The correlation between electronic and crystal structures of 1T-TiSe_{2} in the charge-density wave (CDW) state is studied by x-ray diffraction in order to clarify basic properties in the CDW state, transport properties, and chirality. Three families

In this work, we use ultrafast pump-probe nonresonant and resonant x-ray diffraction to track the periodic lattice distortion and the electronic charge density wave in 1T-TiSe_{2} upon optical excitation. We observe a fluence regime in which the peri
