Abstract
Bose - Einsteinova kondenzacija je specifična vrsta faznog prijelaza preko koje je omogućeno proučavanje kvantnih efekata na makroskopskoj razini. Takav prijelaz karakterizira pad velikog broja bozona u osnovno stanje i opserviranje velikog vala materije. Teorija pretpostavljena od strane Alberta Einsteina dvadesetih godina 20. stoljeća daje statističku pozadinu o ponašanju plina bozona nakon sto se temperatura sustava smanji ispod kritične temperature. Da bi se mogla razviti intuitivna percepcija o prelasku iz običnog Boseovog plina u Bose - Einsteinov kondenzat, kreće se od uvođenja de Broglieve valne duljine te objašnjava kako ona postaje sve veća snižavanjem temperature sustava. Potom kvantno - statistički koncept daje konkretan izračun i objašnjenje kritične temperature. Predstavlja se pojednostavljeni teorijski model za Bose - Einsteinov kondenzat preko Gross - Pitaevskii jednadžbe, uz pobliže objašnjenje kroz raspršenje hladnih atoma i definiranje duljine raspršenja za nisko temperaturni sustav bozona. Nakon teorijskog objašnjenja daje se povijesni pregled teorijskih i eksperimentalnih radova koji su prethodili realizaciji Bose - Einsteinove kondenzacije, a usko su povezani s njom. Na kraju su opisane tehnike hlađenja sustava bozona te rezultati prvog postizanja kondenzata.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
