Recent observations favour an accelerating Universe dominated by the dark energy. We take the effective YangMills condensate as the dark energy and couple it to
We carry out the in-situ high pressure energy dispersive x-ray diffraction measurements on natural epitote by using diamond anvil cell. The pressure dependence
Generation of third-order harmonics at 800 nm of femtosecond laser pulses is studied in neutral atmospheric air and in plasma of optical breakdown in air. Its e
