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…

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…

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…
