A monolithic 0-f scheme-based femtosecond optical frequency comb directly driven by a high-power Ti:sapphire laser oscillator is demonstrated.The spectrum cover
We report the realization of quantum logic spectroscopy on the 1S0 → 3P0 clock transition of a single 27Al+ ion.This ion is trapped together with a 40Ca+ ion i
The energetic-particle-induced geodesic acoustic mode (EGAM) is studied using gyrokinetic particle simulations in tokamak plasmas.In our simulations,exponential
Traditional "magic numbers" were once regarded as immutable throughout the nuclear chart.However,unexpected changes were found for unstable nuclei around N =20.
