Competing and Intertwined Orders in Boson-Doped Mott Antiferromagnets
Abstract
Inspired by the recent experimental advances in cold atom quantum simulators, we explore the experimentally implemented bosonic t-t^{'}-J model on the square lattice using large-scale density matrix renormalization group simulations. By tuning the doping level δ and hopping ratio t^{'}/t, we uncover six distinct quantum phases, several of which go far beyond the conventional paradigm of phase-coherent superfluidity (SF) expected for bosonic systems. In particular, in the presence of antiferromagnetic (AFM) order, doped holes are tightly bound into pairs, giving rise to a pair density wave phase at low doping and small |t^{'}/t|, which is suppressed on the t^{'}
