25 Dec 2018 Jin Jian-Zhao Liang Hao Xiao Xiang-Ru Wang Mu-Xue Chen Si-Ge Wu Xiao-Yuan Gong Qihuang Peng Liang-You

For the high-order harmonic generation in solids, we find a distinct and clean interference pattern in the high-energy end of the spectrum which can be interpreted as a Michelson interferometer of the Bloch electron. Our results are achieved by a numerical solution to the time-dependent Schr\"odinger equation of the quasi-electron in solids and can be explained by an analytical model based on the principle of the Michelson interferometry...
