Author(s): Mirian Garcia Fernandez, Abhishek Nag, Stefano Agrestini, Sahil Tippireddy, Dirk Backes, Xiaoyang Chen, Urs Staub, Taka-Hisa Arima, and Kejin ZhouThe electron in a solid can be considered a bound state of the three independent, fundamental degrees of freedom creating quasiparticles: spinons, carrying the electron spin; plasmons, carrying the collective charge mode; and orbitons, carrying its orbital degree of freedom. These fundamental degree…[Phys. Rev. B 113, 235128] Published Mo...
