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 $S = 1/2$ staircase $J$ - $Q_{3}$ 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 $S O (5)$ deconfined critical point of $J$ - $Q_{3}$ model

Shutao Liu, Yan Liu, Chengkang Zhou +5

Recent numerical and theoretical studies on the two-dimensional $J$ - $Q_{3}$ model suggests that the deconfined quantum critical point is actually a $S O (5)$ -symmetry-enhanced first-or…

Ground State of $SU (3)$ 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 $SU (3)$ spin model on the checkerboard lattice to explore…

Ground State Phase Diagram of $SU (3)$ $t$ - $J$ Chain

Junhao Zhang, Jie Hou, Jie Lou +1

Distinct from the $SU (2)$ case, the fermionic systems with $SU (N)$ symmetry are expected to exhibit novel physics, such as exotic singlet formation. Using the density…
