Stiefel Liquids: Possible Non-Lagrangian Quantum Criticality from Intertwined Orders
We propose a new type of quantum liquids, dubbed Stiefel liquids, based on (2+1)-dimensional nonlinear sigma models on target space SO(N)/SO(4), supplemented with Wess-Zumino-Witten terms. We argue that the Stiefel liquids form a class of critical quantum liquids with extraordinary properties, such...
