Topological Pseudo-Goldstone Modes from Weakly Broken Dipole Conservation
Yan-Guang Yue, Jie Lou, Yan Chen
Weakly breaking a continuous symmetry in an ordered phase can convert its Goldstone modes into topological collective bands. We establish this mechanism in a neutral dipole condens…
Studying line defect at Deconfined Quantum Criticality via fuzzy sphere regularization
Shutao Liu, Shuai Yang, Jie Lou +1
The interplay between bulk critical fluctuations and nontrivial topology can enrich defect physics and give rise to novel defect universality classes. Understanding the fate of suc…
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…
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…
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…
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…
Accessing Excitation of Many-body Systems via Single-Mode Approximation within Quantum Monte Carlo Simulations
Yan Liu, Kemeng Wu, Shutao Liu +4
We extend the single-mode Approximation (SMA) into quantum Monte Carlo simulations to provides an efficient and fast method to obtain the dynamical dispersion of quantum many-body…
Six-component pairing instability in the SU(4) - chain
Jia-Cheng He, Jun-Hao Zhang, Jie Lou +1
We use the density matrix renormalization group (DMRG) method to study the SU(4) - chain. We find that, in addition to the conventional repulsive Luttinger liquid phase and p…
