Deterministic Loop Stochastic Series Expansion Algorithm for Quantum Spin Models in Magnetic Fields
Liuyun Dao, Yan-Cheng Wang, Hui Shao
The stochastic series expansion (SSE) algorithm is one of the most powerful quantum Monte Carlo methods and has been extensively applied to the study of quantum many body systems.…
Multiscale Excitations in the Diluted Two-dimensional S = 1/2 Heisenberg Antiferromagnet
Liuyun Dao, Hui Shao, Anders W. Sandvik
We study the excitation spectrum of the Heisenberg model on the randomly diluted square lattice by analytic continuation of QMC data. At dilution fractions and $p=…
SO(5) multicriticality in two-dimensional quantum magnets
Jun Takahashi, Hui Shao, Bowen Zhao +2
We resolve the nature of the quantum phase transition between antiferromagnetic and valence-bond solid ground states in square-lattice spin-1/2 magnets - the putative deconfined qu…
Magnon, doublon and quarton excitations in 2D S=1/2 trimerized Heisenberg models
Yue-Yue Chang, Jun-Qing Cheng, Hui Shao +2
We investigate the magnetic excitations of the trimerized Heisenberg models with intra-trimer interaction and inter-trimer interaction on four different two-dimensional…
Primary and Secondary Order Parameters in the Fully Frustrated Transverse Field Ising Model on the Square Lattice
Gabe Schumm, Hui Shao, Wenan Guo +2
Using quantum Monte Carlo simulations and field-theory arguments, we study the fully frustrated (Villain) transverse-field Ising model on the square lattice. We consider a "primary…
Progress on stochastic analytic continuation of quantum Monte Carlo data
Hui Shao, Anders W. Sandvik
We report multipronged progress on the stochastic averaging approach to numerical analytic continuation of quantum Monte Carlo data. With the sampled spectrum parametrized with del…
Unconventional U(1) to cross-over in quantum and classical -state clock models
Pranay Patil, Hui Shao, Anders W. Sandvik
We consider two-dimensional -state quantum clock models with quantum fluctuations connecting states with clock transitions with different choices for matrix elements. We study t…
Monte Carlo Renormalization Flows in the Space of Relevant and Irrelevant Operators: Application to Three-Dimensional Clock Models
Hui Shao, Wenan Guo, Anders W. Sandvik
We present a way to visualize and quantify renormalization group flows in a space of observables computed using Monte Carlo simulations. We apply the method to classical three-dime…
Random-Singlet Phase in Disordered Two-Dimensional Quantum Magnets
Lu Liu, Hui Shao, Yu-Cheng Lin +2
We study effects of disorder (randomness) in a 2D square-lattice quantum spin system, the - model with a 6-spin interaction supplementing the Heisenberg exchange…
Anomalous quantum-critical scaling corrections in two-dimensional antiferromagnets
Nvsen Ma, Phillip Weinberg, Hui Shao +3
We study the Néel-paramagnetic quantum phase transition in two-dimensional dimerized Heisenberg antiferromagnets using finite-size scaling of quantum Monte Carlo data. We r…
Nearly deconfined spinon excitations in the square-lattice spin-1/2 Heisenberg antiferromagnet
Hui Shao, Yan Qi Qin, Sylvain Capponi +3
We study the dynamic spin structure factor of the spin- square-lattice Heisenberg antiferromagnet and of the - model (with 4-spin interactions and Heisenberg exchang…
Quantum criticality with two length scales
Hui Shao, Wenan Guo, Anders W. Sandvik
The theory of deconfined quantum critical points describes phase transitions at temperature T = 0 outside the standard paradigm, predicting continuous transformations between certa…
