초록: Rare earth pyrochlores, with a chemical formula A2B2O7, have been recently focused as possible candidates of spin liquid. Beyond classical spin ice state, quantum fluctuations are believed to play an important role in A-site spin system to describe such an exotic spin liquid phase. Motivated by recent experiments on rare earth pyrochlores, we study the pseudo spin-1/2 model, which is quite generic to describe rare earth pyrochlores with integer spins, in the presence of spin-orbit coupling and crystalline electric field. Using a new "gauge mean field theory", we show the possible exotic ground states and also briefly discuss the experimental suggestions based on our theory.
