“Observation of new plasmons in the fractional quantum Hall effect: interplay of topological and nematic orders”

Science Advances, 5, eaav3407 (2019)

观察到分数量子霍尔nematic态的实验证据，被诺奖得主Haldane教授等人认为是手性引力子（Chiral graviton）的实验证据（Phys. Rev. Lett. 123, 146801, 2019），该文评论道“In a very recent experimental work（本工作）, inelastic light scattering was performed on the second Landau level states. We tentatively attribute the sharp resonance at ν = 7/3 (which is termed a new plasmon) to the graviton”。
