Hierarchical Trion Formation and Fractionalized Solitons in One Dimension
Yan-Guang Yue, Qi Song, Jie Lou +1
Stabilizing commensurate trions in one-dimensional quantum mixtures is typically hindered by phase separation. Within the conventional density-driven framework, the asymmetri…
Condensation of Composite Bosonic Trions in Interacting Bose-Fermi Mixtures
Qi Song, Jie Lou, Yan Chen
We reveal a quantum coherent state characterized by composite bosonic trions, wherein paired fermions further bind with bosons, in one-dimensional Bose-Fermi mixtures.This phase em…
Floquet-Engineered Hybrid Topological Orders with Majorana Edge Modes in Number-Conserving Fermionic Quantum Simulators
Zhi Lin, Qi Song, Sheng Yue +3
We develop an experimental protocol based on Floquet-engineered ultracold fermions in optical lattices, enabling the emulation of pair-hopping and competing singlet/triplet pairing…
Exotic Superfluid with Emergent flux in a one-dimensional Bose-Fermi mixture
Qi Song, Jie Lou, Yan Chen
We find a novel chiral superfluid (CSF) phase in a one-dimensional Bose-Fermi Hubbard model with significant mass and density imbalance between the two species. In the CSF phase, b…
