Overtone Rabi oscillation of optically polarized triplet electron spins and nuclear hyperpolarization in powder

Koichiro Miyanishi, Takuya F. Segawa, Makoto Negoro +2

We report coherent overtone Rabi oscillations of optically-polarized triplet electron spins and nuclear hyperpolarization in powder samples at room temperature. The strong dependen…

Long-lived state in a four-spin system hyperpolarized at room temperature

Koichiro Miyanishi, Naoki Ichijo, Makoto Motoyama +3

A solution with hyperpolarized nuclear spins encoded into a long-lived state has been utilized for sensing chemical phenomena. In a conventional way, nuclear spins are hyperpolariz…
