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…

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…
