Phenomenon of a stronger trapping behaviour in $\hat{I}›$-type quantum systems with symmetry

Boris Volkov, Anastasia Myachkova, Alexander Pechen

$\hat{I}›$, $V$, $\hat{I}ž$ (ladder), and other three-level quantum systems with one forbidden transition (referred here as $\hat{I}›$-type systems) play an important role in quantum physics. Variou…
