conditional wavefunction of the system evolves in a different way. The evolution of the universal wavefunction can become such that the wavefunction of the system appears to be in a superposition of distinct states
:
There remain difficulties using the Bohmian approach, mostly associated with the formation of singularities in the quantum potential due to nodes in the quantum wavefunction.

Asker: I know, I of course also tried on Google and everywhere else, and there was no hit. Your explanation is extremely helpful, though, thanks a lot!

Asker: Thanks again, Johannes!


Peer comments on this answer (and responses from the answerer)
agree  Hans-Jochen Trost: I agree with the translation (see my reference entry), but please note that collapse of the quantum potential does not appear as a concept anywhere in quantum physics. The discussion of collapse of the wave function does not help anything here.

  -> I tried only to translate the term (No Ghit for "to collapse the quantum potential " in the internet). Thank you nevertheless!

Reference: This looks like metaphysics rather than quantum physics.

Reference information:
Googling for it, I came across a link for collapsing a quantum potential, see first link below.
A short discussion of how quantum theory and metaphysics intersect (or are made to intersect), is here:
http://www.colorado.edu/philosophy/vstenger/Quantum/qmeta.ht...
The concept "quantum potential" was introduced by David Bohm in the early 1950s, so you may want to look for a German text discussing David Bohm's work as a source for a workable translation of it, and then just let it "kollabieren". de.wikipedia.org may have enough of an answer.
Similarly, one place where I found the term "reality quantum" is in work by Menas Kafatos and Robert Nadeau (an astrophysics/philosophy tandem), see second link below.
