The wetting behavior of dust by droplets is investigated by experiments and numerical simulation methods.Experimental observation reveals that the surface of a
We report a cladding-pumped Tm3+-doped domestic silica fiber laser operated at 2pm and actively Q-switched with an acousto-optic modulator.Pulse trains are obta
We report an experiment on the adiabatic cooling of Rb atoms in an atomic fountain to a temperature as low as 1.5μK, which is roughly twice the recoil temperat
The Dynamical Casimir effect and collective excitations in atom ensemble are investigated in a non-stationary cavity.The results show that the dynamical Casimir
