Winding-Sector Transitions and Thermodynamic Incommensurability in Helical Valence Bond Phase under Tilted Boundary Conditions
Yan Liu, Jie Lou, Yan Chen
We investigate the ground states of the staircase - model in the maximally anisotropic limit by employing projector quantum Monte Carlo simulations. To overcome b…
Spectroscopic evidences for the spontaneous symmetry breaking at the deconfined critical point of - model
Shutao Liu, Yan Liu, Chengkang Zhou +5
Recent numerical and theoretical studies on the two-dimensional - model suggests that the deconfined quantum critical point is actually a -symmetry-enhanced first-or…
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…
Ground State Phase Diagram of - Chain
Junhao Zhang, Jie Hou, Jie Lou +1
Distinct from the case, the fermionic systems with symmetry are expected to exhibit novel physics, such as exotic singlet formation. Using the density…
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…
Ground State of spin model on the checkerboard lattice
Junhao Zhang, Jie Hou, Jie Lou +1
Geometric frustration in quantum spin systems can lead to exotic ground states. In this study, we investigate the spin model on the checkerboard lattice to explore…
