Spina saspiešanas stacionārā elektriskā laukā modelēšana divatomu molekulu koherentā ierosmē

subject

description

Stāvokļa spina saspiešana ļauj uzlabot atsevišķu mērierīču, piemēram, optisko magnetometru, jutību un ātrdarbību, salīdzinot ar vienkārši izstieptiem stāvokļiem. Saspiešanas process ir intensīvi pētīts nestacionāros gadījumos, bet eksperimentāli izveidot iekārtu, kas ļautu veikt tik precīzas manipulācijas ar atomiem/molekulām ir sarežģīti. Šī iemesla dēļ pievilcīga ir ideja par spina saspiešanu stacionārā ierosmē pie pastāvīga elektriskā lauka. Darbā ir izstrādāts modelis, kas apraksta divu līmeņu sistēmu, kurā pētīta spina saspiešana atkarībā no relaksācijas un pumpēšanas parametriem, pieliktā elektriskā lauka un sistēmas impulsa momenta, kā arī modelē gaismas absorbcijas signālu. Rezultātā iegūta saspiestības parametra atkarība no iepriekš minētajiem parametriem.
